Start with a fake university

PS: After writing the game in one go, there should be more than 10,000 words, not to be missed!

——

"Congratulations to Imperial College for being the first to solve [Question B]. It took 11 minutes and 09 seconds!"

Following the announcement of the competition committee, behind the area where the three players from the Imperial College team are located, a balloon marked "FIRST-PROBLEM-SOLVED" rose up.

This is the honor of the first team to solve every problem.

When I heard that it was Imperial College London, Huang Youjie was a little disappointed. He thought it was possible that Abin and the others had solved [Question B].

"Imperial College of Technology is very strong. There is no doubt about it. It took 11 minutes and 09 seconds, which is very powerful." Ding Yue couldn't help frowning.

If this trend continues, will your Wucheng University of Arts and Sciences fail to enter the final championship?

The format of the ACM competition is to count all the accumulated time for answering questions. The shorter the answering time, the better the chance of winning the championship.

If there is still the last question left, the time gap between many colleges and universities is only a few minutes. After ten minutes, there is a chance to recover with the last question.

Even if the time difference is twenty minutes or half an hour, there is hope.

I am afraid of those universities with abnormal strengths. The first few questions have been solved in about ten minutes without moving, so they have opened an increasing distance from other universities.

Beep!

"The Wucheng University of Arts and Sciences successfully passed [Question B], in 11 minutes and 26 seconds!"

The sudden sound of the announcement of the competition committee immediately made Ding Yue excited!

Own Wucheng University of Arts and Sciences!

It was actually the second college team that solved [Question B], which surprised Ding Yue.

The time ranking for the first question is relatively high. This second question is directly second, and it is only 17 seconds away from Imperial College which solved [Question B]. Isn't it a gap?

"Brother Yue, Abin and the others are awesome! Solved this problem so quickly?" Huang Youjie excitedly grabbed Ding Yue's arm after hearing the announcement from the competition committee.

"Hahaha, it seems that Abin really didn't disappoint me. Chen Jun and Ouyang Chen are also good guys."

With such good results, Ding Yue was naturally happy.

Summarizing the time spent on the first question and the second question, perhaps Wucheng University of Arts and Sciences can be among the best?

Then one after another, St. Petersburg State University, California Institute of Technology, Nanyang Technological University, Haicheng Jiaotong University, Moscow State University and other universities have also passed [Question B], and the time spent by everyone is actually the same, the most is one or two. Time interval of minutes.

These are the first echelon participating universities, and they are very strong in all aspects.

As an opponent, we must pay attention to it.

Subsequently, more than a dozen other universities also passed [Subject B], including Northwest University of Science and Technology from Xia Guo.

And this time, the university that was on [Question B] was not only the University of Cape Town from Africa. In addition, there were three other universities that had problems solving [Question B].

In the end, the 30-minute answering time passed, and the four universities failed to get results.

In this way, the University of Cape Town from Africa has completely lost the opportunity to compete for the ACM championship.

Then the other about thirty universities are currently divided into two echelons. The first echelon is St. Petersburg State University, Imperial College, California Institute of Technology, University of California, Berkeley, Haicheng Jiaotong University and other strong universities.

Of course, Ding Yue's Wucheng University of Arts and Sciences is also in the first echelon, and after the two questions have been answered, the results are in the forefront of the first echelon.

The difficulty of this question is greater than that of one question. The competition started from [Question C] and became exciting.

Because when the competition committee released the third question, the participating teams from various colleges and universities were intensively answering the question.

This time, no college solved [Question C] in ten minutes. The most important thing is that the answer time given by the competition committee for this question is actually 45 minutes.

The time to answer a question has increased, which also means that the difficulty of the question has risen sharply.

The University of Cape Town's participating team is not very strong, and when facing [Question C], it is a bit at a loss.

"This program seems to have no solution!"

"Impossible, will the competition committee issue an unsolvable problem?"

"Then you can try to use C language to solve it?"

"Oh, this is too difficult, or impossible at all."

The teams from the lower-ranking colleges and universities were immediately baffled by this [Question C], which was like a stumbling block.

Through this question, the teams with strong computer power and those who are not good at it are completely distinguished.

When facing this problem, the college participating teams in the first echelon did not appear to be embarrassed. Everyone was solving this procedure in an orderly manner.

With the strong support of his two teammates, Xu Bin's programming is also easy to write.

This question is indeed very difficult, but for computer ghosts like Xu Bin, the difficulty is nothing more than the process of writing a program is a little more complicated, not an unsolvable program problem.

Like Xu Bin and the others, the players from the other first-tier college teams are calmly programming to solve this problem.

And the second-tier colleges and universities participating team players, some of them performed well and treated them as calmly as the first-tier colleges and universities.

For others, the three of them started to discuss.

Discussion means that they have no idea to solve the problem in the first time, which is a waste of time.

After all, the ACM International College Student Program Design Competition is about who can solve the program problems given by the competition committee faster and more efficiently.

Twenty minutes passed.

The arena is still very quiet, and there has not yet been the first college team to solve [Question C].

Even Ding Yue couldn't help holding his breath, wondering whether this topic is so difficult?

Basically, after ten minutes had passed for the first two questions, colleges and universities began to solve them one after another. Now this question, twenty minutes later, there is still no movement.

Live Room of Science and Education Channel of National TV Station——

"I am a computer professional, and with all due respect I was dumbfounded by this question."

"Twenty minutes? Still no participating team solves this problem?"

"It's so difficult Yazi."

"This question should be a good opportunity to chase points, Haicheng Jiaotong University rushes!"

"Wizard University of Arts and Sciences!"

"Northwestern University of Science and Technology, give him a punch!"

"It's over, the third question of this ACM competition, I basically can't understand the computer."

"It's really difficult. The problem is very complicated to solve."

"Yes, yes, it's not only complicated, but a little carelessness can cause program errors, which is very difficult."

In the live broadcast room of the Science and Education Channel of National TV Station, there are more than 20,000 viewers from Wucheng University of Arts and Sciences.

This ACM international college student programming competition is very important for Wucheng University of Arts and Sciences.

Because this is the first international competition of Wucheng University of Arts and Sciences, many students of Wucheng University of Arts and Sciences are spontaneously paying attention to the situation of the competition.

Beep!

The scene of the game.

Finally the voice that everyone is familiar with was heard.

"Congratulations to Moscow State University for successfully solving [Question C]. It took 23 minutes and 41 seconds!"

boom!

Following the announcement of the competition committee, behind the three contestants of Moscow State University, an orange balloon marked "FIRST-PROBLEM-SOLVED" rose up.

In fact, the color of each balloon is different.

"It seems that for each of the following questions, it should take more and more time." Ding Yue couldn't help but said with emotion after seeing Moscow State University successfully won the first place in this question.

The time spent on this question has almost doubled compared to the previous question.

"Moscow State University is very strong, and St. Petersburg State University has almost won the ACM competition in recent years!"

Huang Youjie said with a mobile phone in his hand.

He just checked the information and found out that the two universities, Moscow State University and St. Petersburg State University, seem to have won quite a lot in the ACM competitions in recent years.

"I just want to know when Abin will solve this problem!"

Ding Yue's expression became a bit solemn.

If each of the following questions takes a long time, then the variables behind may be relatively large.

For example, St. Petersburg State University, which passed the first question first, has yet to solve this question.

Beep!

"Haicheng Jiaotong University successfully passed [Question C] in 24 minutes and 07 seconds!"

The second one to solve [Question C] was Haicheng Jiaotong University.

It seems worthy of being the most promising university in China, with extraordinary strength and even a chance to compete for the championship.

Beep!

"Imperial College of Technology successfully passed [Question C] in 24 minutes and 29 seconds!"

Beep!

"Wizard University of Arts and Sciences successfully passed [Question C], it took 24 minutes and 33 seconds!"

Soon, two colleges and universities in a row solved the problem within less than five seconds.

One of the universities is Ding Yue's Wucheng University of Arts and Sciences, which is almost better than Imperial College's performance on this topic.

"The difference is not big, the difference is not big, it's okay!" Ding Yue breathed a sigh of relief after hearing his time results on this topic at Wucheng University of Arts and Sciences.

The difference with the first place is only one minute, and this minute has little effect on the following questions.

"President Ding, the results of our Wucheng University of Arts and Sciences on these three questions seem to be pretty good."

Wen Ruohan said happily.

"Well, it's okay." Ding Yue glanced at Wen Ruohan, who was very excited, and said: "You have to stay this way until the game is over, and then other colleges and universities one after another. If this happens, there should be a chance. "

The other universities mentioned by Ding Yue are one after another, meaning that they are like St. Petersburg State University for the first question, California Polytechnic University for the second question, and Moscow State University for the third question, although one question is The first one is solved, but as long as it is a little slower later, then the time score will be leveled.

Instead, like Ding Yue's Wucheng University of Arts and Sciences, the results of each question are relatively high, and the time difference with the first and second places is not big.

Calculated in this way, Ding Yue's Wucheng University of Arts and Sciences may have a lead in time.

However, St. Petersburg State University’s results have always been relatively good, and California Institute of Technology, like Ding Yue’s Wucheng University of Arts and Sciences, has not won the first place, but its results have always been in the forefront.

Sometimes even better than Ding Yue's Wucheng University of Arts and Sciences.

45 minutes passed.

In the end, only 25 colleges and universities passed [Question C]. This time, this stumbling block directly stopped nine colleges and universities. One can imagine how difficult the next question will be.

"Brother Yue, every question behind this will be more difficult?" Huang Youjie, who was sitting next to Ding Yue, couldn't help asking.

"That's for sure. Each of the next questions will kill one university after another. If you don't solve one of the questions, you will basically miss the championship."

Ding Yue nodded and replied.

"Then Abin and the others must not make mistakes!" Huang Youjie suddenly became nervous.

This third question has already stumped nine colleges and universities. Huang Youjie is not nervous.

Ding Yue calmed down Lao Huang's nervousness, and said with a smile: "Lao Huang, let's trust A Bin and the others."

Actually.

Ding Yue said that, but he had no bottom in his heart. I believe it was to believe, but it is really unknown whether it can pass the customs all the way.

By the time the sixth and seventh questions will be difficult to go to heaven?

With the end of the third question, the competition committee soon opened the fourth question.

After all, the total time of the competition is five hours. Although it may be extended for various reasons, too much time should not be wasted between each question, because the longer the interval, the easier it is to make the contestants’ hands warm. The feeling of thought disappeared.

[Question D] is here.

In the competition area of ​​Wucheng University of Arts and Sciences, Xu Bin is sitting in front of the computer, with Chen Jun and Ouyang Chen on the right.

"Director Xu, this is a security loophole completion procedure." After analyzing [Topic D], Chen Jun said to Director Xu Bin: "It seems difficult, we can pass..."

If Chen Jun were to solve this problem alone, I'm afraid Chen Jun would have no idea.

But this is a three-person team, and with Director Xu Bin in charge, Chen Jun is not so worried.

"Security breach?"

Xu Bin couldn't help but look at this question after hearing Chen Jun's words.

Xu Bin likes the security breach program the most.

Xu Bin has been working on a security system since he started studying computer science at Wucheng University of Arts and Sciences.

At present, all the basic network equipment in Wucheng University of Arts and Sciences has a security system, which is independently developed and designed by Xu Bin.

Starting from the fourth question, the three contestants of almost all colleges and universities participating teams were discussing the first time.

That's right!

After seeing the first three questions, many colleges and universities have already begun to write programs to solve the bugs.

As for the fourth question, it is not so easy to complete it in an efficient way.

"If the first three questions are appetizers, then the fourth question begins, and the real difficulty comes."

"It looks like this problem is not very easy to solve."

"It has to be said that the annual problems of the ACM Competition Committee are very difficult. The seven problems that can be solved smoothly are all of the world's top level."

Many audiences who love computer programming at the scene started to talk.

In fact, there are many computer experts in these live audiences. After all, the influence of the ACM competition is quite large.

However, even a computer expert, when facing the fourth problem, has to sigh that this problem is actually quite difficult.

But these computer experts did not say that this problem cannot be solved.

The solution is definitely solvable, it depends on how the participating teams from various universities solve it.

"This security vulnerability looks exaggerated, but in fact it is not very difficult." After reading the question, Xu Bin began to fix the security vulnerability.

The fourth question is to allow participating college teams to fix this security loophole through programs.

Since we want to fix this security hole, we must first understand what the programming code of this security hole is.

This is the first major difficulty for many universities.

But for Xu Bin, a computer genius who has been exposed to countless security vulnerabilities, this does not seem to be difficult.

Soon, Xu Bin found the programming code of this security vulnerability almost immediately.

Then start to repair according to the security vulnerabilities.

The competition committee gave a full hour for this question, which shows that the competition committee has a very high degree of difficulty for this question.

"Director Xu, do you know the programming code of this security hole?" Chen Jun asked in surprise when he saw that Director Xu Bin started to fix the security hole directly.

While others are still analyzing what kind of programming code this security vulnerability is, Director Xu Bin is already on the way to fix it.

This means that Director Xu Bin is a lot ahead of other universities on this question!

"I have been in touch, I have done security systems and tried a lot." Xu Bin said to Chen Jun while fixing the security loopholes: "What a coincidence."

After Chen Jun heard this, he didn't ask any more, because if he asked again, it is estimated that Director Xu Bin's time to fix the security loopholes will be delayed.

For this question, the roles of Chen Jun and Ouyang Chen were relatively smaller all of a sudden, and they basically belonged to Director Xu Bin’s personal show.

Ding Yue felt a little excited when he saw Xu Bin in the backstage lounge as if he was already writing programming code to fix security vulnerabilities.

"It seems that A Bin is determined to win this topic!" Ding Yue said excitedly.

"Really? Huh? Abin is already fixing the security loopholes? Contestants from other colleges and universities are still discussing it!"

Huang Youjie also saw the scene of the game through the screen in the lounge.

The pictures of the 34 colleges and universities participating teams can be seen. Most of the colleges, including St. Petersburg State University and Imperial College of Technology, the three players in the first echelon are still discussing how to fix this security vulnerability.

And Xu Bin of Wucheng University of Arts and Sciences has already begun to repair it. Chen Jun and Ouyang Chen on the side seem to have completed the task, and everything is left to Xu Bin, who is responsible for programming and fixing security vulnerabilities.

Gradually, more people began to pay attention to the contestants of Wucheng University of Arts and Sciences.

The way they are solving this problem seems to be different from other participating universities. After almost no discussion, they started to fix the security loopholes?

After 27 minutes and 30 seconds, the jury team of the competition committee received the "answer sheet" submitted by Wucheng University of Arts and Sciences.

"Did this security hole be fixed so soon?"

One of the judges of the jury group looked at the surrounding colleagues in surprise and asked.

"Let's take a look first, this security vulnerability program, according to past experience, takes nearly forty minutes." Another judge from the judge group said.

Then the judges began to grade the "answer sheet" submitted by Wucheng University of Arts and Sciences on whether it passed.

About three minutes later.

"This... actually fixes the security hole!"

The judges were all surprised!

[Question D] is the only program design question with security vulnerabilities in the ACM competition. The difficulty is naturally very high, otherwise it is impossible to give a full hour to answer the question.

In 27 minutes and 30 seconds, the participating team of Wucheng University of Arts and Sciences has successfully solved and fixed this security vulnerability.

For the judges of the jury group, this is simply incredible!

"Genius, to be able to fix this security hole so quickly, I have to say, this is a real genius!"

A judge named Smeigo couldn't help but said with emotion.

"Pass, announce it!"

The judges of the jury group unanimously determined that the "answer sheet" submitted by Wucheng University of Arts and Sciences has indeed successfully repaired the security loopholes.

Beep!

Just as the participating teams from 33 other colleges and universities were still earnestly fixing the security loopholes, shocking voices sounded.

"Congratulations to Wucheng University of Arts and Sciences for successfully solving [Question D] in 27 minutes and 30 seconds!"

The voice fell.

Immediately with a "bang", behind Xu Bin, Chen Jun and Ouyang Chen, the red balloon that marked "FIRST-PROBLEM-SOLVED" finally rose.

I don’t know if it’s a special design or a coincidence. The balloon that was raised after Wucheng University of Arts and Sciences first solved [Question D] was actually red. Doesn’t this mean the red of the East?

Perhaps this is just a coincidence.

"Principal Ding, the red balloon, Director Xu and the others are great too, they are the first to solve this problem! That's amazing!"

Wen Ruohan was already excited when he saw this.

After all, this is the first time that Wucheng University of Arts and Science has solved a problem first, but Wen Ruohan doesn't know whether 27 minutes and 30 seconds is fast.

In fact, Ding Yue didn't know if it was fast, it would depend on how long it took for the second place to pass [Question D].

Only the judges of the jury group of the competition committee know that the time of 27 minutes and 30 seconds has broken the record in the previous security bug fixes.

"Are they so fast at Wucheng University of Arts and Sciences?"

A contestant from Haicheng Jiaotong University, also a participating university in the Xiaguo Division, exclaimed.

"It's fast enough, it's a bit BT, but don't waste time, hurry up and fix the security loopholes." Another contestant from Haicheng Jiaotong University said quickly.

The contestants of Haicheng Jiaotong University were equally shocked. There are also many universities, such as Saint Petersburg State University, Imperial College of Technology, California Institute of Technology, Moscow State University, etc. Their contestants are also hearing the fog. City University of Arts and Sciences was the first to complete the repair of security vulnerabilities in 27 minutes and 30 seconds, and was dumbfounded.

Some are dumbfounded, some are happy.

The happiest one is naturally Ding Yue.

"Hahahaha, A Bin really doesn't let me down, so I will start to take first place." Ding Yue nodded contentedly.

At the same time, Ding Yue was also calculating silently in his heart, how long would it take before his accumulated time scores from Wucheng University of Arts and Sciences can temporarily rank first?

At present, the cumulative time scores ranked in front of Wucheng University of Arts and Sciences, St. Petersburg State University, Moscow State University, Imperial College of Technology, California Institute of Technology, Haicheng Jiaotong University and University of California at Berkeley.

There are six in total.

Among them, the time difference between Haicheng Jiaotong University and the University of California at Berkeley and Wucheng University of Arts and Sciences is actually less than 30 seconds.

Now, 30 seconds have passed.

However, the two universities still did not solve the problem of this security loophole.

This also means that the current cumulative time score of Wucheng University of Arts and Sciences has surpassed Haicheng Jiaotong University and University of California, Berkeley.

The time gap between the first four universities and the Wucheng University of Arts and Sciences is at least 1 minute, and even Saint Petersburg State University has a time gap of more than 5 minutes with the Wucheng University of Arts and Sciences because it took the first place.

For the next four and a half minutes, Ding Yue's mood was always nervous.

however.

Four and a half minutes passed quickly.

At this time Ding Yue was both pleasantly surprised and puzzled.

what happened?

Why hasn't other universities solved the problem of fixing this security vulnerability?

At this time, even if St. Petersburg State University passed [Topic D], the time score could not surpass the Wucheng University of Arts and Sciences.

The temporary number one has been firmly grasped.

Live Room of Science and Education Channel of National TV Station——

"Hahahaha, our Wucheng University of Arts and Sciences is awesome. It's time to rank first, right?"

"This is great. The problem of fixing security vulnerabilities has been solved so quickly."

"Is it number one?"

"What? Wucheng University of Arts and Science won the championship?"

"Uh uh uh, don't talk nonsense, it's just that the results should be first for the time being. It's hard to say to win the championship. After all, there are three questions behind, and one question is more difficult than the other."

The domestic audience is already boiling.

To everyone's surprise, Wucheng University of Arts and Sciences actually took the lead temporarily. It seems that everyone has underestimated the strength of this university before.

In fact, many people think that going to Wucheng University of Arts and Sciences this time is a part of luck, and it is just soy sauce.

But from the first question to the fourth question now, everyone has seen it. Wucheng University of Arts and Sciences has always performed very well.

Until the fourth question was solved so quickly, it completely changed everyone's view of Wucheng University of Arts and Sciences.

Now, among the three domestic universities participating in the ACM competition, Wucheng University of Arts and Sciences and Haicheng Jiaotong University have been recognized by the audience. Everyone thinks that these two universities have a chance to win the championship.

As for Northwestern University of Science and Technology, it can only be said that there is indeed a slight gap in strength, but Northwestern University of Science and Technology is already quite good in the second echelon.

However, based on the current time results, Northwestern University of Science and Technology basically has no chance of competing for the championship.

Unless at the time of the seventh question, Northwest University of Science and Technology suddenly emerged and solved the problem in super fast time, but this is almost impossible.

As we all know, the seventh question is simply difficult to get to the sky.

35 minutes has passed for the fourth question. Ding Yue took a deep breath and wondered whether it has been 35 minutes. Is there still no other colleges and universities to fix the security vulnerabilities?

This!

It's so cool!

Because the later time, it means that his Wucheng University of Arts and Sciences will have a greater advantage on this topic.

Beep!

Finally, after another minute or so, there was a beep.

Then the competition committee announced: "Imperial College of Technology successfully passed [Question D], it took 36 minutes and 49 seconds!"

Beep!

"St Petersburg State University successfully passed [Question D] in 37 minutes and 01 seconds!"

Beep!

"California Institute of Technology successfully passed [Question D] in 37 minutes and 55 seconds!"

Beep!

"Haicheng Jiaotong University successfully passed [Question D] in 38 minutes and 44 seconds!"

Starting from the successful repair of security vulnerabilities by Imperial College London, the successive first-tier universities have also been successfully completed.

The gap between everyone is not big, but compared with Wucheng University of Arts and Sciences, the gap is big.

The time for this question is nearly ten minutes short!

St. Petersburg State University is a bit awesome. This question is less than ten minutes away, plus his five-minute advantage.

This means that between St. Petersburg State University and Wucheng University of Arts and Sciences, there is actually a difference of about three or four minutes.

Ding Yue remembered this St. Petersburg State University, and it was his biggest competitor of Wucheng University of Arts and Sciences on the road to winning.

Of course, in fact, the strong universities such as Imperial College, Haicheng Jiaotong University and California Institute of Technology should not be underestimated.

The fourth question suddenly changed the results on the field.

Some colleges and universities that were originally in the first echelon fell directly to the second echelon because of this security bug fix.

Some colleges and universities in the second echelon, because it took more than forty minutes to solve the security vulnerabilities, have been among the first echelon.

But the college teams at the end of the crane are basically the same, and the dishes are still dishes.

Especially from the University of Cape Town in Africa, they failed [Question D] again.

It seems that every question is difficult for the three contestants of the University of Cape Town participating team. I don’t know how their alumni feel when they see the competition?

After the fourth question is over, who has a chance to win the championship, who is only here to play soy sauce, it is all clear at a glance.

The fifth question seems not as difficult as imagined.

Moreover, the fifth problem solving time given by the competition committee was only 20 minutes, which was the shortest problem solving time.

however!

The short time of the fifth question does not mean that it is not difficult.

It is because this problem does not require many programs, but it is really difficult. Many second-tier universities have racked their brains and still don't know how to solve this program problem.

The top universities in the first echelon are still very calm.

It seems that even the fifth question can't help them.

With the perfect cooperation of Chen Jun and Ouyang Chen, Xu Bin used 11 minutes and 27 seconds to pass the question in the third place.

The time gap between the top two and Wucheng University of Arts and Sciences is only one minute at most.

This means that although the fifth question, Wucheng University of Arts and Sciences is not the first to solve, but the current cumulative time results, Wucheng University of Arts and Sciences is temporarily ranked first.

"If this can be stabilized, it seems that we have a chance to win the championship!" Huang Youjie looked at the cumulative time results after the fifth question was about to end.

Wucheng University of Arts and Sciences temporarily ranked first, St. Petersburg State University second, Imperial College of Technology third, California Institute of Technology fourth, Moscow State University fifth, Haicheng Jiaotong University sixth, Nanyang Technological University seventh, University of California Berkeley Eighth, ETH Zurich is ninth and Stanford University is tenth.

Speaking of which, Stanford University is a super well-known world-class university in Yingjiang Country. It also ranks among the top in the global rankings, and sometimes even in the top three.

but!

In the ACM competition, Stanford University’s performance is not very good. It may be that the strength of their three participating teams is indeed a certain gap compared to the previous universities.

It seems that the favorites to win the championship are obviously colleges and universities in the top ten.

Ding Yue was expecting that just as Huang said, as long as his Wucheng University of Arts and Sciences is steady, will the championship be readily available soon?

But the sixth and seventh questions are coming soon, whether this can be stabilized, it really has to be a big question mark.

If you can win the championship, you can make a blockbuster, at least in the field of computer science.

If you can't win the championship, even if you shine in the fourth question, it is useless, because in the end people only pay attention to the championship.

"call."

Ding Yue let out a long breath, and then said to Lao Huang, "I hope Abin and the others can stabilize it. Of course, it would be great to be able to create another grade like the fourth question."

"Yes!"

While Ding Yue and Huang Youjie were chatting, the competition committee announced that the sixth question had started.

[Question F] The difficulty is directly full, and it takes an hour to answer the question, of course, the time set by the competition committee at this time.

That is, the question [Question F] must be solved within one hour, otherwise this question will be considered as a failure, and if it is not passed, this question will not be scored.

For those college teams that have the opportunity to compete for the championship, if this question fails to get results, then go directly to GG.

The difficulty of the sixth question exceeded the expectations of many universities.

"This...this is almost impossible to accomplish!"

"too difficult!"

"One hour? I spend a day, but I may not be able to do it!"

"Mike, start now!"

"Hurry up, hurry up and try it out!"

Many students from well-known universities were a little discouraged after seeing the sixth question.

In fact, even Xu Bin frowned.

Chen Jun and Ouyang Chen on the side were also very worried.

"Director Xu, this question just depends on the analysis of me and Ouyang Chen, I am afraid it will not work." Chen Jun said to Director Xu seriously.

"I know, but it doesn't matter. Let's try to solve this problem together. You can provide ideas as much as possible."

Although Xu Bin frowned, he did not panic.

Because he knew that he had to calm down at this time, and once he got confused, it would really be impossible to solve this problem in an hour.

It is said that there are three heads, the best Zhuge Liang.

What's more, Xu Bin, Chen Jun and Ouyang Chen are not heads, but talented college students majoring in computer science.

Three people work together, maybe it's really amazing.

Xu Bin is a computer major, because he is very hobby and has good abilities. In addition, during the more than one year at Wucheng University of Arts and Sciences, he also has the bonus of studying BUFF, as well as the various benefits given by Ding Yue. Kind of small plug-in.

When Xu Bin faced the problems of the ACM competition, he did not say that he had no absolute certainty, but he did not have any confidence.

However, unlike Xu Bin, the students from other universities are a little depressed.

They did not have too much pressure to solve the first five questions, and at most the fourth question took more time.

But for the sixth question, some students have even begun to feel a little depressed.

"I don't think we can solve this program within an hour!" Wilk from the University of California at Berkeley sighed.

"Hey, Wilk, we have to build up confidence!" Wilk's teammate said encouragingly.

"but......"

It can be seen that even the participating teams at the University of California, Berkeley are already on the verge of collapse in answering questions.

This is currently the top ten universities in terms of performance!

It is conceivable how desperate other colleges and universities, and even the second-tier college participating teams, were when faced with the sixth question.

At this time, the mentality is very important.

Xu Bin, Chen Jun, and Ouyang Chen from Wucheng University of Arts and Sciences analyzed this [topic G] in an orderly manner.

Finally, Xu Bin has an idea.

"Look, is it okay to try to solve it this way?" Xu Bin asked Chen Jun and Ouyang Chen while operating.

The two took a closer look and were not quite sure, but they both nodded and said in unison: "Director Xu, I think I can try it!"

"it is good!"

Xu Bin took a deep breath and thought of what his good brother principal Ding Yue expects of him, so he gritted his teeth and began to try to solve [Question G].

Even if this method does not work, Xu Bin thought that there should be a chance to change the solution.

But this method must be tried.

The competition committee received the "answer sheet" submitted by Imperial College London in 31 minutes.

however!

The result given by the judges is-WA!

That means the answer is wrong!

According to the answering rules of the ACM competition, if the program submitted within the specified time does not run correctly, the program will be returned to the team, and the team can make changes and submit the question again.

In other words, all participating universities have the opportunity to consciously try and error.

Obviously, Imperial College is making a bet on the fact that the program they submitted for the first time will pass.

Once it can pass, it is estimated that it can lead by a large margin.

Because of this problem, if everyone feels that it can be solved, it will take at least 50 minutes to go up.

Beep!

"Imperial College of Technology submitted the wrong answer!"

The competition committee returned the procedure of Imperial College London, and the three contestants of Imperial College London were directly confused.

"It's over."

"There are twenty minutes left, let's try plan B?"

"That's all, hurry up."

After the three of them were frustrated, they quickly adjusted their status. If plan A was running incorrectly, then only plan B could be executed.

Like Imperial College of Technology, Moscow State University also chooses the two options AB for trial and error.

Almost exactly the same, after the Moscow State University’s A plan was submitted, it was rated as WA!

Immediately returned to Moscow State University, they immediately began to carry out the B plan.

But time is already very short, and plan B may not have a chance to be fully realized.

In fact, Xu Bin from Wucheng University of Arts and Sciences also implemented the same methods as Imperial College of Technology and Moscow State University.

That is to try it first, and if it is wrong, try another solution.

But when Xu Bin was writing the program, he found that there seemed to be no problem with this idea. With the assistance of Chen Jun and Ouyang Chen on the sidelines, Xu Bin now just wants to perfect and perfect the current answering method as soon as possible!

"Brother Yue, several colleges and universities have submitted programs, but they are all wrong. This is trial and error? But how did I find that Abin and the others didn't mean to be prepared for trial and error?"

Huang Youjie saw the difference and asked Ding Yue curiously.

"The best way to do this question is to make trial and error. If Abin and the others are not prepared to use this method, it can only show one problem."

Ding Yue said, a smile suddenly appeared at the corner of his mouth.

"What's the problem?" Old Huang couldn't wait to ask.

"That is Abin and the others are confident to solve [Question G] directly at once!"

During the 30 minutes to 45 minutes of solving the problem, colleges and universities kept submitting answers, but all the replies received by the judges were-wrong answers!

In other words, the way they tried to fight for trial and error in a short time was basically wrong.

As a result, many colleges and universities have almost given up on this question.

Because there are still twenty minutes or ten minutes left, it is almost impossible to run the program of the second program perfectly.

Of course, there are also some great college teams that are confident, such as Imperial College London and Haicheng Jiaotong University.

At 53 minutes.

Xu Bin finished typing the last line of code, and then looked at Chen Jun and Ouyang Chen.

The two nodded together.

Once this is submitted, it is fine if it passes. If it fails, it will be a bit miserable, and it may even lose the chance to compete for the championship.

After all, if the program fails to run after submitting it, there will still be seven minutes left. If you change it to another method, it will be too late.

Seeing the two of them, Xu Bin's eyes were firm, and his heart was stunned!

submit!

About half a minute passed.

Beep!

"Congratulations to Wucheng University of Arts and Sciences for successfully solving [Question G]. It took 53 minutes!"

boom!

With the purple balloon rising from behind Xu Bin, Chen Jun and Ouyang Chen, the first college to solve the sixth problem was born.

Wucheng University of Arts and Sciences!

The audience even burst into applause.

Because it has been 53 minutes, finally the first college successfully solved [Question G].

It can be seen that this question is really difficult.

Of the 30 or so colleges and universities, at least ten have already given up.

There are also about ten colleges and universities participating in the team feel that it is too late.

Some of the remaining ones are trying to miss one time, and some are going on the second time, and some are walking down to the dark like Wucheng University of Arts and Sciences.

Beep!

"California Institute of Technology successfully passed [Question G] in 55 minutes and 09 seconds!"

In fifty-five minutes, California Institute of Technology also solved this huge problem.

In the next five minutes, Imperial College submitted the second answer and passed, and Haicheng Jiaotong University passed it in 58 minutes.

St Petersburg University passed in 59 minutes.

The answer sheet submitted by Moscow State University-wrong!

This is all right now, Moscow State University is directly cool, and this sixth question did not get results.

Nanyang Technological University actually passed [Question F] on the timeline.

The sixth question directly kicked other participating universities out of the championship battle.

In other words, the championship can basically only be born from Wucheng University of Arts and Sciences, Imperial College of Technology, Saint Petersburg State University, Haicheng Jiaotong University, California Institute of Technology, and Nanyang Technological University.

However, Nanyang Technological University has a relatively poor cumulative time score before, so it is not generally difficult to compete for the championship.

At this moment, Ding Yue's heart had already touched his throat.

The last question will determine the winner!

The competition committee announced the seventh question!

The difficulty of the seventh question, after the other college participating teams met, they were not interested in solving the problem.

Because of this difficulty, it is even more difficult than the sixth question.

If this program can be completed, I am afraid that there is no problem in going to any computer company in the world as the chief engineer of computer program, right?

The three contestants from Haicheng Jiaotong University had that expression on their faces after seeing the seventh question.

"Gan! This...Although it has been given an hour and a half, how can this be done?"

"Nima, give me a month, I may not be able to solve it."

"This year's ACM contest topic is too BT, right?"

The three young boys are a little desperate.

After a while, one of them calmed down and said, "Maybe there are other shortcuts to solve this program, otherwise, how could the competition committee allow us to solve this program in one month and a half? program!"

"It makes sense!"

At Wucheng University of Arts and Sciences, Xu Bin, Chen Jun, and Ouyang Chen are analyzing this question.

[Question G] It's really difficult.

After meeting Ouyang Chen, he was dumbfounded.

Chen Jun is a little better and can barely analyze it.

Xu Bin's brows kept frowning, because he also felt that it seemed impossible to complete this topic.

But when you think about it carefully, this shouldn't be.

How can the competition committee come up with a problem that almost everyone can't complete?

"Yes!"

At this moment, the idea of ​​genius is always different from others.

"Director Xu, do you have ideas?" Chen Jun widened his eyes and asked Xu Bin.

At this moment.

On the side of St. Petersburg State University, the three players are calm.

The three contestants of Imperial College London were in heated discussions.

These players are all called geniuses. They don't actually come to participate in the ACM competition, and rely on their school results to easily work in any of the world's top computer companies.

Even among them, there is no shortage of experts in the hacker circle.

For example, a player from Imperial College London is a master in the global hacker community, code-named "Mediterranean".

The game scene fell into a long period of silence.

Because the problem-solving time of the seventh problem is as long as one and a half hours.

In the first hour, none of the participating college teams submitted answers.

One hour and twenty minutes.

Still not!

At one hour and twenty-two minutes, there was finally movement on the court!

Beep!

"Congratulations..."

When Ding Yue heard the words congratulations, his pupils suddenly tightened.

Because he knew that the college team that solved the seventh question was born, and the champion is very likely to be born like this!
