Rule system

The Olympiad is coming.

Only Sun Liang and Zhao Yi entered the province to participate in the thirteenth high school entrance examination. Niu Lianhua attaches great importance to the Olympiad. When doing questions, Sun Liang and Zhao Yi have good performances and their ability to solve problems is better than her less.

Niu Lianhua can't teach much, but she can help buy reference books and supervise them to do the questions.

Whenever it’s noon, Niu Lianhua will come to see if Sun Liang and Zhao Yi will do Mathematical Olympiad again, and give them a few classic questions from the past, and urge them to finish them. understand.

Zhao Yi also attaches great importance to the Olympiad.

If you can get a first prize in the province, you can add 20 points to the college entrance examination. For students who can get more than 600 points in the exam, 20 points are enough to determine whether they are admitted to the top universities.

This may be an unfair part of the college entrance examination.

Of course.

Zhao Yi is temporarily unable to change the unfairness, so he can only let himself adapt, and it is best to stand in a favorable position.

Today Niu Lianhua is here again.

She held the reference book in her hand, printed a few test questions, and handed the paper to Zhao Yi.

Sun Liang is not in the classroom.

"Where is Sun Liang?" Niu Lianhua frowned slightly dissatisfied.

"do not know."

"He wasn't with you at noon?"

Zhao Yi said, "We went to the meal on the street opposite the school. I came back after eating. He, I didn't pay attention and didn't know what to do." He also thought it was a bit strange. Normally Sun Liang should have returned long ago.

Niu Lianhua nodded and went out.

Maybe it was to switch to Sun Liang, maybe it was just to go back to the office, or some other place to rest.

When Zhao Yi was preparing to do the question, he heard Zhao Linlin say sourly, "I feel that you and Sun Liang have kissed more than me and her. Now she is your aunt, no, mother."

Lin Xiaoqing smiled'pounce', she leaned sideways and said, "Linlin, don't be sour, Teacher Niu just values ​​competition."

"I know too!"

Zhao Linlin sighed, "She has been teaching for so many years, but no student has ever won an Olympiad prize, so she must pay attention to it."

"You are hypocritical!"

Zhao Yi said with disdain, "I said before that Teacher Niu takes care of everything. It doesn't matter what you are, you are still sour."

"Yeah! Don't you want this?" Lin Xiaoqing followed, "I don't know who always said,'I really hope Aunt Niu doesn't care about me.' Your grades have improved, and Teacher Niu no longer forces you to go to physics at noon. Up."

"Or do you want to continue tuition?" Zhao Yi followed.

"Let Teacher Niu supervise your study twenty-four hours?" Lin Xiaoqing continued to follow.

Zhao Linlin looked at Lin Xiaoqing, then turned her head to look at Zhao Yi, scratching her hair depressedly, "You!"

She gritted her teeth, "Why are you more and more like couples!"

"Damn!"

Lin Xiaoqing gave a light mouth, blushing anxiously, "What are you talking about!"

"It was originally."

Zhao Linlin found a breakthrough in the counterattack, and her smile couldn't close her mouth. "Look, it's a sentence for each person. The husband sings and the wife follows!"

"Don't talk nonsense!"

"I didn't talk nonsense!"

"You are like a couple with him!"

"Really?" Zhao Linlin smiled carelessly, "Or you can give him to me!"

"Take it!"

"Cut, I don't want it!"

"Send you off!"

"Smelly, I'll give it to you!"

Zhao Yi listened happily at first, but later found that something was getting worse and worse. Why did he seem to have become a lump...cough cough, why do you want to be disgusted by all kinds of things?

When the two girls were laughing, Sun Liang quickly ran in from the door, and shouted proudly, "I just made fifty yuan!"

Several people looked over.

Sun Liang rushed to Zhao Yi and said excitedly, "There was a policeman who didn't know what he was doing. He asked other people at the door to ask me. I was shocked and went over to ask something. Guess, what's wrong with him?"

"You said it."

Zhao Yi's indifferent tone was a bit shocking.

Sun Liang didn’t care at all, and continued to say excitedly, “He actually asked me to do math problems! It’s really a math problem, or a problem that I just did. Last week, remember? That set of math papers was very difficult for the last one. ..."

"He said that I would help make it, so he would pay."

"One opening is twenty!"

"I thought he was joking again, so he just said fifty lines? He actually agreed. This is the first time I have encountered such a good thing. After finishing the questions, he really gave me two hundred!"

"Remember, when you ask me questions in the future, it costs at least...5 yuan! One discount!"

Sun Liang talked about taking out the red ticket in his pocket, and strangely found that several people's reactions were a bit wrong, "What's wrong with you?"

The three of Zhao Yi glanced at each other.

Lin Xiaoqing couldn't help being the first to laugh, covering her mouth, and then she simply covered her belly and shook her shoulders.

Zhao Linlin also laughed.

Zhao Yi took a deep breath and smiled and said to Sun Liang, "If someone finds you tomorrow, you will have five hundred!"

"Don't do it for less than five hundred!"

"By the way, this is the paper that Teacher Niu brought. Here, the questions on it are quite difficult..."

...

Went home that night.

Zhao Yi quickly entered the working state and made the final revisions to the paper. When the revisions were almost done, he passed a copy to Professor Liu and asked Professor Liu to help it.

Professor Liu quickly replied, "You can directly submit the manuscript. I said hello to Kamani, and she will review the manuscript for you in these two days. It doesn't matter if there are minor errors in the format, she will help you modify, Perfect it."

Professor Liu added, "This is also the job of reviewers and editors."

real or fake?

How good is the review editor of Journal-of-the-ACM?How about perfecting the format of submissions?

Zhao Yi always felt that something was wrong, so he simply searched the Internet and found the introduction of a'Kamanni'.

Shirley Camany.

Doctor of Biology, Doctor of Informatics, Professor of Oxford University, Editor of "Journal-of-the-ACM"...

The important thing is, the female editor?

Age 57?

Zhao Yinao added'Professor Liu and Professor Kamani, the pure friendship established by academic exchanges when they were young', and then simply shook his head and found that he shouldn't be too bad.

Be respectful!

Don't think too much!

After finishing the thesis, he thought of the police website, as if the invasion was suppressed again.

Zhao Yi entered the management portal website and was prompted to "enter the wrong link".

"Changed the entrance?"

He opened the police website again and opened the source code mode to browse the information. The file names of the management portals of some websites were affixed to the root directory of the webpage.

Zhao Yi found several file names, but they were not the management portal.

This is a bit troublesome!

The other party intentionally hides the management entrance, and it is not easy to find the management entrance.

Zhao Yi opened the routing monitoring record. There are many access links to the police website. However, because of the security performance of the routing and browser, it is like the chat message of Penguin. Most of the suffixes are hidden. He wants to decipher garbled codes. impossible.

"Find a way!"

Zhao Yi thought about opening the shared files of the'Red Peach Alliance' group. Most of the content is basic, but some introductions to the hacked websites might bring some inspiration?

He watched carefully.

After watching patiently for a period of time, Zhao Yi found an introduction of "forged routing information". By constructing data packets between the source host and the destination host, the attack of sensitive information on the target host was realized.

He suddenly got inspiration, "Can you copy the information?"

"Fake a data packet with copy function, copy the information sent by the target host, and then send it to my computer?"

Zhao Yi thought and his eyes lit up.

Do it!

Try it!
