Genius of the Rules-Style System

The Mathematical Olympiad is coming.

Only Sun Liang and Zhao Yi were admitted to the provincial competition in the No. 13 Middle School. Niu Lianhua attached great importance to the Mathematical Olympiad competition. When solving problems, Sun Liang and Zhao Yi performed well, and their problem-solving ability was much better than hers. few.

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

Whenever it's noon, Niu Lianhua will come to see if Sun Liang and Zhao Yi are doing Mathematical Olympiad questions again, give them a few classic questions from the past, and urge them to finish them, even if they can't solve them, they must solve them. clear.

Zhao Yi also attaches great importance to the Mathematical Olympiad competition.

If you can go to the province and get a first prize, you can add twenty points to the college entrance examination. For students who can score above 600 points, twenty points are enough to determine whether they are admitted to a top university.

Today the cow lotus is here again.

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

Sun Liang was not in the classroom.

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

"have no idea."

"He wasn't with you at noon?"

Zhao Yidao said, "We went to eat on the street across from the school. I came back after eating. I didn't pay attention to him. I don't know what he was doing." He also felt a little strange. Normally Sun Liang should have come back long ago.

Niulianhua nodded and went out.

Maybe he was looking for Sun Liang, maybe he was going back to the office, or somewhere else to rest.

When Zhao Yi was about to answer the question, he heard Zhao Linlin say with a sour voice, "I feel that you and Sun Liang are closer than me and her. Now she is your biological aunt, no, biological mother."

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

"I know it too!"

Zhao Linlin sighed, "She has taught for so many years, but she has never had a student win an Olympiad award. She must take it seriously."

"You are just hypocritical!"

Zhao Yi said disdainfully, "You were the one who said Teacher Niu was in charge of everything before. If I don't care about you, I'm still sore."

"Yes! Isn't that what you want?" 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 take physics classes at noon. ”

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

"Let Teacher Niu supervise your study 24 hours a day?" Lin Xiaoqing continued to follow.

Zhao Linlin looked at Lin Xiaoqing, then turned to look at Zhao Yi, grabbing her hair in frustration, "You guys!"

She gritted her teeth and said, "Why are you becoming more and more like a couple!"

"oops!"

Lin Xiaoqing spat lightly and suddenly blushed, "What are you talking about!"

"That's what it is."

Zhao Linlin found a breakthrough to counterattack, and she couldn't close her mouth with laughter, "Look, one person only said one word. The husband sang and the wife followed!"

"Stop talking nonsense!"

"I didn't say anything nonsense!"

"You and he are just like a couple!"

"Really?" Zhao Linlin smiled nonchalantly, "How about you just give him to me!"

"Take it!"

"Tch, I don't want it!"

"Give it to you!"

"It stinks so much, I'll give it to you!"

Zhao Yi listened happily at first, but then he realized that something was getting worse and worse. Why did he seem to be like a lump... Ahem, why do you want to be disliked in all kinds of ways?

While the two girls were laughing and joking, Sun Liang ran in from the door quickly, shouting 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 about me at the door. I was startled and went over to ask what was going on. Guess what happened to him?"

"Just say it."

Zhao Yi's nonchalant tone was a bit shocking.

Sun Liang didn't care at all, and continued to say excitedly, "He actually asked me to do a math problem! It was really a math problem, and it was a problem that I had just done last week, remember? That math paper, the last question was particularly difficult …”

"He said he would give me money if I helped make it."

"Twenty as soon as I opened my mouth!"

"I thought he was joking again, so would he just say fifty? He actually agreed. This was the first time I encountered such a good thing. After finishing the questions, he actually gave me fifty!"

"Remember, if you ask me questions in the future, each question will cost at least...five yuan! 10% off!"

Sun Liang took out the red ticket in his pocket as he spoke, and found something strange in the reactions of several people, "What's wrong with you?"

Zhao Yi and the other two looked at each other.

Lin Xiaoqing was the first to hold back, covering her mouth and burst out laughing, then she simply covered her stomach and shook her shoulders.

Zhao Linlin also laughed.

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

"Don't do it if it's less than five hundred!"

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

…

Went home that night.

Zhao Yi quickly got into work mode and made the final revisions to the paper. When the revisions were almost completed, he sent a copy to Professor Liu for help.

Professor Liu quickly replied, "You can just submit your manuscript. I have already said hello to Kamani, and she will review it for you in the next two days. It doesn't matter if there are small errors in the format, she will help you revise it. Perfect it.”

After Professor Liu finished speaking, he added, “This is also the job of the review editor.”

real or fake?

Are the review editors of "Journal-of-the-ACM" so good? Will they even improve the format of the submission?

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

Shirley Kamani.

PhD in biology, PhD in informatics, professor at Oxford University, editor of "Journal-of-the-ACM"...

Importantly, female editor?

Age 57?

Zhao Yi thought about the pure friendship established by Professor Liu and Professor Kamani through academic exchanges when they were young. Later, he simply shook his head and realized that he was really wrong.

Be respectful!

Don't think too much!

After finishing the paper work, he remembered the police website, as if the intrusion matter had been suppressed again.

Zhao Yi entered the management portal URL and was prompted, ‘The wrong link was entered’.

"Changed the entrance?"

He opened the police website again, opened the source code mode and browsed the information. The file names of the management portals of some websites were located in the root directory of the web page.

Zhao Yi found several file names, but they were not the management entrances after trying them.

This is a bit troublesome!

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

Zhao Yi opened the routing monitoring record, which contained many access links to the police website. However, due to the security features of routing and browsers, just like Penguin chat messages, most of the suffixes were hidden, making it almost impossible to decipher the garbled code. impossible.

"Look for a way!"

Zhao Yi thought about it and opened the shared files of the 'Heart Alliance' group. Most of the contents were basic, but some introduction to the intrusion website might bring some inspiration?

He watched carefully.

After patiently watching for a period of time, Zhao Yi discovered an introduction to "fake routing information". By constructing data packets from the source host and the destination host, sensitive information can be used to attack the target host.

He suddenly had an idea, "Can you copy the information?"

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

Zhao Yi's eyes lit up as he thought about it.

Do it!

Give it a try!
