A genius? I just love studying.

Chapter 75 Fools are blessed

Dadi Internet Cafe,

At half past nine in the morning,
Seeing the title of the sixth question, Chen Hui breathed a sigh of relief.

The first question is so simple that even Liang Peixuan can answer it.

After writing the recursive formula, let n tend to infinity and you can get the answer 1/2.

He thought the following questions would be as difficult as the fifth one.

The sixth question is about probability theory. The second question is indeed a bit difficult, but you just need to figure out how to calculate the result step by step.

Because the answer is actually very easy to guess. The five blessings added together are an even number, and the degree of freedom is 4. The probability of each blessing being an even number is 1/2, and the degree of freedom is 4, so the final answer must be 4/2 to the fourth power.

Generally speaking, if there are k blessings, the probability should be one in 2k-1.

To calculate the final result, you need to start from 2 blessings, 3 blessings, 4 blessings and up to 5 blessings.

The reasoning process in the middle requires some summation and scaling, which are all very simple techniques.

Chen Hui rigorously found the answer in less than twenty minutes.

Question 7 is long and boring. The general meaning is that there is a flower tree on a rotating disc.

If one of the young lovers comes under the flower tree, the other will wait there. If the other person can come under the tree within a period of time, they can have a happy meeting.

If not, the person waiting under the tree will leave.

Then ask, if you repeat this process, how can you prove that there is a high probability that the two people will meet each other in the end, and what is the approximate maximum waiting time?

This problem only requires constructing a reasonable h(phi) function, and then turning it into a fixed point law of compression of all things to prove that they will definitely meet.

Then use this to estimate the time of their next encounter.

This question is not easy to answer, but Chen Hui happened to have learned about this subject.

With extraordinary insight, the constructor seems to be a natural thing and is not too difficult.

Eleven forty-eight.

Chen Hui clicked on the next question, only to find that there was no next question.

Looking back, I missed one question worth 20 points, but I finished the rest. Even if some points were deducted during the test, I should have at least 90-100 points, so I should have no problem entering the finals.

Chen Hui stretched lazily, feeling relaxed.

He had originally prepared to work hard all night, but he didn't expect to finish it in just one morning.

Well, it does feel a bit unsatisfied.

As for the fifth question, he didn't plan to spend too much time on it, even though he still had more than a day left in the exam.

One minute on stage, ten years off the stage.

You can’t study on stage for ten years, right?

In the final, he plans to choose the algebra and number theory track. Zhang Anguo said that he has a talent far beyond ordinary people in this area.

He didn't really believe it before, but after finishing this set of questions, he began to believe it a little.

Zhang Anguo may have some personal moral problems, but he does have some knowledge of mathematics and has some vision.

If Zhang Anguo had not reminded him, he probably would not have looked at Lie groups and Lie algebras, and the fourth question would have taken him several hours.

The study path he arranged was very reasonable, at least, very suitable for this exam, which was one of the reasons why Chen Hui was able to finish this set of test papers so quickly.

Therefore, Chen Hui plans to listen to Zhang Anguo's advice and choose the algebra and number theory track for the final.

The fifth question in the preliminary round did not involve knowledge in this direction, and Chen Hui did not plan to study it in depth in the short term.

With this time, he would certainly study more knowledge in algebra and number theory.

Zhang Anguo had already made arrangements for him. Next, he had to seize the time to study commutative algebra, homological algebra, categorical algebra, and algebraic topology...

There’s a long way to go!
Don't hesitate any longer and submit your test paper.

Chen Hui simply read the pop-up reminder once and ignored it, clicking OK directly.

Then shut down your computer.

After he stood up, he realized that there was a circle of people standing behind him.

"Teacher An, when did you come here?"

While he was doing the questions, he vaguely felt some movement behind him, but he didn't expect that the teachers and principals had not left.

Did Teacher Zhang also mention that he was taking an exam here when he asked for leave for him?

An Chengzhang and the other two were stunned and didn't know how to describe the shock in their hearts.

Chen Hui finished the six questions in less than four hours out of the 48-hour exam time!

What kind of monster is this?

Woo...woo...

The vibration of Wu Huachun's phone was very noticeable in the quiet internet cafe. It was Xiao Feng calling.

"Principal Wu, the room you mentioned is ready. We have the highest-spec computers, and the broadband is 2 gigabits..."

Xiao Feng gave a detailed introduction on the phone.

Wu Huachun didn't have the patience to listen to him finish and interrupted him directly, "Okay, I understand. Thank you for your hard work."

An Chengzhang also felt sorry for Xiao Feng. It was obvious that Xiao Feng had put a lot of thought into preparing these things so quickly and to such a high standard.

But who would have thought that the room was ready, but Chen Hui had already finished the questions.

Competing with math experts from all over the world and finishing 48 hours' worth of questions in just four hours, Zhao Defeng didn't know how to describe his feelings at that moment.

He already regarded Chen Hui as a genius, but this little guy still exceeded his understanding time and time again.

Wu Huachun was, after all, a seasoned veteran. He was the first to react and reminded Chen Hui, "Next time, if something like this happens, you should ask for leave from school, otherwise everyone will be worried."

"Didn't Teacher Zhang ask for leave for me?"

Chen Hui was a little confused. He had already told Zhang Anguo about it.

Zhao Defeng and the other two suddenly realized, "This damn Zhang Anguo is not reliable at all!"

"Let's go back to school first."

Wu Huachun said, no matter what, let's wait until the preliminary results come out before making a decision.

"Potato chips and twice-cooked pork rice is here!"

A sudden voice came from outside the Internet cafe, and Li Hai appeared at the door carrying two lunch boxes.

Then, he saw the principal, vice principal, and head teacher all staring at him...

"that……"

Li Hai stuttered, not knowing whether to go forward or backward. He had originally planned to kill time outside and come back to continue playing games after Teacher An left.

But he never expected that Teacher An had been standing behind Chen Hui for the entire morning and hadn't gone back yet.

That would be fine, not only did Teacher An not go back, but the two principals were still there.

You are the principal!
The principal is so busy!

Don't you have anything to do?
Now that’s good, I’m afraid I’ll have to call the parents.

After hesitating for a long time, he made up his mind and continued to move forward. He would die anyway, so Li Hai was not a coward!

"Come on, come on, eat quickly. Even the God of Hell won't accept hungry ghosts. Only when you're full can you have the energy to do the homework!"

Now he only hopes that the teacher will give him a lighter punishment in consideration of his hard work.

However, as soon as he said this, he found that the teachers looked at him even more strangely.

Chen Hui smelled the aroma of twice-cooked pork with potatoes, his appetite increased and his stomach started to growl. His brain had been active all morning, and he was indeed hungry.

What's more, it was his favorite twice-cooked pork with potato chips.

This is a hidden dish of the stir-fry restaurant outside the school. If the owner wasn't Li Hai's third uncle, they wouldn't have had the chance to eat it.

He took the lunch box from Li Hai's hand, sat down again, opened the lunch box, and started to eat like a hungry ghost.

After taking two bites, he turned back to look at Teacher An and asked, "Teacher An, are you hungry?"

An Chengzhang smiled helplessly. He could understand what Chen Hui meant.

This is to protect the fool sitting next to him.

"Let's go back to school."

Wu Huachun didn't say anything more, but just looked at Li Hai again before leaving.

He really couldn't understand how this guy could become Chen Hui's friend.

All I can say is that fools have good luck!

After dinner, Chen Hui gathered up the leftovers, threw them into the trash can, and said to Li Hai, who was about to start working on his computer, "Let's go back to school!"

"what?"

Li Hai, wearing headphones, looked back blankly, "Going back to school already?"

"No more exams?"

"The exam is over!"

"? Didn't you say it would take two days and one night?"

He was prepared to work all night to gain points, but this is the result?
