Chapter 102: Xiaoxi is eager to protect her husband (33, plus more)
Just by reading the question, Chen Xiaoxin knew the solution to this problem. This question is also quite legendary. It was designed by teachers of the national training team and foreign experts. Its quality is probably as difficult as the finale question on the first day of the International Mathematical Competition.

If you can't solve a problem like this, you basically will never be able to solve it in your lifetime, and this is the cruelty of mathematics.

The reverse Pascal's triangle is quite interesting!
If I remember correctly, there was a similar anti-Pascal's triangle at the IMO six years ago. In fact, this question is very easy to understand. Just start from the top and choose the direction where the numbers get bigger each time until you reach the correct path. Of course, how to take the right path and how to digest those big numbers are the essence of this problem.

Chen Xiaoxin's brain began to work rapidly. He imagined countless problem-solving processes in his mind. At the same time, his body's fatigue level was increasing rapidly. In just over ten seconds, he found the most correct path and reversed the calculation process.

Nice!

This is it!
Chen Xiaoxin picked up the pen and frantically solved the problem on the white paper. At this moment, he was already the most handsome guy in the whole audience. In fact, he did not need to overclock his brain. He could prove the correct answer to this question through continuous deduction. It just took a little time, about four minutes.

but,

With the skill of overclocking the brain, the time is greatly reduced. Only two minutes is enough, and these two minutes include the time for thinking.

shhhhh--

The friction between the pen tip and the white paper sounded like the fighting sound of two armies, and it was so pleasant to the ear.

Chen Xiaoxin is like a top-notch Taoist demon-slayer, fighting passionately with the sexy and charming Ti demon. Of course, under his powerful offensive, the little Ti demon has begun to retreat step by step, and he is about to defeat it.

at the same time,

Teacher Miao, standing in front of the podium, stared at the students present, feeling a little helpless and depressed. The quality of this year's top students did not seem to be very high. With such a simple question, except for the national contestants, the rest were almost scratching their heads.

Forget it
Just think of it as selecting generals from a group of dwarfs. Just pick a few capable ones and they can deal with the situation. As for whether those colleges and universities want them or not, it all depends on their own wishes.

Teacher Miao sighed helplessly and was about to take out his mobile phone. Suddenly he found a student present. He was not a contestant in the national competition, and he did not look like a top student. However, he was doing the questions, and he was even faster than those contestants in the national competition!

what's the situation!
He. Who is he?

Why is the speed so crazy? What the hell. Is there something wrong with my eyes? Why am I seeing afterimages?
Teacher Miao rubbed his eyes, then looked straight again. Only then did he realize that it was not an illusion in his eyes, but the opponent's speed was so fast that it could not be captured by the naked eye, so the afterimage appeared.

Graffiti?

Is he graffiti?
It's impossible for anyone to think that fast! This must be graffiti!
As a training teacher for the International Mathematical Competition, he sentenced Chen Xiaoxin to death immediately. In his eyes, Chen Xiaoxin's behavior was tarnishing mathematics and the cornerstone of science and technology. Such a person did not deserve to be here.

While Teacher Miao was feeling indignant, Chen Xiaoxin was almost finishing his work. There were still about thirty seconds left before the estimated two minutes. At the same time, the two pretenders beside him also noticed his incredible speed. They were both stunned for a moment.

what's the situation?
I just didn't see him for a minute, and he...he wrote so much?
Although they didn't know whether Chen Xiaoxin's problem-solving process was correct, such an exaggerated speed made the two of them a little flustered. They took a deep breath, adjusted their emotions, and re-entered the state of solving the problem. However, it was obvious that they were slightly affected and did not have the calmness at the beginning.

at this time,

Chen Xiaoxin silently put down the pen in his hand and let out a long breath.

Complete
It feels so good to break through my own limits again!

The only drawback is that the question is too simple and not stimulating at all. It's really boring!

Chen Xiaoxin curled his lips, and glanced to the left and right with the corner of his eyes. Seeing the two top-grade pretenders still writing, the corners of his mouth couldn't help but raise a faint arc.

how?

No more pretense?

Today I will tell you two, this is not the way to pretend!

Anyway, you two should take care of yourselves and reflect on yourself. Don't act so pretentious in the future. In the academic world, harmony is the most important thing. You should focus on studying and not fighting among yourself.

"teacher!"

"I hand in the paper!"

Chen Xiaoxin slowly raised his hand and spoke to Teacher Miao in front of the podium.

In an instant,
Everyone present went crazy and turned to look at him, including the two show-offs beside him, as well as last year's first place winner Hu Wenjing and second place winner Zhang Kai. Everyone's face was filled with fear and disbelief, and they were even a little at a loss.

but
Only Yan Xiaoxi sat there and wrote down her solution process as if nothing had happened, because she was already used to it.

hum~
A group of people who have never seen the world.

At this time,

Teacher Miao walked over with a gloomy face, passing by several students. The answer area was almost blank. Even Hu Wenjing, who won the first place in the national mathematics competition last year, had only written half of it. He instantly became more convinced of his idea that the boy who handed in the paper was just scribbling.

He took away his paper without even looking at it, and asked Chen Xiaoxin to leave. Chen Xiaoxin, who was already very tired, did not notice the teacher's strangeness, and walked slowly towards the tea break area.
At this moment, Chen Xiaoxin has consumed a lot of energy and urgently needs to replenish water and food. Beef crisps, eat!
Durian pastry, eat!
Sausage pizza, eat!

The staff in charge of the tea break was about to burst when they saw Chen Xiaoxin eating so much. Didn't he just eat before? Oh, classmate, please save some! Leave some for others!
"Don't mind the little incident just now. Just continue to work on the questions seriously."

After Teacher Miao took away Chen Xiaoxin's paper, he did not look at the questions on it, but threw it aside. He looked around the room and said seriously: "Do it seriously, carefully, and well. This is related to whether you can stay here and whether you can be recommended for admission in advance."

Yan Xiaoxi frowned, looked at the teacher on the podium, and then glanced at someone's answer sheet. He felt a little unhappy, but didn't say much. Yan Xiaoxi naively thought that it was a unified grading, so he didn't worry about it anymore. He continued to work on his own questions, and only had a few steps left.

shhhhh--

There was a lot of noise in the activity center answering questions.

Go, go, go-

There was also a lot of eating sounds in the tea break area.

Those students were working hard on their homework, and Chen Xiaoxin was eating hard. I have to say, this place is simply like heaven!
“This, this.”

"Give me more. I love beef crisps."

"besides!"

"Cut some more watermelon, preferably chilled watermelon."

"fine."

"The diarrhea is on me!"

the other side,
Hu Wenjing and Yan Xiaoxi raised their hands at the same time. The first and third place winners in last year's national competition completed the proof of this problem at the same time.

Looking at the two super academic masters, Teacher Miao was very pleased. He then collected their answer sheets and compared the two answer sheets in his hand on the podium.

"Xiao Xi?"

"what happened to you?"

Hu Wenjing tugged at her sleeve and whispered, "Let's go quickly."

Yan Xiaoxi looked at Teacher Miao who was comparing answers with a gloomy face. At this moment, she finally realized that the man she liked was actually ignored. In an instant, a strong sense of dissatisfaction surged in her heart.

he.
You can only be bullied by me!
No one else was allowed to touch him.

Yan Xiaoxi was about to speak when Teacher Miao suddenly interrupted her and said to everyone present in a serious tone, "Students Hu Wenjing and Yan Xiaoxi both won the first place in this assessment."

The voice just fell,

Everyone exclaimed in surprise, and at the same time they were curious. What about the boy who handed in his paper first? What happened to him? Some people were curious. Naturally, some people were secretly happy. The two top-notch pretenders beside Chen Xiaoxin were secretly happy at this moment.

original
He doesn't have much ability.

"Teacher Miao!"

"Why don't you look at the first student who handed in his paper?" Yan Xiaoxi asked seriously.

Teacher Miao looked at Yan Xiaoxi and smiled slightly, "Xiaoxi, do you still need to look at this? You and Wenjing both took five minutes, but he only took less than two minutes. He must have been writing nonsense. You don't need to look at this. You and Wenjing should go outside for a while. You two probably haven't seen each other for a long time."

In fact, what he said made sense, because on the list handed over to Teacher Miao, Chen Xiaoxin's note was just "This person is very talented", so it was naturally ignored.

"teacher!"

"I strongly request you to take a look at his problem-solving process." Yan Xiaoxi said seriously, "I know his ability very well because he and I are in the same school. Although he has always been unknown, I dare to swear on my reputation that no one here can match him, including me."

Hu Wenjing was watching her secretly from the side, laughing in her heart, thinking that she was so eager to protect her husband!
After hearing what Yan Xiaoxi said, Teacher Miao was stunned. Looking at her serious expression, he secretly wondered in his heart, could it be that I was wrong?

But no matter how I think about it, it seems impossible!

Hu Wenjing and Yan Xiaoxi both took five minutes, but he took less than two minutes.
Although Teacher Miao was a conceited person to some extent, he was also very receptive to advice. He immediately took out Chen Xiaoxin's answer sheet and carefully looked at the proof process on it.

at the same time,

All the students put down their pens and stared at Teacher Miao on the podium.
