The top-notch movie queen wears books, disguises herself as a man and is handsome all over the world

Qin Jingyu raised his eyebrows when he saw Tian Jika coming out within ten minutes. This guy's desire to win was already aroused.

Tian Ji also said generously: "It's only five points, I'll give it to you."

She said nothing, leaning against the wall and reading the book in her hand. When Tian Ji saw that the other party was ignoring her, he changed positions angrily.

Someone came out of the office in the corridor and saw Qin Jingyu, "Is that you?"

She raised her eyes and greeted lightly: "Teacher Xiao Gu."

This person was Gu Huaiyu, and he had an impression of Qin Jingyu, a handsome and cold young man.

"The paper is handed in so soon?" Gu Huaiyu looked at the time and saw that the exam would not end in about half an hour.

Qin Jingyu nodded.

Gu Huaiyu glanced at the page she was reading, "Euler's theorem?"

"Ah."

"It's different from the Euler's theorem you learned in high school." He looked at it carefully again and said, "It's Euler's sieve method."

After saying that, he was busy delivering information.

Qin Jingyu's heart skipped a beat, thinking about the method?

……

After getting along for so long, Chen Mei really understood Qin Jingyu. After the exam, she walked directly to Qin Jingyu and asked, "What are you and Tian Ji doing?"

She didn't believe it was a coincidence that the two of them handed in their papers early.

Qin Jingyu touched his nose and told him about the bet with Tian Ji.

Chen Mei: "..."

Provoking the other party and then setting up a trap, Qin Jingyu found out that she was right as she guessed and started betting again!

But does Tian Ji know that Qin Jingyu’s favorite thing to do in the competitive class test is to submit the paper in advance and then crush them in terms of scores?

Chen Mei clicked her tongue and looked at the fat man in the distance, "I feel like the fat man will lose miserably this time."

The next forty minutes were spent waiting for the results. Chen Weifeng heard about Qin Jingyu's handing in the paper early and strongly disagreed. He was about to persuade him sincerely that this was not an ordinary quiz but a math league, so be careful!

"Teacher Chen, I am measured." Qin Jingyu said calmly: "Unless you don't believe in my strength."

Chen Weifeng: "Uh..."

In fact, he still didn't believe it a little bit, but he didn't dare to say it.

The scores for the preliminary test were quickly displayed on the big screen. The preliminary test was relatively simple, so there were a lot of perfect scores, and Qin Jingyu was listed in the first row with the highest score.

First place, Qin Jingyu from Imperial City No. 120 Middle School, with a perfect score of .

Fan Zhengdong looked at it and said in surprise: "I'll go, Qin Jingyu, you are worthy of being the God of Qin. You handed in the paper forty minutes early and got full marks. You're a pervert!"

"Yes, this is my first time participating in a competition, and I won first place in the first test."

Chen Weifeng was shocked when he saw Qin Jingyu's results.

He took back his inner disbelief and said to Qin Jingyu with a smile: "Not bad, not bad. I knew you could do it."

Qin Jingyu twitched the corner of her mouth. The score was within her expectation and she was not very surprised.

Instead, he raised his eyes to look in the direction of Yizhong, and sure enough he saw Tian Ji's black face that was about to drip with ink.

She just found Tian Ji's score, 105. Ranked above average and passed the preliminary test. There was also a player in No. Middle School who got perfect scores in the first test, but it wasn't him.

Tian Ji noticed Qin Jingyu's gaze and turned to look over. She opened her mouth and made a "loser" mouth shape.

The general was defeated.

Tian Ji was shocked and angry. What was surprising was that Qin Jingyu could get full marks in the first test. He had underestimated him. I was angry because I was influenced by the opponent and lost points on the last question. As a result, I was now ranked so low and the limelight was stolen by another player in the same field.

Loser!

Tian Ji clenched his fist fiercely, Qin Jingyu dared to humiliate himself like this, he would never lose, and the exam later would not be affected by him.

Qin Jingyu's perfect score in the first test must be a fluke!

for sure!

……

Chen Mei, Fan Zhengdong, and several others have passed the preliminary examination. However, half of the student team brought by Chen Weifeng still failed in the preliminary examination. On the other hand, all of the students from No. 1 Middle School were promoted. I have to admit that the strength of No. 1 Middle School is far higher than that of No. 7 Middle School. above.

At ten o'clock sharp, the first test starts on time.

This time Tian Ji learned his lesson and stopped messing around with Qin Jingyu. Qin Jingyu was too busy thinking about teasing Tian Ji because of what Gu Huaiyu said.

The difficulty of the questions in the first test is more than one level higher than that in the first test. After passing the threshold of the first test, this is the real mathematics competition.

Qin Jingyu's still methodical problem-solving was due to her previous day and night training, and the types of questions were familiar to her.

The paper was still handed in forty minutes in advance, and this time even Tian Ji didn't bother to look at it. When the invigilator learned that the candidate had scored full marks in the first test, he was numb to the fact that Qin Jingyu had submitted the paper early again. It seemed that Imperial City No. 7 Middle School had found a treasure this time.

Tian Ji saw Qin Jingyu handing in the paper at the same time again. This time he was steady. After the last question last night, he checked the entire paper carefully. He didn't believe it. Qin Jingyu was so lucky this time. After all, The first test paper is more difficult than the first test.

At this time, Tian Ji still naively believed that Qin Jingyu's perfect score in the first test was all due to luck. Maybe he knew that he was wrong, but he just didn't want to believe that he would be crushed by a freshman from No. 7 Middle School who had just entered the competitive class for two months!

Tian Ji turned in the paper in the last ten minutes. Because he had checked the answers, he felt a lot more confident this time. Unfortunately, when he went out, Qin Jingyu was concentrating on writing formulas on the paper and did not even look at him.

This makes Tian Ji feel that it is not interesting at all. People may not take him seriously at all, which is frustrating!

Once the test is over, wait for the score.

Tian Ji looked at the big screen. He had perfect scores. His coach and classmates were congratulating him. The glory that originally belonged to him was back. Just when he saw that he had a perfect score, he was still complacent, thinking that he could finally beat Qin Jingyu in terms of score, and felt proud, but when he saw Qin Jingyu's score, the smile instantly froze on his face.

Qin Jingyu from the No. 120 Middle School of Imperial City, with a perfect score of .

This is impossible!

Who is Qin Jingyu? Isn't he just new to competition? Why is he so good?

A sense of crisis crept into Tian Ji's heart! !

Suddenly I realized that provoking Qin Jingyu and making a bet with him before was the worst decision I had ever made! !

Qin Jingyu, with a perfect score of 120, successfully advanced to the final additional test with first place, which made Chen Weifeng smile from ear to ear.

Fan Zhengdong stepped on the lowest line and entered the additional test, while Chen Mei ranked higher than in the first test. They were almost immune to this perfect score monster, especially when they handed in their papers in advance.

After reading the scores, Chen Weifeng took them back to the hotel for dinner. There were still two hours before the afternoon game, and they could still take a nap when they went back.

Qin Jingyu did not return to the hotel and stayed in the library of Zhonghai University. Chen Weifeng did not say anything and told her to pay attention to safety before leading the team back to the hotel.

She grabbed a few bites of food in the school cafeteria, then ran to the library and stayed there all afternoon. Gu Huaiyu reminded her before that maybe she didn't need to insist on using directional induction to prove it.

-

The final prize will be determined in the extra test competition in the afternoon. Students with good luck will be recommended to prestigious schools or selected to join the national team to represent the national team, so the extra test questions are the most difficult.

Before the exam started, Tian Ji originally wanted to find out the details of the other party from Qin Jingyu. After getting perfect marks twice in a row, he did not dare to think that the other party was just relying on luck.

But Qin Jingyu kept writing formulas that he couldn't understand on the manuscript paper. He didn't raise his head until the invigilator handed out the test papers, leaving Tian Ji with no chance to talk to her.

Qin Jingyu put away the manuscript paper and pressed her eyebrows. She was almost able to sort out her thoughts.

The test time for the additional test is 150 minutes, and the test questions are four answer questions. The first two questions are worth 50 points each, and the last two questions are 180 points each, for a total of points.

The test questions are more profound, covering plane geometry, algebra, number theory and combinatorial mathematics.

The first three questions were quite satisfactory. When she solved the last one, she raised her eyebrows. It was actually about prime factorization.

After reading the questions, I found them to be a bit difficult and even a little over the top.

Generally, several methods can be used to solve this kind of problem, such as multiplication method, short division factorization method, etc.

Suddenly, something flashed through her mind. Maybe she could try using the screening method for this kind of question?

It just so happened that she had been studying in the library all afternoon today, and Zhengchou had not yet practiced this method, so this question came in handy for her.

The prime number sieve method is an efficient method for solving prime numbers. The basic idea is to first find the smallest prime number, then remove all numbers that can be divided by the prime number, and then repeat this process until all prime numbers are found.

For this competition question, it is obviously overkill and even very troublesome.

But who knows if you don’t give it a try?

First decompose the given integer N, then find the smallest prime factor P of N, and then filter P.

Qin Jingyu's brain was running very fast, and the pen in his hand was writing a long list of formulas on the test paper before he came up with the final answer.

Suddenly, something flashed through her mind. This time she caught it quickly and finally found the opportunity to solve the problem!

She knows! !

Finally, she understood what had troubled her before and why the backward induction method could no longer be implemented after reaching that point.

The heart is beating rapidly!

She now urgently needs to find a quiet place to continue her verification reasoning!

He couldn't do anything anymore, so he stood up and handed in the paper, and then ran out of the classroom quickly without waiting for the invigilator to say anything.

The invigilator looked at the young man's hurried back and quickly disappeared into the corridor, with a look of surprise and confusion on his face.

Why are you running so fast? Are you in a hurry to go to the toilet?

Also confused were Tian Ji and Chen Mei, who were in the same examination room. What was Qin Jingyu going to do?
