Tokyo: Simulation starts from the big sister next door

After all, nothing is harder than math.

While the two were talking, Qingshan High School had already added 20 points and temporarily ranked first.

Then, the host continued to read out the questions and the competition gradually became more intense.

During the competition, Kuroda Shin was very active. Sometimes he frowned and thought about the correct answer to the question, and sometimes he quickly pressed the buzzer to get a chance to answer the question.

At the same time, An Zeliang and Xing Gonglin, who were sitting next to them, were... in a daze...

Because of what happened last night, there was some awkwardness between them, otherwise they would have interacted with each other at this time.

Moreover, for An Zeliang now, those questions are just childish tricks. Since Kuroda Xin is so active, give him a chance to show his ability, and you can just relax and wait for the final big question.

And Xinggong Lin was also in deep thought.

But she was thinking about something else.

The warmth and pleasant smell of An Zeliang, who was sitting next to her, kept coming to her, which suddenly reminded her of the day when she returned to her room and seemed to smell a similar smell on her...

Was it really me who was harmed at that time, or was it that I was just infected with his scent because we were in the same bed?

But who took off my clothes?

At this time, she had no energy to think about the questions. Instead, she was thinking about what happened last night and worrying about whether she would be pregnant. She didn't even notice that as time passed, there was only the last super question left in the competition.

At this time, the host took the microphone and said excitedly:

"Dear audience, dear participating teams, the regular questions have been completed. Now only the super questions are left!"

As he spoke, the atmosphere on the scene suddenly became tense. After all, even the rules of the super big question were still unknown.

Before this, Kuroda Shin had always performed brilliantly, scoring 390 points, and Aoyama High School ranked third.

However, the most eye-catching person in the competition was not him, but the genius girl Tsukishima Saori. She was the only one in her team answering questions, but her score had reached 500 points, firmly ranking first.

At the same time, the three players from Dongda High School performed well and ranked second with 440 points.

The host looked at the score on the field and said:

"The highest score among the eight participating teams is 500 points, and the lowest score is 260 points. It seems that there is a big gap. But it doesn't matter, because we still have a super big question!"

"Everyone, please look at the big screen!"

As he spoke, the topic of the super big question appeared on the screen.

Given an integer N>1. There are N squared cable car stations at different heights on a mountain. There are two cable car companies A and B, each operating k cable cars, each running from one station to a higher station (without stopping at other stations in between).

The k starting points and k end points of the k cable cars of Company A are different from each other, and the cable car with a higher starting point also has a higher end point. The cable cars of Company B also meet the same conditions.

Two stations are said to be connected by a company if the higher station can be reached from the lower station by one or more cable cars of that company (without other movement between the stations being allowed).

Find the smallest positive integer k such that there are two stations connected by both companies at the same time. 】

As soon as this question came out, there was an uproar in the audience.

Many of the audience members were math teachers from various universities who came to observe the competition. They immediately discovered that the difficulty of this question far exceeded that of the previous questions!

This question is too difficult for high school students.

As an English teacher, Hoshiko Hayano looked at the reactions of the people around her with a look of confusion on her face.

"Teacher Ichigaya, is this question difficult? I can see that everyone's faces are not very happy."

Mr. Ichigaya frowned and replied, "This problem is very difficult even in the International Mathematical Olympiad. If I can't use pen and paper to calculate, I'm not sure I can figure it out quickly."

At this time, the host said slowly: "Everyone has seen the question, now I will announce the rules of this question."

"The last question is also a quick-answer question, and you can't use pen and paper to calculate. But this question is worth 200 points! If you answer it correctly, your team will get 200 points. If you answer it incorrectly, you will also lose 200 points! If no team answers within 15 minutes, the question will be invalid, and the team competition will end here!"

He didn't care that revealing the question first might give the contestants more time to solve it, or the organizing committee didn't care, because the organizing committee had done a thorough study before setting the question, and concluded that no one could give the correct answer within the scope of the rules.

Of course, it would be better if someone could do it.

This is the only way to demonstrate strength!

The eighth place is 240 points behind the first place, but only 180 points behind the second place. In other words, this question could turn the eighth place into the second place! If a team from another place answers the question correctly, they will instantly become the first place!

The genius boy from Dongda High School immediately stood up and said, "Teacher, this question is unfair! Such a high score will directly change the result of the competition, so what is the point of our previous efforts?"

The host motioned for the other party to sit down, then said with a smile: "Student, this is exactly what the organizing committee intended. Teams like yours can give up the opportunity to answer this question. In this way, even if other teams answer correctly, your worst place will be third. At the same time, for the lagging teams, this is an opportunity to strive for a higher ranking."

"At the same time, I would like to remind you again that the scores of the team competition and the individual competition should be calculated in proportion to the individual total score. If the score in the team competition is too low, no matter how high the score in the individual competition is, the final result may not be ideal."

"Will you choose to give it a try and strive for a better ranking, or play it safe and maintain the existing results?"

"Students, please think carefully! Start the countdown!"

Following the host's words, the contestants who were discussing a moment ago fell silent. He was right, the right to choose was in their own hands.

Hayano Hoshiko in the audience said indignantly: "What the hell, 200 points, is this a joke? We finally got third place, and if any of the next five teams get the answer right, then we will only be ranked fourth!"

Mr. Ichigaya, who was sitting next to him, said, "High risk and high return, or low risk and low return. This is forcing students to make a choice. After all, game theory is also a part of mathematics. The person who set the questions this time is not simple. Although it is just one question, it was tested twice!"

As he spoke, Mr. Ichigaya took out the paper and pen he brought with him and said, "15 minutes is really tight. Even I am getting nervous. Let me try to see if I can get the correct answer!"

In addition to Mr. Ichigaya, many people around him took out paper and pen to calculate. After all, many of the people present were math teachers or math enthusiasts, and they didn't want to miss such a challenge.

However, the contestants on the stage were not so convenient. They were not allowed to use paper and pen and could only do mental arithmetic.

Under the huge pressure of score and time, both the stage and the audience became very quiet.

Tsukishima Saori closed her eyes slightly and drew quickly on the palm of her left hand with her right index finger, as if she was doing calculations.

Her teammates said unwillingly: "Is there really no other way? Even though we are already first place, what if the other teams..."

But when it comes to math problems, if you don’t know how to solve them, you really don’t know how to solve them. Even if you look at them many times, it’s impossible for you to suddenly get the hang of it.

All hopes are placed on Tsukishima-san!

On the other side, beads of sweat had already appeared on Kuroda Shin's forehead.

He was also calculating quickly, but he was becoming more and more desperate. After thinking for a few minutes, he couldn't even find a suitable solution.

My current ranking is third, with 390 points. If I answer correctly, it will become 590 points, but if I answer incorrectly, it will become 190 points...

This choice is really overwhelming...

Kuroda Shin looked at An Zeliang and Xing Gonglin who were completely out of shape and said:

"You two should also think of a solution. Why am I the only one working hard? Have you ever thought about winning honor for the school? Even if it's not for the school, you should also think about yourself! If you could have played a role just now and won the second place, then at the worst you could have kept the third place, and you wouldn't have to go through so much trouble now!"

"Anze, you were very good at taking exams before, how come you can't answer a single question now! Really! I wish you were killed by the scumbag killer, so that someone else wouldn't be so useless!"

The scumbag killer has become a well-known urban legend in Qingshan High School. Because of this legend, Kuroda Xin had nightmares many times before. Although he is not a scumbag, he is also afraid. Now he is too anxious, so he said without restraint that he hopes An Zeliang will be killed by the scumbag killer.

But the four words "scumbag killer" made An Zeliang turn his head slightly and look at Kuroda Xin.

During the competition just now, An Zeliang saw that Kuroda Xin was so active, so he was at ease and lazy, and kept observing the audience. He finally confirmed that the quality of girls in this parallel world is much higher than that in his previous life.

Looking at An Zeliang's expression, Kuroda said unhappily:

"I said, you are not still hungover, are you? Did you drink again yesterday?"

"The competition has already started for such a long time, and you two haven't answered a single question. I got all 300 points by myself. If that's the case, why did you come to participate in the competition?"

Immediately afterwards, waves of complaints came out of Kuroda Shin's mouth, and An Zeliang felt that what he said made sense.

Although I don't like this guy Kuroda Shin, what he said is not wrong.

Be fair to the person, not the issue.

So An Zeliang looked at the big screen, read the question again, confirmed that it was the same as what he calculated, and then took the buzzer and pressed it.

"Ding!" The sound of the buzzer rang out.

"What are you doing!" Kuroda Xin was very shocked. He wanted to answer the questions in such a hurry. Are you trying to kill me?

The host looked at An Zeliang and said in surprise: "A team actually answered the question first. Please invite Qingshan High School to answer the question!"

An Zeliang took the microphone and said calmly: "k is equal to N squared minus N plus 1."

"Oops, I did it wrong." After hearing An Zeliang's answer, Mr. Ichigaya said in annoyance: "It should be N squared plus N minus 1."

Hayano Hoshiko's heart immediately rose to her throat: "Ah, in that case, wouldn't our team be reduced to 190 points?"

Mr. Ichigaya waved his hands hastily and said, "Not necessarily. I calculated it in a hurry. Maybe I am wrong."

Although he said this, he was actually just trying to comfort Hayano Hoshiko. After all, he had been paying attention to his teammates during the game. An Zeliang simply looked at the screen for a while and then announced the result. How could that be correct?

Even mental arithmetic can't be that fast! Impossible!

Kuroda Shin on the stage looked at An Zeliang who had already given the answer, and suddenly felt a chill in his heart.

"It's over! It's over! This guy must be playing tricks! He made me lose on purpose!"

Kuroda Xin said indignantly: "Are you crazy! I finally got these 390 points, and now I am going to be the last because of you! Anze! You are such a..."

Before he could finish his words, the host's voice came to Kuroda's ears: "The answer is correct, congratulations to Aoyama High School, 200 extra points!"

"What a... what a... genius!"

Kuroda Shin originally wanted to say that An Ze Liang was a lunatic, but the host's voice suddenly confused him.

He stood up in disbelief and turned to look at the host: "Excuse me, are you kidding? How can such a random answer be correct?"

At this time, the answer to the question appeared on the big screen, and it was exactly the same as what An Zeliang said.

The host's eyes were filled with shock. "Student, your team has gained 200 points. Aren't you happy? You are now the first place in the team competition!"

"This student named An Ze is simply a genius! He was able to calculate such a problem in his head so quickly... No, he definitely didn't calculate it so quickly. Maybe he has done such problems frequently before, so he can solve them so skillfully."

The host was also incredulous.

Kuroda Shin was speechless. Why, why couldn't he find any idea to solve the problem after thinking so hard, while An Ze Liang gave the correct answer in just a moment?

Isn't he just here to fill in the numbers?

Isn't he here to hold me back?

Kuroda was completely puzzled and sat down again helplessly.

At the same time, the talented students sitting opposite also stopped calculating and looked over in surprise.

How could he be so fast?

It's only been a few minutes...

"This guy... is quite interesting. He's a tough rival."

Tsukishima Saori looked at An Zeliang with an eager expression.

During the competition just now, she was also paying attention to the players of other teams. In addition to herself and her teammates, she carefully observed the seven teams and twenty-one people.

What left the deepest impression on her was the dazed duo from Aoyama High School, An Ze Liang and Hoshimiya Rin. They were like two mascots on the stage and never participated in the competition.

I originally thought that they were not strong enough, but it seems that they are hiding their abilities.

interesting.

Hayano Hoshiko was watching the big screen. Aoyama High School ranked first with 590 points. She said happily, "Teacher Ichigaya, Anze's answer is correct!"

Teacher Ichigaya also nodded excitedly: "Yes, I miscalculated. This boy, I thought he was not in good shape in this competition, but I didn't expect him to answer the super big question correctly! Such a boy with a good brain and good physical fitness, I really don't know what kind of girl can match him."

Hayano Hoshiko didn't know what she was thinking about and her face turned slightly red.

Is she worthy of him? There are already people here who have slept with him...

The team competition came to an end in such a dramatic way. After a short lunch and rest time, the individual competition was about to begin.

Twenty-four contestants from eight teams sat in the same examination room. The test papers had been placed on the table in advance, covered with pure white draft paper so that the contestants could not see the questions.

"Ring ring ring!"

As the bell rang, the individual competition officially began. Everyone picked up their pens and began to calculate quickly.

The chief invigilator stood on the podium, and four patrol teachers were patrolling back and forth in the examination room.

One year of elite learning experience has brought An Zeliang's knowledge to a completely different level from other students.

The competition topic in front of him was similar to doing addition and subtraction before the awakening system.

The only problem that bothers him now is that although he knows the answer as soon as he sees the question, his hand speed is not fast enough... After all, not everyone has the opportunity to constantly train his right hand.

The pen in An Zeliang's hand rubbed against the paper, making a constant "rustling..." sound.

Kuroda Shin, who was sitting diagonally behind him, couldn't help but be stunned. He was still immersed in the shock brought to him by An Zeliang in the team competition in the morning.

He even forgot to continue writing his own paper and instead looked at An Zeliang's back: "Why, why is he so fast? How did he know the answer this morning? I was working on a very complex question during my lunch break and didn't get the correct answer. How could he figure it out with just one look?"
