Tokyo: The simulation begins with the big sister next door

Chapter 109 107: Math Contest!First in a row!

After the players from the eight teams were seated, the host who presided over the game picked up the microphone and began to introduce the rules.

"This mathematics competition is divided into team competitions and individual competitions. However, no matter whether it is a team or an individual, the results will be included in the personal total score according to a certain proportion."

"That is to say, even if you are teammates now, there will only be one winner in the end."

When the host said this, the audience started to discuss.

This kind of game mechanism is very cruel. Even teammates will eventually become opponents.

The host looked at the contestants and continued to introduce the competition system: "In order to test everyone's quick thinking, this year's team competition no longer uses written tests, but adopts a rush-answer mode, and the use of paper and pencil calculations is prohibited, and mental calculations are required."

"Each quick-answer question gives 20 points for correct answers, and 10 points for wrong answers. You can only press the quick-answer device after I finish talking about the start of the quick-answer question. If you answer in violation of the rules, you will lose this opportunity to answer the question."

"In addition, the organizing committee of this competition has prepared a "surprise" for the students. At the end of the competition is a super big question with high scores. If you want to get a high score, the big question is a must-answer question, so please do it in advance Be mentally prepared."

Speaking of this, the host deliberately paused, and said with a smile: "Because this is the first time this competition uses this mode, the specific rules will not be announced until the super big question appears!"

"These are the rules of the game. Please keep the audience quiet. Now the game begins!"

After announcing the rules, the host said unhurriedly:

"The following is the first question."

"Nobita has 100 dorayaki on hand, and he wants to take them home to Doraemon. Nobita can take 50 dorayaki each time, but he has to eat them every time he walks 100 meters. One to replenish his strength, and now he is 5000 meters away from home, may I ask, how many dorayakis can Nobita bring to Doraemon?"

Following his voice, the content of this topic also appeared on the big screen behind the host. The big screen was specially prepared by the competition organizing committee for the audience to watch the competition clearly and intuitively.The content of the question, whether the player's answer is correct, and the scores of each team will be displayed on it.

After finishing talking about the topic, the host paused for more than ten seconds, and then said loudly: "The rush to answer begins!"

"Ding!"

As soon as the host finished speaking, the bell for the answer rang.

"Congratulations to Qingshan High School, you have the opportunity to answer the question. What is your answer?"

At this time, Kuroda Shin's hand was still on the answering machine, and he looked at An Zeliang and Xinggong Rin, as if to show off his successful answering.

An Zeliang complained silently in his heart: "If you have a girlfriend and you can still move so fast, what do you usually do?"

Kuroda Koto withdrew his eyes and replied confidently: "The maximum number of dorayaki that Nobita can take home is 16!"

After hearing the answer, Hayano Hoshiko in the audience changed his face slightly and began to think.

"Is this answer wrong? Walk 100 meters to eat a dorayaki, and you can only take 50 at a time. It is equivalent to taking 50 dorayaki and eating them when you walk home. He should not take any of them back."

Mr. Ichigani next to him smiled and asked, "But he still has to go back to get dorayaki after returning home. Doesn't he have nothing to eat during the 5000 meters back?"

Hoshiko Hayano thought for a while and clapped her hands together.

"That's right, so Nobita still owes 50 dorayaki after this back and forth, what should I do, can't I borrow it from Doraemon?"

"Haha, Teacher Hayano teaches English, so it's normal to think so, but there is another way, that is to take 50 of them and walk 100 meters towards home, then go back and take the remaining 50 and walk 100 meters towards home." rice."

Hoshiko Hayano frowned and calculated in her mind.

"What's the difference? It's 100 meters closer to home, and I ate 3 dorayaki. The consumption is the same as I said."

Mr. Ichigaya replied: "It was the same at the beginning, but when we walked 1700 meters towards home, we consumed a total of 51 dorayaki and left 49. Nobita can take up to 50 dorayaki, so he You can walk the remaining 49 meters with those 3300 dorayaki in one go.”

Hearing this, Hoshiko Hayano's eyes lit up.

"In this way, he needs to eat 33 dorayaki for the rest of the journey, and there will be 16 left when he gets home!"

Mr. Ichigaya nodded: "That's right, so Kuroda-san's answer is correct."

"The world of mathematics is really interesting." Hoshiko Hayano said this, but she was thinking in her heart: Does Anze's good game skills have a lot to do with his good math scores?
After all, nothing is harder than math.

While the two were talking, Qingshan High School had already added 20 points, temporarily ranking No.1.

Immediately afterwards, the host continued to read out the title, and the competition gradually became more intense.

During the competition, Kuroda was very active, sometimes frowning, thinking about the correct answer to the question, and sometimes pressing the answering machine quickly to fight for the chance to answer the question.

At the same time, An Zeliang and Xinggong Rin, who were sitting next to each other, were... in a daze...

Because of last night, they were somewhat awkward, otherwise they would have interacted at this time.

Moreover, for the current An Zeliang, those topics are just children's tricks.Since Kuroda is so active, give him a chance to show off, let him fish with peace of mind, and wait until the final big question.

And Xinggong Rin was also thinking.

But, she was thinking about something else.

The temperature and pleasant smell from An Zeliang's body sitting next to her kept coming, reminding her suddenly that after returning to her room that day, she seemed to smell a similar smell on her body...

Could it be that he was really harmed at that time, or was it just because he was in the same bed that he smelled like him?
But who took my clothes off?
At this time, she has no energy to think about the topic at all, but has been thinking about what happened last night, and worrying about whether she will be pregnant. She didn't even realize that with the passage of time, there was only the last super big question left in the competition. up.

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

"Every audience, all participating teams, the regular questions are over, and now only the super big questions are left!"

Following his words, the atmosphere on the scene suddenly became tense. After all, even the rules of super big questions are still unknown.

Before that, Kuroda Shin had been performing brilliantly, scoring 390 points, and Aoyama High School therefore ranked third.

But the most eye-catching player in the competition was not him, but Saori Tsukishima, a girl named genius.In her team, she was the only one answering the questions, but her score had already reached 500 points, ranking No.1 firmly.

At the same time, the three players from the High School Affiliated to Dongda University performed well, ranking second with 440 points.

The host looked at the scores on the field and said:
"Now the highest score of 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 super big questions!"

"Look at the big screen everyone!"

Following his words, a super big question appeared on the screen.

[Given an integer N>1. There are N square cable car stations with different heights on a mountain. There are two cable car companies A and B, each operating k cable cars, each running from a station to a higher station (do not stop at other stations in the middle).

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

We say that two stations are connected by a certain company if it is possible to reach the higher station from the lower station by one or more cable cars of the company (no other movement between stations is allowed in between).

Find the smallest positive integer k, so that there must be two stations connected by two companies at the same time. 】

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

Many of the audience present were mathematics teachers of students from various universities who came to inspect this competition, and they immediately discovered that the difficulty of this question has far exceeded the previous ones!

For high school students, this question is too difficult.

Hoshiko Hayano, who is an English teacher, looked at the reactions of the people around her with only blankness on her face.

"Mr. Shigu, is this question difficult? I see that everyone's faces are not very good-looking."

Mr. Ichigaya frowned and replied: "This question, even in the International Mathematical Olympiad, is still very difficult. If I can't use pen and paper to calculate, I am not sure that I can calculate it quickly."

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

"The last question is also a quick-answer question, which cannot be calculated with pen and paper. However, the score of this question is 200 points! If the answer is correct, the team will add 200 points. If the answer is wrong, 200 points will be deducted! If it takes more than 15 minutes If no team answers, the question will be invalidated, and the team competition will end here!"

He doesn't care that showing the problem first may give the contestants more time to solve the problem, or the organizing committee doesn't care.Because the organizing committee has done careful research before setting the question, the conclusion is that no one can make the correct answer within the scope allowed by the rules.

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

This can reflect the strength!

No.8距离No.1有240分的差距，但是距离第二只有180分的差距。也就是说，这道题可能让No.8变成No.2！如果是其他名次的队伍答对了题目，将瞬间变成第一！

The gifted boy from the High School Attached to Dongda University immediately stood up: "Teacher, such a question is unfair! Such a high score will directly change the result of the competition, so what's the point of our previous efforts?"

The host motioned for the other party to sit down, and then said with a smile: "Classmates, this is exactly the intention of the organizing committee. You can give up the chance to answer this question at the High School Attached to Dongda University. In this way, even if other teams get the answer right, you guys are the worst!" It is also No.3. At the same time, for the lagging teams, this is an opportunity to hit a high ranking."

"At the same time, I would like to remind everyone again that the scores of both the team competition and the individual competition must be included in the total score of the individual in proportion. 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. "

"Do you choose to give it a go and hit a better ranking, or to win steadily and keep the existing results?"

"Students, please think carefully! The timer starts!"

Following the host's words, the contestants who were discussing just now fell silent.He is right, the choice is in his own hands.

Hayano Hoshiko in the audience said angrily: "What are you doing, 200 points, isn't this a joke? I finally got No.3. If any of the following five teams got the answer right, wouldn't we have to settle for fourth place? Already!"

Teacher Ichigaya sitting beside 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 questioner this time is not simple, although It's just one question, but two assessments have been conducted!"

While talking, Mr. Ichigaya took out the pen and paper that he carried with him: "15 minutes, the time is really tight, and even I am nervous. Let me try to see if I can get the correct result!"

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

But the contestants on the stage are not so convenient. They are forbidden to use paper and pen, and can only do mental calculations constantly.

Under the huge score and time pressure, both on stage and off stage became very quiet.

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

Her teammates said unwillingly: "Is there really no other way? Although we are already No.1, what if other teams..."

But if you don’t know how to do math problems, you really don’t know how to do it. Even if you read it many times, it’s impossible to suddenly get enlightened.

All hopes are pinned on Tsukishima-san!
On the other side, there were fine beads of sweat on the forehead of Kuroda Shinobi.

He was also calculating quickly, but he became more and more desperate. After a few minutes of thinking, he didn't even find a suitable solution to the problem.

The current ranking is No.3, 390 points, if the answer is correct, it will become 590 points, but if it is wrong, it will become 190 points...

Such a choice is really overwhelming...

Kuroda Shin looked at Yasawa Ryo and Hoshimiya Rin who were completely out of state and said:
"You two should also think of a way. Why am I the only one who is working hard? Have you ever thought about fighting for honor for the school? Even if it's not for the school, you should think about it for yourself! If you can play some role just now to win To No.2, the worst result can also keep the third place, now there is no need to be so troublesome!"

"Anze, weren't you very good at the exam before, why didn't you answer a single question now! Really! If only you were killed by the scumbag killer, it would be fine if you were replaced by someone else!"

The scumbag killer is already a well-known urban ghost story in Qingshan High School. Because of this legend, Kuroda Shin has had many nightmares before. Although he is not a scumbag, he is also afraid.Now he was too anxious, so he said that he hoped that An Zeliang would be killed by the scumbag killer.

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

During the game just now, An Zeliang saw that Kuroda was so active, so he was relieved to be lazy and kept observing the audience off the court.He finally confirmed that the quality of the girls in this parallel world is much higher than that in the previous life.

Looking at An Zeliang's expression, Kuroda said dissatisfiedly:
"I said, aren't you still hungover? Did you drink again yesterday?"

"It's been so long since the competition started, you two didn't answer a single question, and I got all [-] points by myself, so why are you here to participate in the competition?"

Immediately afterwards, waves of complaints spewed out from Kuroda Shin's mouth, and Yasawa felt that what he said made sense.

Although he didn't like Kuroda Shin, he was right in saying these words.

Treat people wrongly.

So An Zeliang looked at the big screen, read the question again, confirmed that it was the same as his own calculation, and then took the answering machine and pressed it.

"Ding!" The answering machine sounded.

"What are you doing!" Kuroda Koto was shocked at the side, answering the question in such a hurry, is this trying to kill me!

The host looked at An Zeliang and said in surprise: "There is actually a team rushing to answer the question. Please ask Qingshan University to answer the question!"

An Zeliang took the microphone and said calmly: "K is equal to the square of N minus N plus 1."

"Ah, I made a mistake." Hearing An Zeliang's answer, Mr. Ichigani said angrily, "It should be the square of N plus N minus 1."

Hayano Xingzixin on the side suddenly raised his throat: "Ah, in that case, wouldn't our team become 190 points?"

Mr. Shigu hurriedly waved his hand and said: "Not necessarily, not necessarily, I calculated in a hurry, maybe I was wrong."

Although he said so, it was actually just to comfort Hoshiko Hayano.After all, he has been paying attention to his players during the game. An Zeliang simply looked at the screen for a while and said the result. How could it be correct!
Even mental arithmetic is impossible so fast!impossible!

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

"It's over! It's over! This guy must be playing tricks! He deliberately let me lose!"

Kuroda Shin said with a look of resentment: "Are you crazy! I finally got these 390 points, and now I have to become the bottom one because of you! Anze! You are really..."

Before he finished speaking, Kuroda Shin heard the host's voice: "The answer is correct, congratulations to Qingshan High School, plus 200 points!"

"What a... is a... genius!"

Kuroda Shin wanted to say that An Zeliang was a lunatic, but the host's voice caught him off guard.

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

At this time, the answer to the question also 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, aren't you happy that your team has gained 200 points? Now you are No.1 in the team competition!"

"This student named An Ze is simply a genius! He can actually calculate such a problem in his head so quickly... No, it must not be calculated so quickly. Maybe he is so proficient because he often did such problems before. Answer it."

The host is also unbelievable.

Kuroda Shin couldn't even say a word, why, why did he think hard and couldn't find a way to disintegrate, but An Zeliang gave the correct answer in just a moment?

Didn't he come here to make a fool of himself?

Didn't he come to hold me back?

Kuroda couldn't understand it, and sat down weakly.

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

How could he be so fast?

It's only been a few minutes...

"This guy... is interesting, he is a strong enemy."

Saori Tsukishima looked at An Zeliang, showing an eager expression.

During the competition just now, she was also paying attention to the players of other teams. Besides her and her own teammates, she had carefully observed all 21 players in seven teams.

What left the deepest impression on her was the dazed duo of Aoyama High School, An Zeliang and Xinggong Rin, just like the two mascots on the stage, they never participated in the competition.

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

interesting.

Hoshiko Hayano in the audience looked at the big screen, and Aoyama High School ranked first with a score of 590. She said happily, "Mr. Shigu, student Anze's answer is correct!"

Mr. Shi Gu also nodded excitedly: "Yes, I made a mistake. I thought this kid was out of shape this time, but I didn't expect to answer the super big question correctly! Such a good brain and good physical fitness Good boy, I really don't know what kind of girl can match him."

Hoshiko Hayano didn't know what to think of, her face turned slightly red.

Is it worthy of him? Someone present has already fucked him...

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

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

"Ring bell bell!"

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

The chief invigilator was standing on the podium, and the four visiting teachers were patrolling the examination room.

The one-year study experience of the elite version has put An Zeliang's knowledge at a level completely different from other students.

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

The only problem that bothers him now is that although he already knows the answer when he looks at the question, his hand speed is not enough... After all, not everyone has the opportunity to constantly exercise their right hand.

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

Kuroda Shin, who was sitting obliquely behind him, couldn't help being stunned, and now he was still immersed in the shock brought by An Zeliang in the morning team competition.

He even forgot to continue writing his own paper, but looked at An Zeliang's back: "Why, why can he be so fast? How did he know the answer in the morning? I have been calculating the super big question during my lunch break, but I didn't get it." The correct result, why did he count it at a glance?"

At this time, a visiting teacher came to him, frowned and knocked on Kuroda Shin's desk: "Student, please concentrate on doing your own papers."

Kuroda Shin turned his eyes away from An Zeliang, but he still couldn't concentrate.

An Zeliang quickly finished the paper, then looked up at the wall clock on the wall, 10 minutes had passed since the start of the exam.

examine?nonexistent.

An Zeliang raised his hand: "Teacher, I have finished the answer, can I hand in the paper in advance?"

The invigilator was stunned for a moment, then nodded.

"can."

The search before the game was very strict, and all the signals were blocked in the exam, plus five teachers invigilate the exam, even if some students went out early, there was no chance to help others cheat, so the rules allow early departure.

An Zeliang packed all his things, put the paper on the podium, and left the examination room to find his teacher.

"In the past, there were contestants who scribbled a lot on the paper and handed it in half an hour because of their poor level. This time it is the same." The invigilator thought while picking up An Zeliang's test paper.

He is a professor in the Department of Mathematics of Dongda University, but he didn't know what the topic was until he saw An Zeliang's test paper.

Followed by.

As he reviewed An Zeliang's test paper, the invigilator's expression became more and more surprised. He leaned down and began to carefully observe the content on the paper.

It's not scribbling, but answering questions seriously?
The problem-solving ideas for each question are very efficient and simple, and the steps to solve the problems are clear and clear.And many solutions are only accessible to universities or even graduate students.

So what about the answers... Even the professor of mathematics couldn't determine whether the answers to these questions were right or wrong for a while.

Unable to restrain himself, he took out the pen and paper at hand and began to calculate.

correct!correct!Still correct!

The invigilator looked at the other contestants who were writing hard, and walked to the office of the competition organizing committee with An Zeliang's paper.

Soon, the invigilator returned to the examination room, and he said loudly: "Everyone, An Zeliang from Qingshan University has already got full marks, and he handed in the papers at the earliest time, and after the teacher's examination, all the papers are full marks, so it's confirmed." It's No.1 in the individual competition, and everyone after that has to work hard!"

Just now he handed over An Zeliang's paper to the competition organizing committee, and after reviewing it again, he finally confirmed that An Zeliang's paper was indeed full marks.

He discussed with the organizing committee and decided to announce An Zeliang's results.

After all, the players who can participate are all talented in mathematics, and the organizing committee also wants to see how these players will perform under the sudden pressure.

Hearing the invigilator's words, Kuroda Shin's hands trembled, and the sweat on his forehead began to come out continuously. The whole person seemed to be trapped in a nightmare named Yasawa, and the spirit that had been difficult to concentrate became even more flustered.

And Saori Tsukishima clenched the pen she was answering. Could it be that the super big question in the team competition was not fooled by the other party, but calculated?

Thinking of this, she couldn't help but look towards the door, thinking about that figure for a few more seconds in her mind.
