Chapter 124: The most difficult in history
Chapter 124 The most difficult in history
“Yunsu, come here!”
Chen Zhirun’s roar can be heard on this floor of the dormitory building where the Chinese national team lives.
“What’s wrong? Coach.”
Li Yanshuang and others who had just returned from the exam asked in confusion, this was the first time they saw Coach Chen so angry with Su Su. What did Sister Yun do?
“Old Chen, why are you so angry?” Professor Wang was holding his own thermos cup, still cheerful. He was in charge of the rear today and did not accompany the exam. He didn’t know what happened.
“Let her speak for herself!” Chen Zhirun looked at Yunsu and became angry.
Yunsu was at a loss, and she couldn't figure it out, "I didn't do anything."
"You didn't do anything? What would you have done if you had done something?" Chen Zhirun was so angry that he puffed his beard and stared at her words. "There are forty-two teams participating, 210 students, so many coaches, and even The chairman of the examination committee was staring at you, you were the only one, and you handed in your papers only forty minutes after the exam started, and walked away gracefully. "
Professor Wang’s hand shook and he almost dropped the thermos cup to the ground. He was stunned.
"Chairman Smith thought something had happened, and even sent someone to ask the invigilator. Let me ask you, are you unable to sit still for a while? Can't you check it carefully to see if there is any negligence?" Chen Zhirun As he spoke, he began to cover his heart again. He must apply for a work-related injury this time when he goes back!
“Pfft!” Chen Zhirun spat out a mouthful of water, “What did you say? Did you bet on the right question?”
“Okay, okay.” Yunsu was speechless.
Chen Zhirun finally looked better. He opened the cup and asked Li Yan and the others, "By the way, what did you want to say just now?"
“If you’re showing off, you have to look at me, Sister Yun.” Chu Hai gave a thumbs up in admiration.
Chu Hai scratched his head, "It's not exactly the same, but the general solution is almost the same. We just need to make some transformations. If Sister Yun hadn't told us yesterday, we might not have been able to figure out how to solve it for a while."
He couldn't care less, "How is this possible? Aren't the questions on the test paper all original questions? How is it possible that the bets are correct?"
To a certain extent, she is already the question maker!
Chen Zhirun, who just finished scolding Yunsu, now wants to offer it to her. This is really a big treasure that makes people "surprised" and "joyed" all the time.
They all looked at each other, and Feng Qinwei stood up, "We just want to say that Sister Yun got it right on the second question of the test paper."
Feng Qinwei is from H Province, and the face-changing performance is their intangible cultural heritage.
Just after the exam, Li Yan and others wanted to say something to him, but he was so angry that he had no intention of listening.
Professor Wang finally lost his grip on the cup and dropped it.
“Four and a half hours.” Yunsu whispered.
My dear, you dare to hand in your paper in advance in this kind of competition, you are so awesome!
Li Yanshuang covered her mouth and was happy.
“Is your face-changing performance as fast as Coach Chen?” Chu Hai whispered to Feng Qinwei quietly.
Oh, it’s not exactly the same, it’s pretty much the same.
Chen Zhirun gritted his teeth, "What's wrong with four and a half hours? Even if it's ten and a half hours, just sit there!"
"Su Su, you must be tired from today's exam, right? We won't disturb your rest." Chen Zhirun turned around and put on a loving smile.
God knows how excited they were when they saw the title.
Almost like a ghost! Chen Zhirun is about to throw the cup. What does it mean that he can get roughly similar questions? It shows that the person who asked the question has completely guessed the intention and thoughts of the person who asked the question. This is not just a matter of looking at the past questions. This requires extremely terrifying logical reasoning and analysis skills.
Feng Qinwei glanced at Coach Chen and said firmly: "No!"
Li Yanshuang couldn't help laughing anymore.
On the first day of the exam, everyone was in good condition and felt half relieved.
May 2, the second day of the IMO exam begins!
The moment they got the test paper, many students changed their minds. The difficulty was not at the same level as the first day.
Smith smiled warmly, "IMO, the purpose is to select the best and most mathematically gifted talents, and we still need to give some difficult questions."
The coaches present all smiled in agreement, but in their hearts, MMP asked such a difficult question that it would be fun to annihilate the whole army.
After yesterday's handover incident, many coaches were paying attention to Yunsu either explicitly or covertly.
Today's exam location changed. Yunsu arrived at the second exam room. As soon as the test papers were handed out, she heard a slight gasp, which made her a little more interested.
His eyes wandered to the last question, and Yunsu raised a smile at the corner of his mouth.
"A hunter and an invisible rabbit play a game on the European plane. It is known that the rabbit's starting position A0 coincides with the hunter's starting position B0. After n-1 rounds of the game, the rabbit is located at point An-1. The hunter is located at point Bn-1. In the nth round, the following three things happen in sequence..."
A magical invisible rabbit? Interesting.
This question can be said to be the most difficult question Yunsu has ever encountered so far, but for her, it is nothing, so she simply does this question first.
The gel pen scratched across the paper, leaving a rustling sound, and Yunsu wrote two pages of answer sheets on the answer to this question.
Rubbing his sore wrists, Yunsu continued to solve the first two questions. At this time, the wall clock in the examination room had just pointed to ten o'clock.
Chen Zhirun stared at the screen in the second examination room. After seeing Yunsu put down the pen, he showed a relaxed smile, and then immediately became nervous again.
Yunsu, who was heavily criticized yesterday, honestly did not hand in the paper in advance this time and waited until the end of the exam.
Chen Zhirun gritted his teeth and ignored the gloating expressions of other coaches. That's all. It would be nice if she could stay calm.
At 1:30 in the afternoon, the exam ended. Many candidates still failed to answer the third question after counting many pages. As soon as the test papers were collected, they lay on the table and burst into tears.
“Su Su, woo hoo, today’s questions are too difficult!” As soon as Yunsu left the examination room, Li Yanshuang wiped away tears. Yunsu patted her shoulder comfortingly, "It's okay, it's indeed a bit difficult."
Yunsu also said it was difficult? Li Yanshuang sobbed and asked, "Have you done it?"
After two seconds of silence, "...it's done."
Li Yanshuang cried louder.
Soon after, Li Yan, Chu Hai, and Feng Qinwei also came out, their faces a little ugly.
Li Yan and Feng Qinwei did it for the last question, but they had no confidence at all. Chu Hai only wrote a few words far-fetchedly.
“Sister Yun, how should we solve the last question?” Chu Hai wailed.
They just heard the invigilator talking, saying that the last question this time was the most difficult question in the history of IMO. How could they be so unlucky to encounter it?
"Two core concepts." Yunsu raised two fingers, "One, the cycle node N, and two, the maximum direction deviation angle. As long as you understand these two concepts, it is not difficult to solve this problem."
Several of them were all of the easy-to-understand type. After hearing Yunsu's words, they showed stunned expressions and began to think carefully.
“Bah bang bang.” Applause sounded, “You are indeed the strongest opponent in my opinion.”
Yunsu followed the sound and saw that it was the beautiful boy from the national team D.
Simon's blue eyes were full of admiration. He thought about the question for half an hour before cautiously answering it. Unexpectedly, Yunsu pointed out the key point right to the point.
What is the strongest? What opponent? Has this kid watched too many chuuni anime?
"The exam is over. We'll wait and see the results." Simon admitted that she was very strong, but he didn't think he would lose to her. He was looking forward to the final result.
“Huh? What?.” What on earth is he talking about?
Before Simon left, the members of the M national team came over again.
“Cute little oriental girl, don’t cry, it’s normal to fail in the exam.” Bernie said in a strange tone.
He thought for them self-righteously and said: "If you are willing to apologize to me now, I can pretend that I didn't have that bet."
“No, let’s continue the bet.” Yunsu said calmly.
“What bet?”
Simon asked Leon next to him, and Leon told him in a low voice about the bet between Team M and Yunsu.
Simon looked at Bernie up and down with a strange look in his eyes. Where did he get the courage to make this bet with Soda? are you crazy?
It is true that the ignorant are fearless.
“What are you looking at?” Bernie bulged his eyes.
Simon shook his head, "It's ridiculous."
Yunsu said with a headache: "Let's go." These people seemed to be suffering from a serious illness.
Chen Zhirun had already returned to the dormitory to wait for them. Seeing that a few people had wrong expressions, he didn't care about Yunsu sleeping in the examination room. He hurriedly comforted him: "We'll leave after the exam. Don't think about it."
He and Professor Wang had just seen the test paper. The last question was so difficult that he didn’t even dare to say that he could solve it in these few hours.
Professor Wang: “If you haven’t done it, others may not be able to do it either.” Although this shouldn’t be said, it is indeed the truth.
“Who says we haven’t done it yet?” Chu Hai retorted.
Chen Zhirun's eyes lit up, has this been done?
Feng Qinwei: “I did it, but I don’t know if it’s right or not.”
…”
It's okay, at least there is still a chance. Chen Zhirun comforted himself and looked at his top seed expectantly. Professor Wang was also full of expectations.
Yunsu nodded as expected.
“There’s a chance!” Chen Zhirun pumped his fist excitedly, and as long as Yunsu nodded his head, he was basically half stable.
Professor Wang: “Thank you everyone for your hard work. Let’s go out for a nice meal tonight!”
“Okay! Would you like me?” Chu Hai immediately forgot about his unhappiness.
Professor Wang rolled his eyes gracefully, "Competition funds!"
A group of seven people marched toward the...Chinese restaurant outside the University of London.
Chu Hai protested: “Why do we still have to eat Chinese food after we have gone abroad?”
“Are you sure you want to eat the food here?” Li Yanshuang asked hesitantly.
Chu Hai recalled the dishes in the canteen of the University of London and fell silent. Yesterday at noon, they saw a dish called Looking Up at the Stars. The name was very beautiful, so they ordered it. The dish that was served was a simple version of pizza. Three sardines were inserted and stared at them.
Several people’s pupils were shaken on the spot.
“Then let’s have Chinese food.” Chu Hai compromised.
In country R, Chinese food is considered high-end cuisine and is not cheap. Especially a few young people who are growing up eat a lot. Fortunately, the funds provided by the authorities are quite sufficient, and they ate happily. A meal.
All the heavy uneasiness of the past few months disappeared with this meal, and all that was left was waiting.
