Chapter 49: It’s okay if you don’t say it, it’s even worse if you say

　　　　 Faced with the difficult exam questions, all the participating candidates looked solemn.
　　 Lu Li had the feeling of racking his brains when facing these problems. The difficulty was beyond imagination, and it seemed even more difficult than the "previous international Olympiad test questions" that Lu Li had once brushed.
　　 in the office building of Mizuki University.
　　 Many teachers and professors of the Olympic Mathematics Competition Organizing Committee were a little surprised when they saw this test paper.
　　 "This difficulty...a bit scary!"
　　 A staff member who graduated from mathematics graduate student, looked at the test paper, and sweat broke out on his forehead.
　　 If I did this test paper back then, I’m afraid... I failed the test, right?
　　 "What is the National Olympic Mathematical Olympiad? It is to select talents for the national team. Those who are selected are to participate in the International Mathematical Olympiad."
　　 An old professor admired this test paper very much, "I can't do this test paper. What international competitions are you participating in? Don't be ashamed."
　　 "Elder Wang, you are right!"
　　 Everyone nodded and echoed.
　　 It’s just that, in private, he secretly slandered: It’s right in principle, but... to select the members of the national team, we can choose it during the winter camp training!
　　 In this national competition, some questions can be lowered a little bit, and only the difficulty of individual exam questions can be increased. Don't let everyone die too ugly!
　　As soon as your test paper comes out, I am afraid that many people will cry in this national competition. The entire army of the participating teams was wiped out, and many candidates returned with zero eggs. Why is this so human?
　　 In the examination room.
　　 As time passed slowly, the candidates were already shaking.
　　 Some of the faces turned blue, some had straight eyes, some were heartbroken, and some were crying silently.
　　 can come to this point, can come to the examination room of the national competition, who is not a student? Who is not the proud son of heaven?
　　 However... in front of this test paper, the scenery of the past, the glory of the past, the pride of the past, like soap bubbles, instantly disappeared and broke completely clean.
　　 tore open the gorgeous coat, leaving only the wound.
　　 I always thought I had a high IQ, but now I found that...I am just a mentally retarded person in front of this test paper!
　　 Lu Li also felt that he was a "fake schoolmaster".
　　 After finishing the three questions with ideas to solve the problem, the fourth question took a full half an hour before stumbled.
　　The fifth question... Fuck! What the is this? It seems to be a geometric problem, but in fact it is an algebraic problem again. Using algebra to solve it will return to geometry.
　　 can't do it, my mind is going to be messed up!
　　 Lu Li let out a long sigh, and left the fifth question aside, and did the sixth question first.
　　This question...
"There are 17 people in a QQ group, and each of them chats with others privately. They discuss three different topics in total. Every two people only discuss one topic. Please verify: there are at least three of these people who are The topics discussed are the same."
　　Shen Te Mo QQ Group! I use WeChat!
　　 Discuss topics in the group, why do you want to chat privately? Don't you know how to send the group directly? Even if it is a driving topic, there is no need to chat privately, but to discuss in groups!
　　 Ma Maipi! I hate driving and chatting privately!
　　 Lu Li cursed a few words secretly, the inspiration broke out in his mind, and he quickly found a way to understand the problem.
　　 Sure enough, driving is good for physical and mental health!
　　 I started flying, and the sixth question was solved quickly. Then... Lu Li looked at the fifth question again.
　　 "Four real numbers. The product of any three of them plus the fourth number is equal to 2. Find all possible values ​​of these four numbers."
　　2……2……Love……is made!
　　 I have to love when I die, not to be incisive and unhappy!
　　 I don't know if it was the inspiration for driving and flying, Lu Li suddenly had a flash of inspiration and thought of understanding the problem.
　　 There are some questions, and there is a layer of yarn between them. I can vaguely see the direction, but they always linger outside the door, unable to enter.
　　 Only by tearing off this layer of camouflage and finding the right direction, can he drive straight in, hit Huanglong, and kill seven in and out.
　　 The surging passion is like a raging tide, and I tossed back and forth several times, until the momentum is like a broken bamboo, and it is a thousand miles!
　　 Get it done!
　　 There are so many beautiful national games, which has attracted countless heroes.
　　 Some people smashed their halberds into sand, some were bloodied, some were still struggling.
　　 And I... just feel dull!
　　 Lu Li threw away the water-based pen in his hand, and there was a emptiness in his heart, like sage time.
　　……
　　The exam is over!
　　 Lu Li also felt exhausted physically and mentally, and felt weak. So don’t drive if your kidney is not good...Oh no, don’t learn Mathematical Olympiad.
　　 took a deep breath, and Lu Li cheered up and walked out of the examination room.
　　 By the green belt outside the examination room, Lu Li joined Liu Qin.
　　 At this moment, Liu Qin has a depressed face and looks very unhappy.
"what happened?"
　　 Lu Li walked up and asked concerned.
　　 "I have a question... I didn't finish it!"
Liu Qin looked at Lu Li with a bitter face, his eyes flushed, "It took too long to think about the idea of ​​solving the problem. When I came up with the idea of ​​solving the problem, there was not enough time. I didn't finish all the steps before I wrote the answer. It's written."
　　 "That's it!"
　　 Lu Li smiled, "It's okay! You just omitted a few steps. The problem has been solved, and a little point deducted at most. Besides, what if it is not done? Look at other people..."
　　 Looking in the direction indicated by Luli, Liu Qin saw...the candidates who walked out of the examination room were full of sorrow and grief.
　　 "You mean...I'm already doing well in the exam?"
　　 Liu Qin breathed a sigh of relief~EbookFREE.me~ I have made an appointment with you to participate in the international competition, I...I always worry about being eliminated. "
　　 "Don't worry! No way."
　　 Lu Li comforted, and pointed to the exit of the examination room again,
Look, Zhang Yu and the others have also come out. You can ask them later. I can guarantee that you are definitely doing well in the exam.

　　 said, Lu Li waved to the other teammates in Chuan Province, "This way! This way!"
　　 Zhang Yu, Yang Wenli and Wang Yujia hurried up when they saw Lu Li beckoning.
　　 "You...how did you do in the exam?"
　　 Liu Qin was very concerned about the results and quickly asked the other three.
　　 "Don't mention it!"
　　 Yang Wenli let out a long sigh, his face was miserable, wrinkles appeared on his fat face, "This question...too difficult! Get a hammer! I just made three questions."
　　 "I just did two questions! Ma Maipi! Which tortoise son asked the question? His ancestors got it! Get a shovel!"
　　Wang Yujia is so angry that he doesn't have foreign words, his mouth is full of the smell of Xichuan soil stubble.
　　 "I died too."
　　 Zhang Yu couldn't hold back the image of Brother Ku. The original facial paralysis was already full of misery. "I also only did three problems. Others... I can't think of any ideas for solving problems."
　　 After finishing speaking, Zhang Yu raised his eyes to Lu Li and Liu Qin, and asked, "What about you? How did you do in the exam?"
　　 "Oh! Stop talking about this."
　　 Lu Li let out a long sigh, "It's okay not to say it, it's even more unhappy to say it to you."
　　 "Okay! Not to mention it!"
　　 When Zhang Yu heard this, they felt that Lu Li must have died.
　　Don't mention it! Not to mention it!
　　The national competition is over, go home and prepare for the college entrance examination! The top pick in the college entrance examination...you can still compete.
