Chapter 108: Shooting problem

　　 For others, this must be a problem that takes time to calculate on draft paper.
　　 But for Cheng Nuo, is number arithmetic a problem?
　　 Cheng Nuo can only say that there are five words floating in the sky: This is nothing!
　　 First of all, this number is a multiple of 9 and a multiple of 7. Divide this number by 2, 4, and 8 and there will be 1 remaining. It is found that this number is an odd number, and then...
　　 The data in Cheng Nuo's mind is constantly calculating. Soon the correct answer will be filled in the blank.
　　 This question, which even a student master needs five or six minutes to complete, only takes ten seconds for Cheng Nuo.
　　 The third question. The score is worth three points.
　　 This is a question about the Digital Huarong Road.
　　 This digital Huarong Road is to place 15 numbers in a 44 square.
　　 A total of 16 positions, 15 numbers. In other words, there will be one position that is vacant.
　　 The placement of 15 numbers in the grid is completely random.
What Cheng Nuo and others need to do is to use the only space to move 15 numbers, and arrange the 15 irregularly arranged numbers in a sequence of 1, 2, 3, 4, 5... .
　　 This question mainly tests the reasoning ability of everyone.
　　 The title of this question in front of Cheng Nuo is like this.
　　381110
　　65131
　　24912
　　14713 empty
　　 The only thing everyone can use is the space in the lower right corner.
　　 At the first sight of the subject, Cheng Nuo constructed a digital Huarong Road model in his brain that was exactly the same as the computer screen.
　　 Then, Cheng Nuo is solving this kind of problem in the same way.
　　 First, change the first row to 1, 2, 3, 4.
　　 Then determine the positions of 5 and 8 in the second row.
At last……
　　 Ten seconds later, Cheng Nuo's closed eyes slowly opened. The data flow in the eyes flashed by.
　　 That's right, it's you, Pikachu!
　　 Cheng Nuo controlled the mouse and moved the numbers in Huarong Road step by step according to the steps he had already calculated in his mind.
　　 Cheng Nuo's hand speed is very fast, thanks to his eighteen years of single training.
　　 moves a total of 46 steps and takes 21.35 seconds.
　　 Although this is not necessarily the simplest movement plan, this speed is sufficient for Cheng Nuo.
Two questions after 　　, one is two points, each one is one point. It was easily resolved by Cheng Nuo.
　　 By this time, Cheng Nuo has completed five questions.
　　 The basis is divided into one-point one, two-point two-point, and three-point two-point.
　　 And time, only five minutes have passed.
　　 Most of the children's shoes who participated in the test still struggled on the first question.
　　…………
　　Madu, in an internet cafe. A young man sweating profusely while looking at the topic on the computer, he lowered his head to write and draw on the scratch paper. He kept whispering something in his mouth. Customers who eat chicken in Internet cafes are frequently eyeing.
　　Nowadays young people...have they all worked like this?
Between 　　, the sweaty teenager immersed himself in calculations for a long time, and suddenly took control of his face with excitement. He slapped his thigh and screamed, scaring many people.
　　 "That's right! Just use the Newton-Leibniz formula, Fermat's lemma, and the combination of the three theorems of Lagrange! Finally use the pinch to force the theorem, and it's OK!"
　　 Chicken eating crowd: "???"
　　Who can stand up and tell me what this person is talking about? !
　　 Before everyone could think too much, I heard a sound of slamming the table.
"Wow! This topology test is really tricky!" It was a student who seemed to be an adult from another position, who was wailing and rubbing his messy hair, "How can the area of ​​this Lelo triangle be solved? Ah ah ah!!!"
　　 Chicken eating crowd: "???"
　　 The chicken-eating crowd glanced at each other silently.
　　 Did we... come to the wrong place...
　　 They looked at the computer screen in front of them, filled with a deep sense of guilt.
　　 No, the guilt is too heavy, I want to eat the chicken to slow down.
　　………………
　　 On the other side, Kyoto.
　　 Wudaokou Institute of Technology (Tsinghua University) school forum. Also known as the top academic seminar group.
　　 Elementary school scum of the research group: "Hey, where did you guys go, why didn't you see them? I have another question about the Weierstrass function to ask him."
The discussion group said: "You don’t know yet. They are all doing a set of test questions. They should be very busy. They don’t have time to take care of you, the elementary school scumbag. I have a Mobius question here. No one is worried about it!"
　　 Research Group Xuehua: "I heard about it. The seniors seem to have received the invitation letter from "The Strongest Brain". It seems that it is time for the first round of testing."
　　Seminar Group 20: "Wow, the seniors are cheating. When will I become a man who is a bully?"
　　Winter of the research group: "I heard that "The Strongest Brain" has given out a total of 100,000 preliminary exams, but only one hundred people can participate in the recording. I don't know how many people in our school can become the last one hundred people."
　　 Study Group Xueba: "Anything is good, as long as it is not less than the Yuanmingyuan Vocational and Technical College next door!"
　　Discussion group grass: "Reconsideration!"
　　 Primary school of the seminar group: "+1"
　　Good person in the seminar group: "+1"
　　…………
　　 A large piece of reconsideration below.
　　………………
　　 The camera is back to our student Cheng Nuo~EbookFREE.me~ Twenty minutes after the start of the exam, Cheng Nuo has reached the tenth question.
"The three boys fell in love with a girl at the same time. In order to decide which of them could marry this girl, they decided to have a duel with a pistol. Xiao Li's hit rate is 30%, and Xiao Huang is better than him, with a 50% hit rate. The excellent shooter is Kobayashi, he never makes mistakes, and his hit rate is 100%. Because of this obvious fact, for the sake of fairness, they decided to follow this order: Xiaoli shot first, Xiaohuang second, Xiaolin last. Then the cycle, Until they only have one person left. Then who of these three has the best chance of surviving?"
　　 There are three options below, A, Xiao Li B, Xiao Huang C, Xiao Lin
　　 The basic score for this question is five points.
　　 is also the only question that Cheng Nuo has done so far with five points.
　　 Obviously, this question tests the players' reasoning ability, calculation ability, logical thinking ability, and...luck.
There are only three options for 　　. For some players, just blindly choose one, which is 33.33% correct. If you count it carefully for a long time, it is also 33.33% correct.
　　 Cheng Nuo frowned and read the title.
　　 The complexity of this question is really troublesome. It requires good logical reasoning and computing skills to not mess up the brain.
　　 Who was the first shot Xiao Li shot, and missed it?
　　 Did Xiao Huang die when it was Xiao Huang's turn, and who would he shoot if he didn't die? Missed? What will happen in the case of middle, and what will happen in the case of not?
　　 When it's the last Kobayashi's turn to shoot, what is the chance that Kobayashi will be alive? Who does he want to hit? Missed?
　　 Thinking about it this way, my scalp is tingling! !
