Omnipotent Data

For others, it must be a problem that requires time to work on scratch paper.

But for Cheng Nuo, is number crunching a problem?

Cheng Nuo could only say that five words floated from the sky: This is nothing serious!

First of all, this number is a multiple of 9, a multiple of 7, and the remainder is 1 after dividing this number by 2, 4, and 8. It is concluded that this number is an odd number, and then...

The data in Cheng Nuo's mind was constantly calculating. Quickly fill in the blanks with the correct answer.

Cheng Nuo only needed ten seconds to solve this problem, which would take five or six minutes even for a top student.

third question. Points are worth three points.

This is a question about digital Huarong Road.

This digital Huarong Road is to place 15 numbers in a 4*4 grid.

A total of 16 positions, 15 numbers. That is, there will be one slot that will be vacant.

The placement of the 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 these 15 irregular numbers in order of 1, 2, 3, 4, 5... .

This question mainly tests everyone's reasoning ability.

Cheng Nuo's question looked like this.

3 8 11 10

6 5 13 1

2 4 9 12

14 7 13 empty

The only thing everyone can use is the space in the lower right corner.

At the first glance of the title, Cheng Nuo built a digital model of Huarong Road in his mind that was exactly the same as that on the computer screen.

Then, Cheng Nuo was solving this kind of problem in the same way.

First, you need to change the first line to 1, 2, 3, 4.

Then determine the positions of the second row 5 and 8.

at last……

Ten seconds later, Cheng Nuo slowly opened his closed eyes. The stream of data in his 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 calculated in his mind.

Cheng Nuo's hand speed is very fast, which is due to his eighteen years of training alone.

A total of 46 steps were moved, which took 21.35 seconds.

Although this is not necessarily the easiest moving solution, this speed is enough for Cheng Nuo.

For the next two questions, two points for one question and one point for one question. Cheng Nuo easily solved it.

By now, Cheng Nuo had completed five questions.

The basis is divided into one point for one point, two points for two points, and two points for three points.

As for the time, only five minutes had passed.

Most of the children's shoes who participated in the test were still struggling on the first question.

…………

Magic City, inside an internet cafe. A teenager was sweating profusely while looking at the topic on the computer, while lowering his head to write and draw on the draft paper. He was still muttering something in a low voice. It attracted the attention of those customers who eat chicken in the Internet cafe.

Today's young people...are they all working so hard?

The sweaty boy buried his head in calculations for a long time, then suddenly controlled his face excitedly, slapped his thigh suddenly and roared, scaring many people.

"By the way! Just use the combination of the Newton-Leibniz formula, Fermat's lemma, and Lagrange's three theorems! Finally, use the clamping theorem, and it's OK!"

Chicken eaters: "???"

Who the fuck can stand up and tell me what this person is talking about? !

Before everyone could think too much, they heard another slamming sound on the table.

"Wow! This topology test is really tricky!" A student who seemed to be just an adult from another direction was speaking,

Howling and rubbing his messy hair, "How do you solve the area of ​​the Lello triangle? Ahhh!!"

Chicken eaters: "???"

The chicken eating crowd looked at each other silently.

Did we... come to the wrong place...

They looked at the computer screen in front of them, full of deep guilt.

No, I feel too much guilt, I want to eat some chicken to slow down.

………………

On the other hand, Kyoto.

PBC Institute of Technology (Tsinghua University) school forum. Also known as Top Academic Discussion Group.

The elementary school scum of the research group: "Hey, where are the big masters, why don't you see them? I still have a question about Wilstrass function to ask him."

The grassroots of the discussion group: "You don't know yet, they are all doing a set of test questions now, they must be very busy, and they don't have time to deal with you, an elementary school scum. I still have a Mobius problem here, which is still in progress." Worry no one asked!"

Research group Xuehua: "I heard that, the seniors seem to have received the invitation letter from "The Most Powerful Brain". It seems that now is the time for the first round of testing."

Discussion group 20: "Wow, the seniors cheated. When will I become a man who is a top student?"

Research group Dong Dong: "I heard that a total of 100,000 places for the preliminary examination of "The Most Powerful Brain" have been issued this time, but only 100 people can participate in the recording in the end. I don't know how many people in our school can become the last 100 people."

Top student in the research group: "How much is good, as long as it is not less than the Yuanmingyuan Vocational and Technical College next door!"

Discussion group grass: "Reconsideration!"

Elementary school slag in the research group: "+1"

Good people in the research group: "+1"

…………

A large piece of reconsideration below.

………………

The camera returns to our classmate Cheng Nuo again.

Twenty minutes after the exam started, Cheng Nuo had reached the tenth question.

"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 pistols. Xiao Li's hit rate was 30%, Xiao Huang was better than him, with a hit rate of 50%, and finally The good shooter is Kobayashi who never makes a mistake and hits 100%. Because of this obvious fact, for the sake of fairness, they decided to follow this order: Xiaoli shoots first, Xiaohuang second, and Xiaolin last. Then cycle like this, Until there is only one of them left. So which of the 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.

It was also the only question that Cheng Nuo had done so far with a basic score of five.

Obviously, this question tests the contestant's reasoning ability, calculation ability, logical thinking ability, and... luck.

There are only three options in total. For some players, choosing one at random has a 33.33% correct rate. If you count it for a long time, the correct rate is 33.33%.

Cheng Nuo frowned and read the title.

The complexity of this question is indeed very troublesome. Good logical reasoning and computing skills are needed to avoid messing up the brain.

Who did Xiao Li shoot first, and did he hit him?

When it was Xiao Huang's turn, did Xiao Huang die, and if he didn't die, who would he shoot this shot at? Did you hit it? What happens when it hits, and what happens when it doesn't?

When it's Kobayashi's turn to shoot at the end, what are the chances that Kobayashi is alive? Who does he want to hit? Hit or miss?

Thinking about it this way makes my scalp tingle! !
