Omnipotent Data

Hey, hey!

Brothers meet again, three bowls of wine!

Brothers talk, two cups of tea!

…………

Cheng Nuogao sat in the seats, looking at his 99 "little brothers", he instantly felt heroic.

He felt like the timely rain Song Jiang in the Water Margin, with four big characters written on the banner flying high outside: The strongest brain!

Then he picked up the wine bowl and shouted loudly: "Come on, after drinking this bowl of aunt's blood, we will be brothers from now on!"

That scene, tsk tsk...

…………

After more than half an hour of recording, the part of announcing the ranking finally came to an end.

Cheng Nuo also had a general understanding of the 100 contestants.

College students are the main group, with a total of 65 people.

Among them, there are 12 from Tsinghua University and 15 from Peking University. The remaining 38 are also from top domestic or foreign universities.

There were 24 high school students, including Cheng Nuo.

There are 5 middle school students.

There are 6 elementary school students.

What Cheng Nuo didn't expect was that there were more elementary school students than middle school students.

Sure enough, we are all old after 00!

Now it is the world of the post-10s.

…………

Cheng Nuo, He Youjun, and Li Lingxiao sat at the highest place like a big man.

The remaining ninety-seven people looked at the three people on the top with unconvinced expressions on their faces.

Shout out, blow up, let you sing out first.

When the Top 30 is re-ranked, I don't believe that the three of you can still sit firmly on it.

"Okay. Now that everyone knows their rankings, please get ready, we will immediately enter the first challenge!"

"In this round, thirty contestants will be eliminated."

"What will your challenge project be? Please look at the big screen!"

On the big screen in front of everyone, the items and rules of the first round of challenges were displayed.

"Blind Sudoku!"

Sudoku is a brain-training game that everyone often plays. The rule is to make each row, each column, and each grid contain numbers from 1 to 9 based on the known numbers.

The strongest brain program group has upgraded the 9*9 Sudoku that we often play, and it has become the first challenge for contestants.

First of all, the place to upgrade is the size of Sudoku.

Usually the size of the Sudoku we play is 9*9, but this time the program group directly upgraded the size to 16*16.

Then the second upgrade is: blind filling!

After the player memorizes the initial number given in the box, the number in the box will be hidden.

Moreover, during the answering process, the entire 16*16 grid does not display numbers at all. Even if you filled in the number before, it will not be displayed in the box.

That is to say, if a player makes a memory error in one place, it will cause...the whole game will be lost!

For the third upgrade, the contestants need to fill in the 256 squares, not only the numbers from 1 to 14, but also 14 colors.

Numbers and colors are not in one-to-one correspondence.

In other words, contestants need to complete two separate sets of Sudoku questions in the case of blind filling!

The difficulty is more than twice that of just filling in the numbers.

The six-digit ability radar chart of the blind Sudoku project: 3.85 points for reasoning, 3.65 points for calculation, 1.24 points for observation, 3.98 points for memory, 1.57 points for creativity, and 1.42 points for spatial ability.

"Everyone, are you ready?" Teacher Jiang said to everyone in a serious voice,

"What I need to remind you is that you only have one chance to challenge. Failure means leaving this stage. Even if there are less than 70 people who succeed in the final challenge, only those who succeed in the challenge can advance to the next round."

Teacher Jiang's meaning is obvious, the failure of the challenge means elimination! There is no room for maneuver.

The knockout system is so cruel.

Everyone nodded in unison, and then, led by the staff, entered a closed room.

In the room, one hundred tables are neatly arranged. A serial number from 1 to 100 is pasted on it.

On every table, there is an ipaid.

Treacherous and inhumane!

One hundred people sat in their respective seats according to the initial ranking. Open the ipaid on the desktop according to the prompt of the broadcast in the room.

Cheng Nuo was sitting in the first position against the wall, behind him was He Youjun who ranked second, and behind him was Li Lingxiao who ranked third.

"...After memorizing, press the 'Start' button at the bottom of the screen to enter the blind filling mode. After answering, press the 'OK' button to complete the answer!"

After the specific operation is played, a countdown number of ten seconds will appear on everyone's ipaid screen.

In this challenge, everyone has the same topic, so there is no such thing as luck.

... 3! 2! 1!

Everyone's screens flashed, and a 16*16 grid appeared.

Among the 256 squares, 24 squares have been filled with numbers, and 24 squares have been filled with colors.

Seeing this, Cheng Nuo couldn't help but frown.

The most powerful brain's dismounting... It's really ruthless!

For 16*16 Sudoku, the number 24 has its special meaning.

If the number of numbers given by the condition is less than 24, it means that there is more than one correct way to fill in this Sudoku. It will be more selective.

Given more than 24 conditional numbers, although the correct answer is unique, due to the increase in conditional numbers, it will be very simple to do.

However, 24 prompt numbers are given, which is the most difficult way to make questions in Sudoku with 16*16 specifications, none of them!

Cheng Nuo smiled faintly, and quickly memorized the known numbers and colors given on the screen.

Still the same way, converting colors into numbers is not too simple.

Number: 8, location coordinates:

Number: 2, location coordinates:

…………

Color: white, location coordinates:

…………

There were a total of 48 sets of data, and it took Cheng Nuo less than five seconds to memorize all of them.

Press the "Start" button, the picture on the screen flashes suddenly, and sure enough, all the numbers and colors on the screen disappear. Only the 16*16 grid drawn with black and white lines remains.

And in an area on the right side of the screen, numbers from 1 to 14 are listed, as well as 14 colors such as red, orange, and yellow.

Cheng Nuo clicked on one of the 256 squares, and then clicked on a number on the right, which meant that Cheng Nuo would fill in the clicked number in that square.

In fact, there are many ways to fill in Sudoku, and Cheng Nuo chose the relative probability method that suits him best.

With the calculation amount of my own brain, the calculation intensity of this method is not a problem at all.

As for memory...

With Cheng Nuo's sensitivity to numbers, he didn't need to worry about filling in the numbers and forgetting them.

Cheng Nuo didn't know the strength of the other players, so his hand speed was so fast that it flew up.

Cheng Nuo filled in the boxes one by one with each number and each color.

On the other side, He Youjun, who was sitting just behind Cheng Nuo, had just memorized the corresponding positions of the 48 numbers and colors in the grid. When he moved his fingers and was about to start blind filling, he suddenly heard the sound of a chair moving in front of him.

He Youjun looked up with doubts in his eyes, only to see Cheng Nuo who was sitting in front of him standing up slowly and relaxed.

Seeing He Youjun looking up at him, Cheng Nuo smiled kindly and made a cheering gesture, "Come on!"

At this time, a voice broadcast came from the radio in the room.

"The first place in the blind fill-in Sudoku project, Cheng Nuo, took 1 minute and 58 seconds!"

"The first place in the blind fill-in Sudoku project, Cheng Nuo, took 1 minute and 58 seconds!"

...

The voice is played three times in a row. Everyone in the room can hear clearly.

He Youjun looked at Cheng Nuo who was making a cheering gesture to him: "..."
