Chapter 138: Blind Sudoku

Hehe, haha!
　　 Brothers meet, three bowls of wine!
　　 Brothers on Tao, two cups of tea!
　　…………
　　 Cheng Nuogao sat down on you, looking at his 99 "little brothers", instantly feeling a sense of heroism in his heart.
　　 He feels like Shiyu Songjiang in the Water Margin, and the flags flying high outside write four characters: the most powerful brain!
　　 Then he picked up the wine bowl and shouted loudly: "Come on, I've done this bowl of aunt's blood, we will be brothers in the future!"
　　 That scene, tut tut...
　　…………
　　 After more than half an hour of recording, the announcement of the ranking is finally over.
　　 Cheng Nuo also got a general understanding of the situation of these 100 players.
　　 University students are the main group, a total of 65 people.
　　 12 of them are from Tsinghua University and 15 from Peking University. The remaining 38 people are also from top universities at home or abroad.
　　 24 high school students, including Cheng Nuo.
　　 5 middle school students.
　　 6 elementary school students.
　　 What Cheng Nuo did not expect was that the number of elementary school students was more than that of middle school students.
　　 As expected, we are all old after 00!
　　 is now the world after 10.
　　…………
　　 Cheng Nuo, He Youjun, and Li Lingxiao sat on the highest point in a sitting posture.
　　 The remaining ninety-seven people looked unconvinced at the three people on the heights with a beating expression.
　　 嘚Se, 嘚Se, let you 嘚Se first.
　　 When the top 30 is re-ranked, I don’t believe you three can still sit on it.
　　 "Okay. Now that everyone knows their rankings, please be prepared, we will immediately enter the first level of challenge!"
　　 "In this round, thirty players will be eliminated."
　　 "What will your challenge project be? Look at the big screen!"
　　 On the big screen in front of everyone, the items and rules of the first round of challenge are displayed.
　　 "Blind Sudoku!"
　　 Sudoku is a kind of brain training game that everyone often plays. The rule is to make every row, every column, and every grid number contain 1-9 based on the known numbers.
　　The most powerful brain program group has upgraded the 99 Sudoku that we often play, and turned it into the first challenge of the players.
　　 First of all, the upgrade is the size of Sudoku.
　　The size of the Sudoku we usually play is 99, but this time the program group directly upgraded its size to 1616.
　　The second place to upgrade is: blind fill!
　　 After the player memorizes the initial number given in the square, the number in the square will disappear.
　　 Moreover, when the contestant is answering, the entire 1616 square does not show numbers at all. Even the numbers you filled in before will not be displayed in the grid.
　　In other words, if a player makes a mistake in memory, it will cause...all the game to lose!
　　 In the third place to level up, players need to fill in 256 squares, not just numbers from 1 to 14, but also 14 colors.
　　The numbers and colors do not correspond one-to-one.
　　In other words, the contestant needs to complete two sets of separate Sudoku questions in blind fill!
　　The difficulty is more than twice that of just filling in numbers.
　　Blind Sudoku Project's six-digit ability radar chart: reasoning ability 3.85 points, computing power 3.65 points, observation ability 1.24 points, memory ability 3.98 points, creativity 1.57 points, spatial power 1.42 points.
"Everyone, are you ready?" Teacher Jiang said to everyone in a serious voice, "I need to remind you that you only have one chance to challenge. Failure means leaving the stage. Even if there are fewer than 70 successful people in the final challenge, Only those who challenge successfully can advance to the next round."
　　Ms. Jiang's meaning is very obvious. Failure to challenge means elimination! There is no room for maneuver.
　　 The knockout system is so cruel.
　　 Everyone nodded, and then led by the staff into a closed room.
　　 In the room, one hundred tables are neatly placed. The serial number from 1 to 100 is pasted on it.
　　 There is an ipaid on every table.
　　壕 inhumanity!
　　 One hundred people sit in their seats according to the initial ranking. Open ipaid on the desktop according to the prompts broadcast in the room.
　　 Cheng Nuo is sitting in the first position against the wall, behind him is He Youjun, who is second, and Li Lingxiao, who is third.
　　"...After the memory is completed, press the ‘start’ button at the bottom of the screen to enter the blind filling mode. After the answer is over, press the ‘OK’ button to complete the answer!"
　　After the specific operation was played, a ten-second countdown number appeared on everyone's ipaid screen.
　　This challenge is the same for everyone, so there is no problem of luck.
　　...... 3! 2! 1!
　　 Everyone's screen flashed, and a 1616 grid appeared.
　　 Within 256 squares, 24 squares are filled with numbers, and 24 squares are filled with colors.
　　 Seeing this, Cheng Nuo frowned.
　　 The most powerful brain, this one gets off the hook... It's really ruthless!
　　 For 1616 Sudoku, the number 24 has a special meaning.
　　 If the number of digits given by the condition is less than 24, it means that there is more than one correct way to fill this Sudoku. It will be more selective.
　　 provides more than 24 conditional numbers. Although the correct answer is unique, it will be easy to do as the conditional numbers increase.
　　 However, 24 hint numbers are given. This is the most difficult way to make a question in 1616 Sudoku. There is no one!
　　 Cheng Nuo smiled faintly, and quickly memorized the known numbers and colors on the screen.
　　 It’s still the same method, it’s not too simple to convert colors into numbers.
　　Number: 8, location coordinates:
　　Number: 2, Location coordinates:
　　…………
　　Color: white, location coordinates:
　　…………
　　 A total of 48 sets of data, Cheng Nuo only took less than five seconds to memorize them all.
　　 Press the "Start" button, the picture on the screen flashed suddenly, and as expected, all the numbers and colors on the screen disappeared. Only 1616 squares drawn with black and white lines are left.
　　 In the area on the right side of the screen, there are 1~14 numbers listed ~EbookFREE.me~ and 14 colors such as red, orange, and yellow.
　　 Cheng Nuo clicks one of the 256 squares, and then clicks a number on the right, it means Cheng Nuo fills the clicked number into the square.
　　 In fact, there are many ways to fill in Sudoku. Cheng Nuo chose the relative probability method that suits him best.
　　 Given the amount of calculations in my brain, the computational intensity of this method is not a problem at all.
　　 As for memory...
　　 With Cheng Nuo's sensitivity to numbers, there is no need to worry about the problem of forgetting after filling in the numbers.
　　 Cheng Nuo didn't know what the strength of the other players was, so he soared to fly.
　　 Numbers and colors were filled in the squares by Cheng Nuo.
　　 On the other side, He Youjun, who was sitting behind Cheng Nuo, had just memorized the positions of the 48 numbers and colors in the square. 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 raised his head with doubts in his eyes, and saw Cheng Nuo sitting in front of him slowly standing up.
　　 Seeing He Youjun raising his head to look at him, Cheng Nuo showed a kind smile and made a cheering gesture, "Go on!"
　　 At this time, a voice announcement came from the broadcast in the room.
　　 "The first place in the blind Sudoku project came out, Cheng Nuo, it took 1 minute and 58 seconds!"
　　 "The first place in the blind Sudoku project came out, Cheng Nuo, it took 1 minute and 58 seconds!"
　　……
　　 The voice played three times continuously. Everyone in the room can hear clearly.
　　 He Youjun looked at Cheng Nuo who was making a cheering gesture to him: "..."
