"Super Sudoku Rubik's Cube! In this round, the topic you want to compete with is the Super Sudoku Rubik's Cube! What kind of problem is this, please talk to Wei to explain it to us. ”

The host opened the ball, and when he saw the title of the ball inside, he glanced at Miyayoshi and Qi Feng strangely. If he remembers correctly, this is the most difficult question of all the questions, and the host didn't expect his hands to be so black that he drew the most difficult question.

When he heard the host read this question, his face also changed. How difficult this question is, Na Wei knows very well in his heart, because this problem is improved from a world problem from a foreign Sudoku master, and it is said that no one has made a Sudoku problem at present, including the Sudoku master himself.

"How could this question be placed in this? This question is too difficult, let's draw a new question! It's meaningless than this question!" I also complained secretly in my heart, and I didn't know if it was the careless one, so I said that this question should not be put in the question bank, but I still put it in.

"Wait a minute, Dr. Wei, I think since I won the lottery, let's do this question! The problem is difficult to do, I am not afraid of the difficult topic, I believe I will definitely be able to do it! Of course, if Gong Guitar is going to find it difficult, it doesn't matter if you change the topic. Huh!"

Qi Feng When he heard that he had won the Super Sudoku Rubik's Cube, his brows jumped fiercely. He never dreamed that such a world-class problem would appear on the stage of "Super God Brain".

But Qi Feng will not be the first to coerce, the Rubik's Cube is one of Qi Feng's strengths, and Sudoku also has in-depth research, both of which are beneficial to himself. Looking at Miyaji, these two questions test the player's calculation, reasoning and spatial ability respectively, and have nothing to do with Miyaji's strong memory. Therefore, in Qi Feng's eyes, it is impossible for him to lose this question, and there is no reason to coax him first.

In this regard, Qi Feng stood up first and provoked Gong Ji, Gong Guitar will not change the topic if he has the ability, then he will die a miserable death.

"Yes, it's interesting when it's difficult! I've read too many simple questions in front of me, and I feel that my IQ has dropped a lot. If you want to find it difficult, I have no opinion on this question. Qi Feng He didn't expect it, and Gong Ji said without even thinking about it.

Obviously, Gong Guitar probably doesn't know how difficult this Super Sudoku Cube is.

"Talking Wei, is this question super Sudoku Rubik's cube difficult? Why don't you explain to us first, what is a super Sudoku Rubik's cube? It's the first time we've heard of it, how are this Sudoku and the Rubik's Cube connected?"

At this time, the guest Tao Ying stood up to reconcile the atmosphere, took over the conversation, and asked Wei to explain the topic of the competition.

"Well, since both of you had chosen this question, then we won't change it. However, this question is too difficult, it may take a long time, and it may not even be possible to solve it. Then I'll give you two hours, and decide the winner by the proportion of who completes the standard answer in the end, and that's no problem! Before the game, let me explain to you what is called a Super Sudoku Rubik's Cube, please look at the big screen!"

"This is a 3×3 Rubik's cube, you should have seen it, it is different from the ordinary Rubik's cube is that each side of the Rubik's cube has nine large grids, and each large grid is also a 3×3 Sudoku question, and the vacant part above needs to be filled in by the player. Looking at the whole picture, the standard answer is to ask the contestant to complete the Sudoku rule is to meet any row or any column, and it is to meet 1-9 numbers without repeating. The same is true for the other five sides of the Rubik's cube, and the really difficult part of this problem is that each large grid of the Rubik's cube can be changed at will. What the contestants need to do is not only to complete these empty Sudoku, but also to find the only solution to the six faces by switching the squares of the Rubik's cube. ”

You know, this kind of third-order Rubik's cube change, there are more than four trillion changes in total, and finding a solution that can satisfy the six-sided Sudoku rule requires a lot of computational reasoning and spatial ability. That's why I said that this super Sudoku Rubik's cube is a world-class problem, and it is tens of millions of times more difficult than the Sudoku or Rubik's cube we usually see!

Talking about Wei seeing that Gong Ji and Qi Feng were both so iron-headed, then he could only respect their choice and began to explain the rules of the Super Sudoku Rubik's Cube.

"Huh, four trillion variations......? This is too perverted, how could such a perverted topic be come up with? It's so exaggerated! It makes my scalp tingle when I hear it!" Guest Tao Ying exclaimed exaggeratedly, and couldn't help but worry about the two contestants, Gong Ji and Qi Feng.

It's great that half of the audience can understand, and even if they don't, they also know that this question is really perverted, and it is more difficult than the previous questions combined.

"Sure! That's it! Sounds okay, it's kind of interesting. But I still hope that the question will be more difficult in a while, it is too simple, and if you can see it at a glance, it will not be interesting. ”

It's the first time I've heard of this Super Sudoku Rubik's Cube, and I think it's quite interesting. But it's really as difficult as Wei said, but Gong Ji doesn't have to, and two hours is too much.

"Gong guitar is no problem, I naturally have no problem! I can start at any time!" Qi Feng's palms were sweating slightly, but it was because of excitement.

This guy Miyayoshi is really confident enough, I hope that when the game is over, he can still be so confident!

Qi Feng is also confident, thinking that he is confident that he can solve this problem within two hours. Even if it can't be completely solved, at least it will be much more complete than the palace guitar. Qi Feng is a player with very strong comprehensive strength, and the difference in each ability is about the same, this kind of question is simply tailor-made for him, and there is no reason to lose.

As soon as the host saw that there was no objection from both sides, then he announced that the two sides would sit in the preparation area, talk to Wei and the guests, and select a few audience members to come up on the spot, and work together to complete the question on the computer.

Five minutes later, a Super Sudoku cube puzzle was created and sent to a 21-inch touchscreen table in front of the two contestants. Under the host's order, the desktops in front of Miyayoshi and Qi Feng lit up at the same time, and a huge movable and rotatable virtual Rubik's Cube appeared.
