"who is this man

"I don't know, but he came here with Biden and Jerry. It should be a Cambridge student."

"It's strange that the students who can be sent by Cambridge University must be as famous as you and me, but I have never heard of such a person."

"I wonder. This guy seems to have jumped out of nowhere. He has no impression at all

Cheng Nuona's unusual behavior naturally attracted the attention of other college students.

When people stare at Cheng Nuo and discuss one after another, the door of the classroom is opened, and a man with elegant glasses and artistic long hair comes in with a woven bag in his hand.

"Hello, students. I'm Edward Shirley From the Ministry of education in Germany. I'll arrange your itinerary for the next three days." With a faint smile on his face, Mr. Edward introduced himself politely and haughtily.

Mr. Edward had a form in his hand, which was the schedule for the three days.

After a look, he said with a smile, "you are very lucky. This afternoon, the third generation of 5D film equipment developed by Professor corvor and five other professors will be on-the-spot screening, and then we can go and watch it."

Third generation 5D movie equipment?

Cheng Nuo's eyes brightened.

A few days ago, he spent a lot of money to watch a 5D movie device, which was just the first generation of 5D film equipment. But that kind of immersive feeling has already let Cheng Nuo exhale.

The third generation equipment Certainly not worse than the first generation.

Cheng Nuo found that he began to be interested in this exchange activity which had no expectations.

I thought it was just one competition after another, but I didn't expect to have "welfare" payment from time to time.

"But in the end, only five seats were allocated to our math major. So I'm sorry to say that of the 45 people here, only five of us will have the chance to watch the audio-visual feast brought by the third-generation 5D film equipment. "

"So, in order to be fair, I decided to choose five students to participate in through a small game."

As soon as Mr. Edward's voice fell, Cheng Nuo felt the temperature of the whole room drop several degrees.

There were serious expressions on the faces of all the people, and the strong sense of war in their eyes seemed to gush out.

They know that the first competition is coming!

As for the only five film viewing places, it's just a simple one.

In any case, they will not believe that the education departments of the two countries will join hands to arrange hundreds of positions.

In that case, in any case, they must seize one of the five places.

Not for the chance to watch 5D movies, but for not tarnishing the reputation of their famous schools.

5D movies can be watched later, but it's hard to pick up face loss.

I'm afraid that among the 45 people on the scene, Cheng Nuo is the only one who is simply for the rare opportunity to watch the film.

"Mr. Edward, what do we compare?" Some people were rubbing their hands on the scene, but they couldn't hold it. They looked directly at Mr. Edward and asked.

"Oh, don't say it's so gunpowder!" Edward waved his hand. "It's just a little game. Don't be so heavy about winning or losing. In fact, it's not necessary to win or lose. At most, those who don't get the quota can only stand outside the cinema and watch it. "

Standing outside the cinema, it would be humiliating to stand on the street for two hours.

Edward might as well not have said that.

All of them are favored by heaven. How can they tolerate being treated as animals in the zoo on the street. The others sat comfortably in the cinema.

Just like adding fuel to the fire, even those students whose desire to win or lose were not very strong were spurred by Edward's words.

If Edward hadn't explained the details of the game, someone would have pinched it right away.

Edward saw that the effect had been achieved. He nodded with satisfaction and took out the equipment for the competition from the woven bag in his hand.

So, when people look at the table placed on a disordered three-level magic cube, most of them are confused.

All of you are students majoring in mathematics. They know that the content of the competition must be related to mathematics. But when it comes to Rubik's cube, people really don't understand.

Edward took out a total of 45 Rubik's squares, placed them on the table in turn, then casually took one of them and said, "maybe you are all curious. What am I going to do with these Rubik's squares. Of course, I can't let you compete with the speed of restoration. That's what Rubik's cube masters need to do, not what we mathematicians need to do. "

"Well, I don't think some of them can hold their breath, so I won't sell the lawsuit. Forty five Rubik's squares have been disrupted by us in the same way. And your job is to restore the cube with the least number of turns possible"Mr. Edward, the answer is 20!" A student raised his hand high and said loudly, with his face empty, and looking at the crowd with his neck open, it seemed that he had won the prize.

"I know it's 20, of course." Mr. Edward couldn't help but scold, "I don't want a dry number, but a specific rotation process. Process!! Do you understand? What else do you do with this game if you have numbers! "

The student raising his hand was roared by Edward and shrunk.

"The time is limited to one hour, and the evaluation criteria are that less rotation times are preferred, if the rotation times are the same, who takes less time will be photographed in front of them." Mr. Edward was too lazy to say too much nonsense, and said in a straight breath, "now it's 9:36, the time begins!"

As the voice dropped, people took a magic square from the table, sat down in an empty position, and studied the magic cube.

Cheng Nuo was not slow, when everyone had finished, only one magic square left on the table, they put their mobile phones back in their pocket, held the magic square in their hands, turned their heads and looked at the rest of the students who had been thinking of magic square, and laughed silently.

Although Mr. Edward said it was just a small game, it was not simple at all, and even difficult.

And this game can be regarded as a comprehensive consideration of the mathematical level. If you don't think about it, even if you know that the standard answer is "20", it is hard to say that it can really restore the magic cube in 20 steps without ten years and eight years.

45.3 billion combinations are enough to make everyone daunting.
