Chapter 440

"Who is this man?"

"I don't know, but the person he came here with Beaton and Jerry just now must be a student at Cambridge University. ”

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

"I'm wondering, too. This guy is like he suddenly popped out of nowhere, and he has no impression at all. ”

Cheng Nuo's unusual behavior naturally attracted the attention of students from other colleges and universities.

Just when everyone was staring at Cheng Nuo and discussing, the door of the classroom was opened, and a man with long wavy curly hair wearing Sven glasses and an artistic atmosphere walked in with a woven bag in his hand.

"Hello students, I am Edward Siri from the Ministry of Education of the German and Cuban countries, and I will 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 table in his hand, which was the formation schedule of the people for the past three days.

After one glance, he said to everyone with a smile on his face, "You are lucky that this afternoon, the third-generation 5D cinema equipment developed by Professor Corvo and five other professors will have a field screening, and we can go to see it live." ”

The third generation of 5D cinema equipment?

Cheng Nuo's eyes lit up.

A few days ago, he spent a lot of money to watch a 5D movie equipment, and it only used the first generation of 5D movie equipment. But that immersive feeling has already made Cheng Nuo addicted.

What about the third generation device...... It's certainly not worse than the first generation.

Cheng Nuo found that he began to become interested in this exchange event, which he had little expectation.

I thought it was just one competition after another, but I didn't expect that there would be "benefits" from time to time.

"However, in the end, there were only five seats allocated to our math major. Therefore, I can only apologize to say that only five of the 45 of us here have the opportunity to watch the audio-visual feast brought by the third-generation 5D cinema equipment. ”

So, for the sake of fairness, I decided to select five students to participate in the competition through a small game. ”

As soon as Mr. Edward's voice fell, Cheng Nuo clearly felt that the temperature of the entire room had dropped by several degrees.

Everyone had serious expressions on their faces, and the strong battle intent in their eyes seemed to be gushing out.

They know that the first competition is coming!

As for the fact that there are only five viewing places, it is just a simple reason.

In this case, they will not believe that the education departments of the two countries will join forces, and they will not even be able to arrange hundreds of places.

In this case, no matter what, they must grab one of those five places.

Not for the opportunity to watch a 5D movie, but for not to ruin the fame of their prestigious school.

5D movies can be watched later, but it is difficult to pick them up again if you lose face.

I'm afraid that among the forty-five people at the scene, only Cheng Nuo was just for that rare opportunity to watch the movie.

"Mr. Edward, what are we comparing to?" someone at the scene was already gearing up, and couldn't help it, so he looked directly at Mr. Edward and asked.

"Well, don't say it smells of gunpowder!" Edward waved his hand, "It's just a little game, don't be so serious." In fact, it is not much necessary to win or lose, at most those who do not get a place can only stand outside the theater and watch. ”

Standing outside the theater and watching it, wouldn't it be a shame to stand on the street, and it was still two hours.

Edward might as well not say this.

All of them are the pride of the sky, how can they tolerate being treated as animals in the zoo by others on the street and being watched and teased. And a few others sat comfortably in the theater watching movies.

It was like adding fuel to the fire, even those students who did not have a strong desire to win were all in the blood of Edward's words.

If it weren't for Edward's lack of clarity about the specific content of the game, it is estimated that someone would have pinched it directly.

Seeing that the effect had been achieved, Edward smiled and nodded with satisfaction, and took out the tools for this competition from the woven bag in his hand.

So, when everyone looked at the disrupted third-order Rubik's cubes on the table, most of them were confused.

All of you here are math majors, and they know that the content of the competition must be related to math. But when it comes to the Rubik's Cube, everyone really doesn't understand.

Edward took out a total of forty-five Rubik's cubes, placed them on the table in turn, and then took a random Rubik's cube and said, "Maybe you are a little curious, what am I going to do with these Rubik's cubes." Of course, I definitely can't let you compete with the speed of restoration, that's what the Rubik's Cube master needs to do, not what we mathematicians have to do. ”

"Okay, I see that a few of them can't hold back anymore, so I won't sell the lawsuit. Forty-five Rubik's cubes, which have been disrupted by us following the same steps. And your job is to restore the Rubik's Cube with the least number of rotations possible. ”

"Mr. Edward, the answer is 20!" said one of the students with his hands raised in a high voice, his face fluttering, and his neck held high, as if he had won the battle.

"Of course I know it's 20. Mr. Edward couldn't help but scold, "I don't want a dry number, but a specific turning process." You know, if it's just numbers, why are you doing this game!"

The student who raised his hand was yelled at by Edward's neck shrinking.

"The time limit is one hour, and the criterion for evaluation is that the number of turns is less priority, and if the number of turns is the same, whoever takes less time will shoot in front. Mr. Edward didn't bother to say too much nonsense, and said directly in one breath, "It's 9:36 now, and the timer begins!"

As soon as the words fell, everyone stepped forward and took a Rubik's Cube on the table, found an empty place to sit down, and kept studying the Rubik's Cube.

Cheng Nuo was unhurried, and when everyone had finished taking it and there was only one Rubik's Cube left on the table, he put the mobile phone back in his pocket, took the Rubik's Cube in his hand, turned his head and glanced at the rest of the students who were holding the Rubik's Cube and thinking hard, and laughed silently.

Although Mr. Edward said that this was a small game, the game was not at all simple, and could even be said to be quite difficult.

And this game,It can indeed be regarded as a comprehensive consideration of the level of mathematics,If you don't use your brain,Even if you know that the standard answer is "20", it is difficult to say that you can really restore the Rubik's Cube in only twenty steps without ten or eight years.

There are 452.3 billion combinations, which is enough to daunt everyone.
