Omnipotent Data

The statement also naturally noticed that Cheng Nuo was looking at him.

He threw the Rubik's Cube in his hand into the air, held it firmly in his hand, and raised his eyebrows at Cheng Nuo proudly.

"Can you play Rubik's Cube?"

Cheng Nuo smiled, "A little bit."

Cheng Nuo was indeed obsessed with the Rubik's Cube for a while.

From the second-order Rubik's Cube to the seventh-order Rubik's Cube, you can play a little bit.

However, the level is limited to being able to restore it according to the online tutorials.

And as for speed...

Cheng Nuo remembered that the fastest solution speed of his third-order Rubik's Cube seemed to be more than 30 seconds, which was not too far behind a real Rubik's Cube master.

There was an imperceptible look of joy in Chen Chen's eyes, and he said casually, "Cheng Nuo, since we are both in the top 200 players with the most powerful brains, why don't we... how about a comparison?"

"It's like Rubik's Cube, and I won't take advantage of you. You use both hands, and I use one hand. How about it?"

Statement looked at Cheng Nuo expectantly.

"It's not good." Cheng Nuo folded his arms and continued to find a comfortable position to lean against the back of the chair.

The statement was obviously bullying Cheng Nuo for not understanding the market.

Although the third-order one-handed twisting is much more troublesome than the third-order speed twisting, but for a real master, the speed of the third-level one-handed twisting is at most about 3 or 4 seconds slower than the third-level speed twisting.

Take my country's Rubik's Cube record as an example.

The third-order speed twist is 5.19 seconds, and the third-order one-handed is 8.27 seconds.

Both records were set by the same person.

With Cheng Nuo's scumbag speed of 30 seconds, he would be beaten by a one-handed statement.

"Come on, come on, student Cheng Nuo, it's so boring on the plane, why don't you play?" It's a difficult opportunity to pretend, and Chen Chen feels that he must seize it.

"No!" Cheng Nuo turned his head away and said extremely arrogantly.

"A meal!" Statement raised a finger, "As long as you win, I will invite you two to dinner tonight, and I will invite you to eat whatever you want!"

"Okay, deal!" Cheng Nuo grinned, revealing a harmless smile.

A plain meal, I must grasp it!

"But..." Cheng Nuo's voice changed abruptly. "We don't play Tier 3! Tier 3 is too simple and boring."

Statement with a confident face, "Then how many levels do you want to play, I will accompany you at any time."

"Then what is the highest level you are carrying now?"

"The seventh-order Rubik's Cube." After searching in his backpack for a while, the statement took out a seventh-order Rubik's Cube that was a few sizes larger than the third-order Rubik's Cube.

The seventh-order Rubik's Cube is composed of 218 squares. Due to geometric restrictions, the surface is arc-shaped. The price ranges from more than one hundred yuan to more than one thousand yuan.

The total number of its changes is 1.95*10^160.

Cheng Nuo had a nonchalant expression on his face, "Then we'll compete on the seventh level."

"That's impossible." Chen Chen shook his head, "I can't play the seventh-order Rubik's Cube with one hand."

Let alone a statement, even if you call the world's top Rubik's Cube masters, there is no way to restore the seventh-order Rubik's Cube with one hand.

because……

This thing is so big!

You can barely hold it with one hand, so you don't need to think about it.

"I'm not asking you to do it with one hand. We both use both hands to see who can do it faster." Cheng Nuo shrugged.

"Sure?"

"Sure, and sure."

"Then who will come first?"

"You come first, I will brew it first."

Statement handed the Rubik's Cube to Cheng Nuo, "Okay, I'll go first, you mess up the Rubik's Cube."

"I'll come, I'll come..." Jiang Jun, who had been watching all this, intercepted the Rubik's Cube from mid-air unceremoniously, brushed it a few times, and then disrupted the Rubik's Cube.

Six faces, six colors of yellow, white, blue, green, red and orange, a total of 218 squares, completely disrupted into no pattern at all.

timing,

start!

Cheng Nuo turned on the stopwatch on his phone and started counting.

As the champion of the seventh-order speed twisting in the College Student Rubik's Cube Open last year, his strength is of course not covered.

As soon as he got the Rubik's Cube, he took a second or so to look at the six sides first.

Then he lowered his head, and his slender fingers danced nimbly on the Rubik's Cube.

The crunching sound of the Rubik's Cube spinning rang in Cheng Nuo's ears.

The reduction formula of the seventh-order Rubik's cube is very complicated, and the reduction formulas of the fourth-order and fifth-order Rubik's cubes are also required, which requires a high brain speed for presentation.

When playing the third-order Rubik's Cube, the speed of the hand cannot keep up with the speed of the brain.

And when it comes to the seventh-order Rubik's Cube, the speed of the brain cannot keep up with the speed of the hands.

This is a phenomenon common to all Rubik's Cube players.

Cheng Nuo saw the numbers on the stopwatch beating non-stop.

30 seconds... 60 seconds... 90 seconds...

The expression of the statement was as usual, and the hands continued to rotate the Rubik's Cube tirelessly.

However, every once in a while, the statement has to stop for about a second or two, to sort out my thoughts, and then continue to solve the Rubik's Cube.

The restoration of the seventh-order Rubik's Cube is a huge and complicated project!

"call--"

Tens of seconds later, Chen Chen took a breath and rotated the top layer 270 degrees clockwise.

So far, all six faces of the seventh-order Rubik's Cube have been restored.

Time spent... 2 minutes 58 seconds 66.

"Not bad." Seeing this time, Chen Chen said with a smile.

The world record for the seven-step speed twist is 2 minutes 06 seconds 73.

The statement can reach 2 minutes and 58 seconds, which can already be regarded as a normal performance.

Chen Chen randomly twisted the restored Rubik's Cube a few times, messed it up, and threw it to Cheng Nuo, "It's your turn."

"Time it." Cheng Nuo said lightly.

Timing begins!

When the statement pressed the timer, Cheng Nuo's eyes looked at the Rubik's Cube in his hand, and groups of data flashed by.

The side length is 7.75 cm, the weight is 185.28 grams, the number of cubes is 49 on the first layer, and 218 in total on the second layer.

The number of yellow squares on the R layer is 5, and the position coordinates are (1, 2) (5, 2)...

The number of white squares in the R layer...

…………

The number of yellow squares on the L layer is 11, and the position coordinates...

…………

In less than a second, Cheng Nuo's eyes were like a scanner, collecting all the data of the scrambled seventh-order Rubik's Cube into his brain.

Then, build the Rubik's cube model in your head. Automatically calculate the recovery plan.

In the first step, the U layer is rotated 90 degrees clockwise.

In the second step, the R layer is rotated 270 degrees counterclockwise.

In the third step, layer B is rotated 90 degrees counterclockwise.

…………

The fifty-sixth step, L layer homeopathic station rotates 90 degrees.

…………

Why didn't Cheng Nuo choose and state the third-order Rubik's Cube for the competition?

That's because Cheng Nuo's hand speed couldn't keep up.

He has no special training, even if the brain calculates all the solutions to the third-order Rubik's Cube, if the hand speed cannot reach it, it is inevitable that he will lose to the statement.

But the seventh-order Rubik's Cube is different.

Brain speed is far more important than hand speed.

In the process of restoring the seventh-order Rubik's Cube, Cheng Nuo didn't have to worry about not having enough brains.

All he needs to do is follow the restoration steps calculated by his brain and restore it as quickly as possible.

In the eyes of the statement, Cheng Nuo's hand speed was not fast, even for a Rubik's Cube master like him, this hand speed was simply too slow!

Can……

What he couldn't believe was that Cheng Nuo didn't get stuck in the middle of the restoration. It was as if the restoration process had been simulated in my mind long ago.

"All right!"

While the statement was still in a daze, Cheng Nuo put the Rubik's Cube in front of the statement.

Take a look at the statement.

Six faces, all restored!

"By the way, how long did I use it?" Cheng Nuo looked at the statement.

The statement looked down at the stopwatch he had pressed to pause, "Your time is..."

...coastline...
