Omnipotent Data

As we all know, QR codes are composed of black and white pixels.

It is encoded by the different distribution of black and white pixels in the matrix in a rectangular space. On the pixel position of the matrix, the presence of a dot represents a binary "1", and the absence of a dot represents a binary "0". The arrangement and combination of dots determines the meaning represented by the QR code.

At this time, what appeared on the screen of Cheng Nuo's phone was an incomplete QR code picture composed of black and white pixels.

Cheng Nuo simply collected the data of this QR code picture.

The QR code image displayed in Cheng Nuo's eyes consisted of a total of 400 pixels.

Among them, there are 214 black pixels and 186 white pixels.

Then, Cheng Nuo built a coordinate system with the center of the QR code picture as the origin. Take each pixel grid as a unit.

Then, the coordinates of the 214 black pixels clearly appeared in Cheng Nuo's mind.

,,...

The coordinates of 186 white pixels are also:,,...

After storing a total of 400 sets of data in his brain, Cheng Nuo got up and walked towards the 500 pieces of topological origami.

At this time, the remaining 49 contestants were still in the process of observing and remembering.

It is worth mentioning here that in this stage of the challenge, contestants are not allowed to compare back and forth among the 500 topological origami with their mobile phones.

Instead, it is the same as the first round of challenges, after the contestants have finished observing and memorizing in the observation area, they need to press the "Start" button before they can go to the topological origami area to search for answers.

This project not only tests the observation, spatial and reasoning skills of the contestants.

It is also an extremely powerful test for the players' memory!

Less than ten seconds after Cheng Nuo completed the first memorization and walked towards the five hundred topological origami area, Li Lingxiao also finished the memory stage and ran towards the topological origami area in small steps.

Afterwards, Li Shiye and He Youjun also successively memorized their QR code images and entered the search phase.

Five hundred topological origami sheets, two thousand completely different QR code unfolding pictures.

With only one-fifth of the effective information area given by the strongest brain program group, even a world memory master like Li Lingxiao dare not take it lightly.

His memory is fine. But spatial imagination is relatively poor.

Therefore, his strategy is to first rely on his strong memory to memorize all the details of part of the QR code given in the question.

Then, go through the five hundred topological origami sheets quickly. Eliminate options that are simply not possible.

Finally, for the few suspected objects, the topological origami is folded through spatial imagination to make the final screening.

Since it was only a rough screening of the first step, he browsed the origami very quickly. Almost every second or two, you can read a piece of topological origami.

On the other side, Li Lingxiao discovered that there was another voice almost as fast as his observation speed...

That's Cheng Nuo!

Li Lingxiao glanced sideways, looked at Cheng Nuo's almost one-second speed, and muttered, "That guy, is his strategy the same as mine?"

From Li Lingxiao's point of view, Cheng Nuo's strategy was probably similar to his own.

First, the first rough screening to exclude most impossible options.

Then for the second time, among the remaining options, find the topological origami that can fold out the correct QR code picture.

Thinking of this, Li Lingxiao settled down, stopped paying attention to Cheng Nuo, and focused all his energy on screening the answers.

To be honest, Cheng Nuo took the first place in the first two times.

Li Lingxiao was very unconvinced.

As the master of world memory, no matter where he goes, isn't he a shining existence?

But unfortunately...

On this stage, his radiance was completely overshadowed by Cheng Nuo's beauty!

In the two rounds of competition, he became Cheng Nuo's background board.

How could he, who was gifted with extraordinary talent and extremely proud in his heart since he was a child, be convinced?

"Cheng Nuo, let's see how I beat you in this round!"

Li Lingxiao clenched his fists tightly, his fighting spirit was high, and there seemed to be a flame burning in his chest.

Time is slowly passing by every minute and every second.

In the "topological origami" room, more than 30 people have already observed and memorized, and entered the 500 sheets of topological origami to find the correct answer.

In the observation deck, there are still more than a dozen people staring at the phone screen to remember. Because they don't have the chance to watch it again, so they can only memorize it as much as possible at one time.

The gap in memory level is undoubtedly revealed at this moment!

If the memory ability is weak, it will waste a lot of time in this link compared with other players, resulting in an increase in the total time.

On Cheng Nuo's side, it was actually not what Li Lingxiao thought, and they were gradually screened in two stages.

Rather... Every time he observes a piece of topological origami, Cheng Nuo will quickly construct an identical topological origami in his mind, and fold the front and back respectively. Generate four completely different QR codes.

The coordinates of a total of 400 black and white pixels in the fifth area in the middle of the four different QR codes will instantly appear in Cheng Nuo's mind.

The position coordinates of the black pixels of the No. 1 QR code:, ...

The position coordinates of the black pixels of the No. 2 QR code:, ...

QR code No. 3...

…………

"Not this one." Cheng Nuo shook his head and walked to the next origami.

Usually, for a piece of origami, Cheng Nuo needs to compare it four times before he can confirm whether there is what he is looking for in the four folded QR codes.

To be honest, such a huge amount of calculation is a great test for the brain of ordinary people.

Fortunately, Cheng Nuo's brain has been upgraded, no matter how fast it runs, the graphics card won't burn out.

One origami paper per second, this speed is Cheng Nuo's normal level.

When Li Lingxiao intends to compete with Cheng Nuo, it can be said that the small universe exploded. The speed of the first stage of coarse screening suddenly accelerated, reaching one per second.

The challenge time came to ten minutes.

As of now, no contestant has completed the answer. It can be seen that the difficulty of this challenge is the most among the three challenges!

Li Lingxiao and Cheng Nuo were only a dozen or so away from reading all of them.

"It's you, Pikachu!"

The corner of Cheng Nuo's mouth curved, and the frowning on his face was replaced by joy.

After reading more than 480 topological origami sheets, they couldn't find one that matched the coordinates, and Cheng Nuo even wondered if he had missed one.

Fortunately, Cheng Nuo found it among the last dozen topological origami.

On the other side, Li Lingxiao has already read all the 500 origami sheets.

After sorting out the memories in his mind, he turned to look at Cheng Nuo, ready to observe the enemy's situation.

In Li Lingxiao's sight, Cheng Nuo took out his phone and tapped a few times on the screen with ease.

In the next second, the voice in the room rang.

"The first place in the topological origami room, Cheng Nuo, took 10 minutes and 11 seconds!"

...

The voice is still played three times.

"This……"

Li Lingxiao was unsteady, staggered and fell to the ground in shock.

"Didn't you agree to observe it twice? Why did you... get it done once?"

"You're such a blow to me, okay?"

Li Lingxiao complained silently in his heart.

Coincidentally, after the challenge was over, Cheng Nuo, who was about to leave, passed by Li Lingxiao.

Seeing Li Lingxiao on the ground, Cheng Nuo stopped, leaned over, and said cheeringly, "Brother don't cry, stand up and fuck!"

Li Lingxiao: "..."

Li Lingxiao looked at He Youjun who avoided Cheng Nuo like a snake and scorpion in the distance, and really wanted to shout: Brother, I understand you!

Li Lingxiao now finally understands He Youjun's feelings at that time.

This fellow Cheng Nuo is... poisonous!
