Chapter 141 (1/2)

As we all know, two-dimensional code is 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. In the pixel position of the matrix, the binary ”1” is represented by the appearance of dots (square dots, dots or other shapes), and the binary ”0” is represented by the absence of dots. The arrangement and combination of points determine the meaning of the two-dimensional code.

At this time, what is shown on the screen of Cheng Nuo's mobile phone is an incomplete two-dimensional code picture composed of black and white pixels.

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

The QR code image is displayed in the area of Cheng Nuo's eyes, which is composed of 400 pixels.

There are 214 black pixels and 186 white pixels.

And then we construct the two-dimensional coordinate system with the origin as the center. Each pixel grid is taken as a unit.

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

（1，25），（3，13），（21，21）……

The coordinates of 186 white pixels are also: (12,3), (21,6)

After storing 400 sets of data in his brain, Cheng gets up and walks to the 500 origami sheets.

At this time, the remaining 49 players are still observing the process of memory.

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

It is the same as the challenge of the first round. After the players observe and memorize in the observation area, they need to press the ”start” button to search for answers in the topological origami area.

This project is not only a test of the players' observation, space and reasoning.

It is also a powerful test for the players' memory!

After Cheng Nuo finished his first memory and walked to the 500 Tuo origami area, less than 10 seconds later, Li Lingxiao also finished the memory stage and ran to the topological origami area in small steps.

Later, Li shiye, he Youjun also successively memorized their two-dimensional code images and entered the search stage.

500 pieces of Topo origami, 2000 pieces of completely different QR code expansion pictures.

Even world memory masters like Li Lingxiao dare not take it lightly when the strongest brain program group only gives one fifth of the effective information area.

He has no problem with his memory. But the spatial imagination is relatively poor.

Therefore, his strategy is to rely on a strong memory, part of the title of the two-dimensional code, as far as possible to remember all the details.

Then, 500 pieces of origami are quickly passed through. Exclude options that are not possible at all.

Finally, in those suspected objects, the topological origami will be folded through spatial imagination to make the final selection.

Because it is only the first step of rough screening, so he browse origami very fast. Almost every one or two seconds, you can read a topological origami.

On the other side, Li Lingxiao found that there was another voice which was almost as fast as his own observation speed

That's Cheng Nuo!

Li Lingxiao slightly sideways, looking at Cheng Nuo's speed of almost a second, whispers, ”that guy, is his strategy the same as mine?”

In Li Lingxiao's opinion, Cheng Nuo's strategy is similar to his own.

First, the first coarse screening, excluding most of the impossible options.

Then the second time, in the remaining options, find the topological origami that can fold out the correct QR code image.

Thinking of this, Li Lingxiao settled down and stopped paying attention to Cheng Nuo. Instead, he put all his energy into screening the answers.

To tell the truth, Cheng Nuo took the first two times, Li Lingxiao is very unconvinced.

As a master of world memory, no matter where he goes, he does not exist in splendor?

But

On the stage of ”the strongest brain”, his light is completely covered by Cheng Nuo's scenery!

Two rounds of competition, he has become Cheng Nuo's background board.

Since childhood, he was gifted and extremely proud. How can he be convinced?

”Cheng Nuo, this game, see how I beat you!”

Li Lingxiao clenched his fists with high morale. There seemed to be a flame burning in his chest.

Time is slowly passing by in minutes and seconds.
