Chapter 142: Brother, I know you!

As we all know, a two-dimensional code is composed of black and white pixels.
　　 It is encoded by different distributions of black and white pixels in a matrix in a rectangular space. In the pixel position of the matrix, the appearance of dots represents a binary "1", and the absence of dots represents a binary "0". The permutation and combination of points determine the meaning of the QR code.
　　 At this time, what is displayed on the screen of Cheng Nuo's mobile phone is an incomplete QR code picture composed of black and white pixels.
　　 Cheng Nuo simply collected the data of this QR code picture.
　　 The area where the QR code picture is displayed in Cheng Nuo’s eyes is composed of 400 pixels.
　　 Among them, there are 214 black pixels and 186 white pixels.
　　 Then, Cheng Nuo used the exact center of the QR code picture as the origin to construct a coordinate system. Take each pixel grid as a unit.
　　 Then, the position coordinates of the 214 black pixels clearly appeared in Cheng Nuo's mind.
　　,...
　　 The coordinates of 186 white pixels are also:,,...
　　 After storing these four hundred sets of data in his brain, Cheng Nuo got up and walked towards the five hundred topological origami.
　　 At this time, the remaining 49 players are still observing the process of memory.
　　 It is worth mentioning here that in the challenge at this stage, the contestant is not allowed to hold a mobile phone to compare between 500 topological origami.
　　 is the same as the challenge in the first round. After the contestants have finished observing and remembering 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 ability, spatial ability, and reasoning ability.
　　 is also an extremely powerful test for the players' memory!
　　 After Cheng Nuo finished his memory for the first time and walked towards the 500 topological origami area, within ten seconds, Li Lingxiao also ended the memory stage and ran towards the topological origami area in small steps.
　　 Then, Li Shiye and He Youjun also memorized their respective QR code images and entered the search stage.
　　 Five hundred topological origami, two thousand completely different two-dimensional code expansion pictures.
　　 In the case that the most powerful brain program group only gives one-fifth of the effective information area, even a world memory master like Li Lingxiao dare not take it lightly.
　　 There is no problem with his memory. But the spatial imagination is relatively poor.
　　 So his strategy is to rely on strong memory first, and remember all the details of the QR code given in the title.
　　 Then, I quickly ran through five hundred topological origami. Eliminate options that are simply impossible.
　　Finally, using the space imagination to fold the topological origami, and do the final screening on the few suspected objects.
　　 Since it is only the first rough screening, he browses origami very quickly. Almost every second or two, you can finish reading a topological origami.
　　 On the other side, Li Lingxiao found that there was another voice almost as fast as his observation speed...
　　 That is Cheng Nuo!
　　 Li Lingxiao glanced slightly, watching Cheng Nuo's rate of one frame per second, and whispered, "That guy, is his strategy the same as mine?"
　　 In Li Lingxiao's view, Cheng Nuo's strategy is probably similar to his own.
　　 is the first rough screening, eliminating most of the impossible options.
　　 Then the second time, among the remaining options, find the topological origami that can fold the correct QR code picture.
　　 Thinking of this, Li Lingxiao settled his mind and no longer paid attention to Cheng Nuo, but instead focused all his energy on screening answers.
　　 To be honest, Cheng Nuo took first place in the first two times, and Li Lingxiao was very unconvinced.
　　As a master of world memory, no matter where he goes, is he not a brilliant existence?
　　 can happen...
　　 On this stage, his light was completely obscured by Cheng Nuo's scenery!
　　 In the two rounds, he became Cheng Nuo's background board.
　　 Since he was a child, he is very talented. How can he be convinced by the proud heart?
　　 "Cheng Nuo, in this round, let's see how I beat you!"
　　 Li Lingxiao clenched his fists, his fighting spirit was high, and there seemed to be flames burning in his chest.
　　 Time passed slowly by one minute and one second.
　　 In the "topological origami" room, more than 30 people have observed and remembered, and entered 500 topological origami to find the correct answer.
　　 In the observation deck, there are still a dozen people staring at the phone screen to remember. Because they don't have the chance to watch again, they can only remember as much as possible once.
　　The gap in memory level is undoubtedly revealed at this moment!
　　 If the memory ability is weak, it will waste a lot of time than other players in this link, resulting in an increase in total time.
　　 On Cheng Nuo's side, it wasn't actually what Li Lingxiao thought. It was gradually selected in two stages.
　　 But... every time you observe a topological origami, Cheng Nuo will quickly construct an identical topological origami in his mind, and fold it in both positive and negative ways. Generate four completely different QR codes.
　　 The first fifth area in the middle of the four different QR codes, with a total of 400 black and white pixel coordinates, will instantly appear in Cheng Nuo's mind.
　　 The coordinates of the black pixel position of the two-dimensional code No. 1: ……
　　 The coordinates of the black pixel position of the QR code No. 2: ……
　　 No. 3 QR code...
　　…………
　　 "Not this one." Cheng Nuo shook his head and walked to the next origami.
　　 Often, for a piece of origami, Cheng Nuo needs to compare four times to determine if there is any one of the four QR codes that he is looking for.
　　 To be honest, such a huge amount of calculation is a great test for ordinary people's brains.
　　 Fortunately, Cheng Nuo's brain has been upgraded, no matter how fast it runs, the graphics card will not burn.
　　 One origami paper per second, this speed is considered Cheng Nuo's normal level.
　　 When Li Lingxiao deliberately competed with Cheng Nuo, it could be said that the small universe broke out. The speed of the coarse screen in the first stage suddenly accelerated, reaching one per second.
　　 The challenge time came to the tenth minute.
　　 As of now, there is still no player who has completed the answer. This shows that the difficulty of this challenge is the most difficult of the three challenges!
　　 Li Lingxiao and Cheng Nuo, each of them only had more than ten photos to read them all.
　　 "It's you, Pikachu!"
The corners of Cheng Nuo’s mouth were bent, and his frowning face was replaced by joy~EbookFREE.me~ I looked at more than 480 topological origami papers, but I couldn’t find any origami that matched the coordinates, and even made Cheng Nuo wonder if he was right. One is missing.
　　 Fortunately, in the last dozen origami topological origami, Cheng Nuo found it.
　　 On the other side, Li Lingxiao has read all five hundred origami papers once.
　　 Sorting out the memories in his mind, he turned his head to look at Cheng Nuo, ready to observe the enemy.
　　 I saw, in Li Lingxiao's sight, Cheng Nuo took out the phone and tapped the phone screen easily.
　　 The next second, the room voice sounded.
　　 "The topological origami room came out first, Cheng Nuo, it took 10 minutes and 11 seconds!"
　　……
　　 still plays the voice three times.
"This……"
　　 Li Lingxiao was unstable, he staggered, and was shocked to the ground.
　　 "Didn't you say that you should observe it twice? Why do you just...get it done once?"
　　 "You're like this, I'm very shocked, okay!"
　　 Li Lingxiao complained silently in his heart.
　　 By coincidence, after the challenge was over, Cheng Nuo, who was about to leave, passed by Li Lingxiao.
　　 Seeing Li Lingxiao who fell on the ground, Cheng Nuo stopped, leaned down, cheered, "Brother don't cry, stand up!"
　　Li Lingxiao: "……"
　　 Li Lingxiao looked at He Youjun, who was avoiding Cheng Nuo like a snake and scorpion in the distance, and wanted to shout: Brother, I know you!
　　Li Lingxiao now finally understands how He Youjun felt at that time.
　　 Cheng Nuo, this guy is... poisonous!
