Wang Xueba System

At the same time, the audience on the TV was also in an uproar. After all, no one could have imagined that Luo Hao could be so fast.

Through the TV, the discussion in the auditorium can be heard through the reduced sound processing.

"So fast again?"

"What kind of brain is this?"

"I don't know if he does anything else just as fast."

"What do you mean?"

"It's nothing interesting, just to praise him for his quick movements, don't think too much about it."

............

In the living room, Luo Hao was a little embarrassed when he heard this conversation. These people are all old drivers. On the surface, they haven't said anything that can't be broadcast. It's enough...

Luo Hao carefully looked at Huang Xi and his mother, and found that Huang Xi was fine and didn't respond, but the corners of Luo's mother turned up slightly and did not speak.

Luo Hao: (っ╥╯﹏╰╥c)

"What's this called?" Luo Hao wailed in his heart.

On the competition stage, because Hu Bin just failed the first question, he lost the opportunity to do the second question, so he watched the second question quietly from the sidelines.In my mind, I was also nervously thinking about how to do this question if I were replaced by myself.

As a result, when he was thinking hard, he found that Luo Hao had already finished it.

He opened his mouth wide and stared at Luo Hao dumbfounded, his eyes were shocked besides shock.

If you give him some time for this kind of topic, he can guarantee that he can do it, but if he is asked to do it so quickly, it is basically impossible.

After all, Hu Bin had never seen such a problem before.

Looking at Zhang Yi next to him who was still trying to answer, Hu Bin showed a touch of sympathy, but also a glimmer of hope.

As mentioned in the title, the winner is calculated according to the number of operations with the least number of operations first, and the time is second.

Hu Bin looked at the big screen, and there was no simultaneous display of the number of operations of the two of them. I guess this is also to leave everyone in suspense, right?

Zhang Yi on the side was thinking carefully. After all, the rule of this question is that the one with the fewest operations wins, so he must minimize the number of useless operations.

Zhang Yi held a capacitive pen in his hand, and every click on the answering board was the result of his deliberation.

He also discovered some rules for this question. Inspired by Luo Hao's explanation of the first question just now, he is also solving according to that rule.

If the audience at the scene were careful enough, they would find that Zhang Yi and Luo Hao's operation methods were completely different.

"Hey, Xiaohao, Zhang Yi's operation method seems to be the same as what you just said?" Huang Xi said suddenly, "It is also using the next line, first complete the operation of the previous line, and finally process the last line. At that time, I did not Pay attention, I only found out after you said that."

"But it seems that his last line is not that easy to deal with? Besides, how do I remember that your operation during the game is different from what you just said?" Huang Xi looked at Luo Hao.

"That's right, the method I just mentioned is the easiest to think of, and it's also the easiest way for people to think that this is the method that can complete the problem with the least number of steps." Luo Hao smiled with strong confidence in his smile, "But This minimum number of steps will be affected when it reaches the last row, because the last row will not be all lit up as we hoped."

"So this involves another kind of thinking, one's own calculation power." Luo Hao looked at Huang Xi, "Use a simpler 3x3 grid as an example."

"It is also a square composed of odd sides. Assuming that all lights are off, then if we consider using the next row to brighten all the previous row, then it is equivalent to clicking all the grids in the second row once, and then It's going to be like this."

Luo Hao took a piece of paper and drew on it: "Suppose 0 means light off and 1 means light on. Then after clicking the second line, the top two lines will look like this."

111

010

Huang Xi looked at the pattern drawn on the paper and nodded.

"At this time, we have clicked three times. If we want the second row to become 1, then the third row needs to be clicked at least twice. This is 2 times, not to mention that the final result of the third row is not necessarily the same. It will be full light."

"If we change our thinking and click on the lights on the four corners first, then after clicking four times, the result will be like this." Luo Hao picked up the pen and started drawing again.

101

000

101

"What did you see?" Luo Hao asked Huang Xi with a smile.

"Hey, in that case. Click the middle square again to light up all of them." Huang Xi was a little surprised, "This is 5 clicks, which will be less than the previous method."

"Well, although this question is different from the example I gave during the competition, it won't be much different." Luo Hao said, "Sometimes inertial thinking can hurt people, especially when you see someone using After this method is successful, the inertial thinking in your heart will affect you subconsciously, making you unable to escape this frame and losing the ability to innovate.”

"So, sometimes, you have to think more and try more. Only then can you be innovative." Luo Hao said with a smile.

Luo Mu on the side has not spoken, but there is a hint of relief in her eyes.

On the TV, Zhang Yi had already completed the answer, but it took 6 minutes and 21 seconds.

Zhang Yi's first reaction after finishing was to look at Luo Hao.In the end, he was surprised to find that Luo Hao was looking around leisurely.Zhang Yi frowned, glanced at the results on the big screen, and was taken aback for a moment.However, he reacted immediately, his face softened a little, the key to deciding whether to win in the end lies in the number of operations.

Zhang Yuqing looked at Zhang Yi, nodded slightly, and said, "Okay, both contestants have completed their own solutions. The big screen also shows the time for their solutions. But the most critical number of operations, It hasn't shown up yet."

"In this second competition, which contestant can win?" Zhang Yuqing looked at the audience in the audience, "Why don't our audience guess it? Pick up the voting machine next to our seats and think that Zhang Yi can win." If you win, press 1; if you think Luo Hao can win, press 2. If you guess correctly, you will get a small prize carefully prepared by our program team!"

"I don't know who came up with this idea. When I was sitting there, I could feel that the high momentum of Zhang Yi next to me was beaten down."

In the living room, Luo Hao complained.

The results of the vote will be out soon.

Undoubtedly, Luo Hao had more votes than Zhang Yi. After all, Luo Hao's time was shorter, and it is likely that the number of operations was less.
