"Alright, when you make it, come here."

Du Rufang waved his hand and spoke.

Leng Tanxuan's face turned blue, this is too insulting!

The other party didn't take him seriously at all, otherwise he wouldn't have taken a question out, as if he was testing him.

"How can this question be answered in such a short period of time?"

He felt that the other party was deliberately embarrassing himself, so he did it.

When Du Rufang heard this, he looked at Lu Chensheng and the two on the side, "Then you ask how long it will take for the two of them to answer?" ”

Yu Feihan smiled slightly when he heard this, "It only takes a cup of tea." ”

"What about you?"

After listening to this, Du Rufang turned his head and glanced at Lu Chensheng on the side.

Lu Chensheng was speechless, poured himself a glass of wine, and slowly took a sip, "I have already answered." ”

Well?

Lu Chensheng's words fell, and several people on the side turned their heads to look at them, even Du Rufang also turned their heads to look at Lu Chensheng.

"I'm afraid you've already done this before!"

Leng Tanxuan looked at Lu Chensheng, his eyes were full of suspicion.

Lu Chensheng smiled dumbly, "Why, can't I see anyone better than you?" ”

"That's not it," Leng Tanxuan sneered, "It's the champion of our Chengzhou Kingdom, it all takes a cup of tea, how can you calculate it in such a short time?" This is not done, and what can be explained? ”

Lu Chensheng shook his head, "Okay, let's teach you." ”

As he spoke, Lu Chensheng took the paper in the other party's hand, which said 1+2+3+4+5...+100.

"For this kind of arithmetic problem, you only need to add the beginning and the end, and multiply the mantissa by the value of 2, so the answer to this question is five thousand and fifty."

Lu Chensheng just wrote slightly, and then he calculated the answer, and several people on the side were stunned.

"That's, you're unheard of!"

Leng Tanxuan was stunned, and then said angrily.

He's not a fool, he's never heard anyone mention such an algorithm, even those scholars!

Yu Feihan on the side also frowned at this time, looking at Lu Chensheng, his eyes full of puzzlement.

He really hadn't heard of such an algorithm.

Some scholars on the side also leaned over, scratched their heads at the topic in front of them, and looked at Lu Chensheng's algorithm, and scratched their heads even more.

"That's right."

Yu Feihan was silent for a while, and then said, "It's just that I haven't heard of this algorithm." ”

Du Rufang also nodded at this time, "The answer is indeed right. ”

Listening to the two of them admitting that the answer was right, Leng Tanxuan sneered even more on the side.

"How, you don't understand how you calculated this question at all, but you have calculated it before, so you just fabricated this answer at will!"

was just looking at Lu Chensheng's impatience, and when Leng Tanxuan spoke at this time, he was even more unkind.

Lu Chensheng raised his head and looked at the scholar in front of him, a little like he was looking at an idiot, "With such an IQ as you, it's hard for me to tell you what this algorithm is all about." ”

"You!"

Lu Chensheng's swaying ridicule made Leng Tanxuan suddenly angry, pointing at Lu Chensheng's trembling body, and he didn't know what to say for a while.

Du Rufang had just expressed his disdain for him, and now there was another Lu Chensheng, how could he not be angry?

"That's it, it's a different kind of life that makes you live quietly, maybe you'll understand a little."

Lu Chensheng shook his head, as if he was a little helpless, and took a piece of paper as if he was teaching children.

This kind of arithmetic is actually very interesting, and if you look closely, you can see that one plus ninety-nine is one hundred, two plus ninety-eight is also one hundred, and three plus ninety-seven is also one hundred.

So we can get that there are forty-nine hundreds, and the other is the remaining fifty and one hundred, so isn't it fifty one hundred and one fifty? Isn't the answer so out? ”

When everyone heard this, they suddenly came to their senses, and some of them didn't understand it, but they also understood it after watching it a few more times, and then they clapped their hands one after another.

"I didn't expect that this problem could be solved like this!"

"What I learned before might as well be Lu Gongzi's awakening."

Du Rufang on the side also nodded at this moment, "Brother Lu is smart, and he actually figured out such an algorithm." ”

Several people praised it again and again, and they already felt that Lu Chensheng's ability to learn was not weak.

Seeing this scene, Leng Tanxuan's face changed slightly, he never thought that this question would be so simple.

Thinking about it this way, it seems that Lu Chensheng can indeed calculate this problem in a very short time? Is this the gap between him and Lu Chensheng and others?

Leng Tanxuan's face changed for a moment, and he was still a little unconvinced.

"And what's going on with that algorithm you just had? This is clearly an unheard of algorithm! ”

Lu Chensheng was speechless, why is this guy still struggling with this algorithm?

"I'm not wrong with this algorithm, but I don't think it's easy to explain it with your IQ, if you question it, you can just apply it yourself and try it, but you can lower the number.

For example, if you add one to nine, multiply the value of one plus nine by nine by two, and see if the answer is correct. ”

Lu Chensheng was still drinking slowly, but he didn't pay any attention to the meaning of this cold talk.

When Du Rufang heard this, he suddenly came to his senses.

The same is Yu Feihan, both of them took the blank paper and began to calculate, and after a while, both of them suddenly raised their heads.

"How is that possible! Why are all the values correct? I've got all three sets of values right! ”

"I've calculated five sets of values, and they're all right!"

The two of them went one after the other, and it was Du Rufang who counted five groups.

At the same time, it can be seen that Du Rufang is still a step higher, which makes Yu Feihan's face on the side change slightly.

But then he came back to his senses, and what shocked him deeply was, why are these numerical calculations correct? Could it be that the algorithm given by Lu Chensheng can really solve all such similar problems?

Hearing this, Lu Chensheng looked at the two people in front of him, and after being silent for a while, he said, "With your..."

"Okay, brother, don't talk about it, I'll understand."

As soon as Lu Chensheng spoke, Yu Feihan immediately raised his hand and signaled Lu Chensheng to stop talking.

He felt that Lu Chensheng's words were really too hurtful.

Du Rufang didn't care at all, because he knew earlier that Lu Chensheng's arrogance was not even comparable to him, and he had never understood it very well before, but now this question has given him a glimpse of the tip of the iceberg.
