Turing Forbidden Zone

10 minute later.

There was a lively queue in the cafeteria, which happened to be the time when the students finished their classes on weekdays.

Shi Ye walked around with the tray for a while, sat down in his usual corner, and waited to eat his dinner quietly.

However, not long after, when the freshmen finished their military training, another large group of people flooded into the cafeteria.

Yan Kairui and Wang Gu were among them, they searched for a long time with their dinner, and were pleasantly surprised to see Shi Ye.

The two sat down opposite him without saying a word, and Yan Kairui warmly greeted him: "Brother Ye, what a coincidence! You didn't come to the military training today?"

Shi Ye remained silent and continued with his actions.

Regarding Shi Ye's reaction, Yan Kairui accepted it very well, and even said skillfully: "I don't want to talk to anyone today, Brother Ye, then I won't bother you."

After speaking, he turned his head and chatted with Wang Gu.

Wang Gu was a little more cautious, secretly observed Shi Ye for several times, and then entered the topic.

Halfway through eating, a girl jogged over, blushing, and pretended to be generous and said: "Hey, some handsome guys. I accidentally bought an extra fried chicken nugget. I can't finish it anyway, so why not share it with everyone?" Alright."

After finishing speaking, a golden and attractive fried chicken nugget was placed on their table.

After a while, she saw that Shi Ye didn't respond, and quietly reached out and pushed it towards Shi Ye.

Shi Ye was expressionless.

Yan Kairui: "..."

Wang Gu: "..."

After the girl left, two more people came one after another. Among them was a shy boy who came over and said, "Let's make friends!"

So soon there was another fish, a serving of jelly, a small cake, and three boxes of yogurt on their table.

Attached with it were three small notes with contact information and two club recruiting posters.

Shi Ye remained expressionless.

Yan Kairui has already gasped: "Hiss, is this the treatment of a handsome guy? Brother Ye is really terrifying."

After all, he stretched out his hand and took a box of yogurt, happily plugged in the straw and enjoyed it.

"..." Wang Gu hesitated for a moment, and took his own share.

If there is too much food, there will be annoyance that you can't finish it, and the topics at the dinner table will be prolonged accordingly.

Afterwards, Yan Kairui raised his belly, danced, and said to Wang Gu: "...just the Golden Lotus Cup, the first question of the complete backpack, it's easy to understand, that is, there are N things to put in the backpack, and the weight is random , the value is also random, and we need to find a way to put the most valuable things in. The most convenient way to do this problem is the greedy algorithm, but the efficiency is very low; so we also have recursive methods and dynamic programming methods.”

Wang Gu, who was forced to sign up for the Golden Lotus Cup, looked like he was studying hard, and took out his small notebook to take notes.

Seeing that he was listening so intently, Yan Kairui couldn't help but feel radiant on his face, so he continued: "...For example, the most important thing about this dynamic programming method is to find the state transition equation, which can be extended according to the solution of the 01 knapsack problem. For example Say I just saw on the Internet that the i-th thing can be disassembled into something with a weight of w*2^k and a value of v*2^k, and the dimensionality is reduced to the point of binary, and the time complexity is only... um... only……"

As he spoke, his eyes were empty, and he couldn't recall the strategy he saw before.

After scratching his ears and cheeks for a long time, Yan Kairui looked at Wang Gu's bewildered expression, and decided to fool him: "It's, it's probably logN."

Time and night: "..."

At this moment, Shi Ye turned on the phone silently, and typed a line on the notepad:

【O(W∑logNi)】

Then he put the phone on the table and turned it 180 degrees so that the two people on the opposite side could see it.

"Ah! That's right, it's this complexity!" Yan Kairui suddenly realized, and then looked up in horror, "Wow, Brother Ye!!!"

Wang Gu also raised his head in surprise: "Brother Ye, can you hear us talking?"

Yan Kairui pinched Wang Gu's hand and said, "Wow, am I dreaming? Brother Ye will help us solve the problem! Oh my god, it means that I was lucky by Brother Ye?"

But then they saw that Shi Ye took the phone back and put the bowl back on the plate.

Yan Kairui: "Brother Ye, is your meal ready?"

Shi Ye: "..." Silently wiped the table with a tissue.

Yan Kairui: "Brother Ye, are you going back to the dormitory? Let's go to the library and learn the complete knapsack problem."

Shi Ye: "..." silently picked up the plate and stood up.

Yan Kairui: "Brother Ye, do you want something for dinner? I can bring it."

Shi Ye: "..." silently turned around and walked away.

Yan Kairui sighed with infinite disappointment: "Ah..."

Wang Gu: "Brother Ye didn't eat a single bite of so many things."

Yan Kairui cheered up again and said, "Yeah! Then these are all ours!"

None of the three noticed that while they were having dinner, someone in the noisy cafeteria was secretly observing them.

Wen Bai: "Brother Zong, look at that kid... talking and laughing with others."

Chu Ying folded her arms around her chest, crossed her legs, and showed "I'm very upset" all over her face, and didn't touch the rich food on the table.

"Oh, another tender primary school girl has passed by! Isn't this kid just a little taller, cut."

"Oh, he didn't refuse when he was invited to dinner."

Snapped.

Chu Ying patted the table and said coldly: "Eating your food, what do you want to see? They just don't like my treats, but they are willing to eat other people's food, and they haven't violated the law, huh."

The two looked at his expression and immediately chose to shut up.

Wen Bai thought in his heart: It's not good, Brother Zong is now worth 80% for being unhappy, and 50% for being wronged, don't mess with him, don't mess with him.

After a bad dinner, Chu Yingzong continued to walk around the playground with a dirty face.

Not long after, he happened to see Shi Ye, who was leaving the library, as if he had just borrowed two books and was about to go back to the dormitory.

At this time, the sky will be dark, and the setting sun will shine red light on Shi Ye's face, stretching his shadow very long.

It was clear that the crowd was bustling, but he still seemed like an isolated island.

Chu Yingzong quietly followed behind Shi Ye, thinking: I'll just see which dormitory this kid is in, so that I can find opportunities to retaliate later, hum!

However, after walking for a while, he found that Shi Ye was stopped by someone.

——It’s the psychology teacher.

Seeing Shi Ye at first glance, the psychology teacher was also a little surprised, and said, "Hey, classmate, wait a minute! I finally found you. You don't seem to be registered on the list this afternoon. I can't contact you."

Being blocked by her, Shi Ye paused slightly.

The psychology teacher took out a business card and said, "I didn't have time to thank you this afternoon. Thanks to your reminder, I found out that my mobile phone had a Trojan horse, and I quickly sent it to a mobile phone shop for repair. I can't add you as a friend now. My surname is Xu, this is my contact information—you can add me, and you can find me anytime in the counseling room.”

Shi Ye's eyes rested on the business card for a moment, and realized that this was the purpose of her blocking the way, so he stretched out his hand to take it.

The psychology teacher smiled when he saw this.

Seeing the woman's smiling face from a distance, the corners of Chu Yingzong's mouth completely twitched.

He kicked away the stones on the side of the road and snorted coldly.

——Any pretty woman can treat him to snacks and exchange contact information?shallow! !

After a while, the psychology teacher left briskly.

The sky also darkened quickly, and there were fewer and fewer pedestrians around, and they all hurried back to the dormitory.

Shiye continued walking in the shade of the trees, and then saw a long and narrow shadow in front of him.

Chu Ying put her hands in her trouser pockets, stared at him angrily, and said, "Hey, it's a waste of time for the senior to invite you to dinner? You can't wait for the pretty senior to invite you to dinner?"

At this time, Shi Ye had only one thought in his mind: Why did he come to block my way again?

Shi Ye asked, "What else do you want?"

The corners of Chu Yingzong's eyes twitched slightly: "What do you mean by that, you treat me like a foolish kid?"

Shi Ye: "Yeah."

Chu Yingzong: "..." Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!

What kind of ability does this person have, why can one syllable make him so angry that he wants to explode!

Chu Ying stared at him, and said viciously: "Smelly, smelly junior! I'm going to waste your time today! You just stand here for me, and you are not allowed to leave until it is dark!"

Shi Ye looked at the horizon and said calmly, "It's getting dark."

Chu Ying didn't even think about it and said, "It doesn't count if the lights haven't turned on yet! You won't be allowed to leave until all the lights in this building are turned on!"

Shi Ye looked at the building he was pointing at, which was the old building where the psychological counseling room was located.

Shi Ye stood where he was, took out his phone and looked at it.

Chu Ying Zong said: "Hey, you are not looking for a teacher to give a small report, are you?"

Shi Ye: "No."

Seeing him bowing his head and calmly in the night, Chu Ying calmed down unconsciously, and even inexplicably said with a little joy: "Do you know how to respect the senior? Be good, the senior will bring you a cold drink for the military training tomorrow."

Shi Ye: "Oh."

Chu Ying raised the corner of her mouth, and said again: "Hey, what are you doing in a daze? Move over your phone and add me as a friend."

He just leaned over to look at Shi Ye's phone, but saw that the screen went off very quickly.

Shi Ye locked the phone screen, silently raised his head and looked at Chu Yingzong.

At this moment, Chu Yingzong only heard a few crackles, a very slight sound resounding in the night.

Then he sees:

There was light gushing out from behind Shiye.

The flawless brilliance instantly illuminated his eyes as brightly as day, and also blurred his figure into a halo.

Shi Ye said flatly, "The light is on."

As his voice fell, Chu Yingzong's eyes got used to the sudden light, and then he saw the old building in front of him start to light up from the ground floor, and it was brightly lit in a blink of an eye.

Then the light spread to teaching buildings, dormitory buildings, laboratory buildings... until the entire campus was lit up.

Then, the street lights gradually lit up from above their heads, extending to the end of the road, connecting the entire distant night scene.

The whole world seemed to wake up at an order.

The galaxy is gorgeous and the city of lights is brilliant. This summer night has never been so bright.

When Chu Yingzong suddenly turned around again, she realized that Shi Ye had already left.

The lonely shadow of this person walked past the street lamps and the light from the window, turned his back to the light of the world, turned into the empty alley, and quietly disappeared into the darkness.
