Data structure, programming, algorithm processing......

Dynamic Programming, Breadth First, Greed, Binary Tree......

In the examination room of the NOIP semi-finals, Xu Zhe finally experienced the feeling of scratching his ears and cheeks. It's completely different from the junior high school exam, and the more you go on, the more difficult it is to do well. Facing the computer-based computer, he took it seriously and did his best......

Finally, the exam is over.

Xu Zhe walked out of the unfamiliar teaching building and walked straight outside. Suddenly, he was tapped on the shoulder.

Looking back, it was Shen Lan.

The senior sister smiled and asked, "How do you feel?" ”

Xu Zhe smiled wryly: "It's still difficult, and I don't know what the result will be." ”

Shen Lan nodded: "Yes, this difficulty must not be low, otherwise how can you distinguish different levels?" But I still have faith in you. Saving one is certainly not a problem. ”

Xu Zhe waved his hand: "Don't, it's better not to set a flag for me, I don't know what the result will be." ”

Shen Lan: "What does it mean to set up a FLAG?" ”

Xu Zhe: "It's just planting the flag, do you imagine what happens to the people who say 'go back to their hometown to get married after this battle' in the movie?" ”

Shen Lan tilted her head: "Back to your hometown?" ”

Xu Zhe realized that the senior sister in front of him might not watch much film and television dramas, so he explained: "That's the real hometown, back to the road of reincarnation." Before the water is revealed, the kind of person who swears to say what kind of person he wants is to set up a flag for himself. ”

Before the words fell, Shen Lan was a little stunned, and she didn't know what she had in mind......

When the two walked to the school gate, they saw Song Xingye and Tang Lingfei, who had been waiting here for a long time. The two girls were chatting, and when they saw Xu Zhe coming, they hurriedly waved their arms to say hello.

Of course, it was Tang Lingfei who waved his arm, and Song Xingye waved his hand restrainedly.

At this time, it was not yet four o'clock in the afternoon, and there was still some time before dinner, so Shen Lan naturally proposed, "Do you want to go to the nearby park?" I've been busy with the computer for so long, Xu Zhe, you also want to breathe, right? ”

Shen Lan had already memorized that word at this time, although she didn't know where Xu Zhe heard it, but she couldn't help but think of the feeling of complacency when she stepped on a spot to inspect a nearby park not long ago.

It's like setting a flag.

The development so far has really been a bit beyond her expectations. These two little girls actually came with Xu Zhe, which seemed to add a lot of distractions to her plan.

Plans can still be continued.

It's just that Shen Lan no longer wants to say things like 'I don't even know how to lose'.

After walking for a while, Shen Lan finally took the three juniors to the go-kart track.

Then he pretended to be the first time he found it: "Eh, there's a go-kart here, why don't you try it?" Xu Zhe, do you dare to compare ...... with me?"

Before Shen Lan's words were finished, he couldn't help but pause. Because she found that Xu Zhe's face was a little wrong.

He took a step back: "Let's play, I'm not interested in this." ”

Shen Lan: "Not interested? ”

"Well, among all the games, the only one I don't know how to play is a racing game."

Xu Zhe: This is the truth. In his last life, as a senior dead house, he played every major type of game, even including changing girls' clothes. But as soon as he saw a racing game, he couldn't help but think of the feeling of tumbling down a hill in a bus......

The psychological shadow of this life is not so strong, but he still doesn't want to touch the steering wheel at all. Anyway, you can take a taxi now, and you can directly hire a driver in the future, so why embarrass yourself in indifferent things?

However, Tang Lingfei raised his arm: "Karting, I'm interested!" ”

Although she was in that car back then, she has no memory of the accident. She only knew that the driver was sick with his heart, and Xu Zhe saved everyone in time. For her, there is no psychological shadow.

But Shen Lan was dumbfounded.

If you want to play racing with Xu Zhe and deliberately lose, who would want to play with a little rival!

But at this time, Song Xingye asked, "What's wrong with Senior Sister?" Don't you want to play go-karts? ”

"Oh, yes, come with me."

Shen Lan could only say this, then turned around and gritted his teeth secretly, and walked towards the entrance.

Xu Zhe and Song Xingye stood outside the runway and watched.

And Shen Lan and Tang Lingfei bought tickets to enter, each got into a car, fastened their seat belts and put on helmets with the help of the staff, and the car started and started.

The two started almost at the same time, but Shen Lan's car was further ahead. So, it was the senior sister in front, and Tang Lingfei was chasing behind.

At first, both of them were very unskilled in operation, and almost every turn had to hit the wall. But after running a lap, Tang Lingfei quickly mastered the trick.

Slow down when entering the corner, choose a good route, and then step on the accelerator after exiting the corner...... She's still a little rusty, but she's already in shape.

Song Xingye suddenly commented: "Fei Fei seems to be very good at driving." ”

Xu Zhe: "Her cerebellum is quite developed. ”

Song Xingye turned his head to look at him, and couldn't help but smile: "You mean, her brain is not developed?" ”

Xu Zhe shrugged: "I didn't say that, this is what you said." ”

At this moment, Tang Lingfei saw the right time, stabilized in a continuous curve and did not hit the wall, and when he accelerated out of the corner, he overtook Shen Lan's car.

Song Xingye couldn't help but applaud.

Xu Zhe: "This kid may be able to be a driver in the future." ”

However, Song Xingye said: "The driver is not driving a racing car, he must drive steadily." I think it's good to be a part-time maid driver. ”

Xu Zhe turned his head to look at her, and wanted to say, 'Don't talk about any maids', but looking at the girl's smart and serious gaze, he was a little speechless.

A single ticket entry is limited to two laps. As soon as the two laps arrived, the staff waved flags to signal them to stop.

Tang Lingfei was of course the first to cross the line. She jumped out of the go-kart, ran to Zhuma and her best friend, and couldn't help laughing: "This is really fun!" Don't you try? ”

Xu Zhe and Song Xingye shook their heads in unison.

Shen Lan walked over with slightly heavy steps. According to the original plan, she should now pretend to be dizzy and fall into Xu Zhe's arms. But just now, she was obviously serious, but she still lost to Tang Lingfei, which made her completely lose her mind to pretend to be pitiful.

Seeing that the atmosphere of the girls was a little delicate, Xu Zhe took the initiative to say, "Is there a delicious restaurant near here?" I'm in for a treat tonight! ”

Tang Lingfei cheered: "The boss is mighty! ”

Xu Zhe: "I'm not your boss......"

Shen Lan sighed and said, "Come with me." ”

The planned dinner location was still the one, but by now, the plan had changed beyond recognition.

And Shen Lan could only secretly review and summarize, thinking about how he lost.
