2019, the first day of the new year.

Li Zheng has been working hard all day to become a real veteran programmer.

There is still half a year to go before the information competition, and it stands to reason that this should not be done so early.

But the upgrade of the software is imminent.

The district-wide joint examination will be held at the end of January, even if Li Zheng doesn't need this software, Teacher Mengxi and the dog apprentice Zhang Xiaoke also need it.

They have already finished the special question bank they gave before, and now it is the time for the second round to check and fill in the gaps and challenge the rankings.

To this end, Li Zheng did not hesitate to spend about 20 minutes to study the basic algorithms, data structures and databases.

After that, it took about ten minutes to rewrite version 0.1 of the demon cultivation system with the idea of C++.

Also known as, personalized dynamic question bank version.

If there are no bugs, you only need to enter the results of the previous brushing questions, and the system can re-evaluate the level of each subject and each knowledge point of the user, and give a second round of question banks.

What is stupid is that at this stage, you can only manually enter the results of brushing questions, and then manually select the topic.

In order to really achieve efficient learning feedback, on the one hand, a huge question bank is needed, and on the other hand, it is also necessary to develop a "question recognition" or "online brushing" function, so that AI can judge and write the results, and then select targeted questions from the total question bank to achieve output according to the results.

This is not only a problem of programming, but also involves a large amount of data and algorithms, which is far from being solved by Li Zheng at this stage.

All he can do is to manually enter the selected topics into the database, and code and group them according to their difficulty and corresponding knowledge points, although the efficiency is extremely low and a drop in the bucket, but it is finally the first step.

Also, if this personalized learning system can really be realized......

The teacher of the after-school tutoring class is afraid that he will be unemployed.

Isn't it okay, in front of the title, there is also a tutorial class terminator?

......

January 2nd, the first day of the new year, the day before the start of the physical competition improvement class.

The first thing Li Zheng did when he entered the school was to "explain the future".

In the first class of the third year of high school, everyone was not surprised by Li Zheng's arrival.

Xu Mengxi also accepted the reality and completely gave up the idea of bombarding him to go out and talk.

Li Zheng held a piece of paper in his left hand and a few catties of questions in his right hand, walked to the table in one step and presented the paper.

"Teacher Mengxi, this is your data change, and the progress is obvious. ”

"Ah......" Xu Mengxi looked at the data sheet, his chin slowly lengthened, and in addition to shock, there was more doubt.

[Mathematics: 66→73]

【Exponential Functions and Power Operations: Good-→Excellent-】

【Relationship and Calculation of Convex Polyhedra: Difference →+】

......

[Physics: 78→82]

[Power in closed circuit: Medium → good-]

"This ...... This...... Is this really calculated by software?" Xu Mengxi was a little unbearable, but still bit his lip and said, "It's all your own little by little calculation, right?"

Li Zheng frowned, very dissatisfied: "What are you kidding, you are insulting an old programmer, I am just responsible for typing and printing." ”

"I ...... I don't believe ......"

"Just go back and compile a stable version of Windows and send you a copy. Li Zheng said, carrying the plastic rope in his right hand.

Boom!

The eight-pound exercise slammed on the table.

"These are the targeted questions that you have fed back based on your current situation, which should be enough for you to do the final exam. Li Zheng looked at the question half a meter high and said, "Don't forget to turn the book if you have difficulties, and you can ask me." ”

Xu Mengxi became more and more distressed.

It's almost time for the final exam, and I have to prepare for the physics competition.

Li Zheng spent so much energy on me......

Not to mention reciprocation, even words of gratitude are not enough.

"Please...... Don't do that again...... Oh, I don't even know what to say......" Xu Mengxi was so anxious that he made a mess, suddenly remembered something, turned around and flipped up his schoolbag, "By the way, the gold medal should also be returned to you......"

But she finally found the gold medal and raised her head again.

Li Zheng had already slid out of the classroom.

"!!!" Xu Mengxi was so angry that he punched the air on the spot, "It's like this every time, don't say hello, just throw it down and leave." ”

Behind her, Qiao Bixia was looking at her like an old mother, smiling kindly.

"Okay, according to my understanding of this kid, he is actually learning easily, didn't you say before that he was going to do all the five major competitions, and secretly complained that he was not single-minded......"

Xu Mengxi turned around and pressed it on Qiao Bixia's mouth as if he had eaten gunpowder: "Okay, don't say it!"

"Hahaha!" Although Qiao Bixia was pressed, she could laugh, "I can't think of it-my mouth is bigger than your hand, I just said that he is not single-minded in learning, what are you excited about." ”

"What?" someone in the front row looked back in surprise, "Li Zheng is not single-minded?"

Another person: "Li Zheng's heart?"

"Li Zheng pedals on two boats?"

"Li Zheng scumbag?"

"Li Zheng is too much!"

At this moment, Xu Mengxi deeply realized what it means to be quiet and the wind does not stop.

......

The fourth class of the second year of high school also staged a similar scene.

It's just that the taste is a little heavier.

After all, it's Zhang Xiaoke, it's not so easy to feed.

"12 pounds, it's not enough to say more. Li Zheng stacked the exercises next to Zhang Xiaoke's desk, and said, "Mathematics, physics and chemistry have improved by more than 30 in total, and they are worthy of being my apprentices." ”

Looking at this big question, even Zhang Xiaoke swallowed and foamed.

"Master, the paper money alone is worth several hundred, right?"

"Don't think about this, learn from me, the question is enough. Li Zheng said, clapped his hands, and sat down at the table, "Chong Jingbei, the question must be done on catties." ”

"Our teacher, the taste is heavy......" Zhang Xiaoke stroked the heavy question dam, looked at his report card and sighed, "Since it's all like this, there's no need to say thank you, I'll do it, I'll do it all." ”

"Ambitious. Li Zheng's heart moved, and he couldn't stop laughing, "In the final district-wide joint examination, if you don't know your original classmates, you can also see your ranking, and it's time for you to be a person." ”

“！！！”

Li Zheng laughed and said: "When the time comes, you will generously say to the classmates who have been surpassed by you, just work hard and be strong." ”

"Master......" Zhang Xiaoke looked at Li Zheng with tears in his eyes, "How should I repay you?" or ...... I've danced. ”

"Who wants to see this. ”

"Huh?"

A familiar voice came, and Lin Yujing stopped behind the two of them with a kettle: "I want to see the split." ”

"I won't give you a split. Zhang Xiaoke's eyebrows narrowed, and he looked back vigilantly, "From now on, I am completely on the same page as Master, you have to be careful." ”

"Huh~" Lin Yujing turned around and turned to his seat, "Your master has fallen into the training class." ”

"It's an improvement class. Li Zheng scolded from afar, "It's your loss if you don't go, just wait, we will be people of two worlds in a week." ”

"Huh. Lin Yujing turned her head and sneered contemptuously, "When have you ever been to a world?"

"Dry. Li Zheng was so angry that he slammed the table.

Truly...... I have never been to a level......

But this time is really different, and there is no way to fail the physics competition.

Damn, why wait until April......

It's been too long to bear.

It's good to use the final exam as a killer.

As he was talking, Liu Xin rushed into the classroom, and ran to Li Zheng's side without putting his schoolbag and showed his mobile phone: "There is a force to send the performance video to the bar, Brother Li, you want to be famous!"

Li Zheng's eyebrows tightened and he looked at the screen.

[City No. 1 School X Sakura Lake Middle School X New Year's Eve Performance Surprises All Musical Instruments Proficient Boss]

At this time, it was the part where the Conan saxophone was played, the clarity was very low, and the shaking was serious, and it seemed to be taken with a mobile phone.

The barrage also floated out one by one.

[Now middle school students are so powerful?]

【Is Sakurako a conservatory?】

[This person is also the champion of the national chemistry competition......]

[I can't see the girl clearly!Is there a clear version?]

[Haha, Li Zheng from our school is a real big guy!]

Looking further down, although the video has only a few thousand views, there are a lot of comments, and many people from Ichichi and Sakurako have commented to introduce the background.

Looking at it, a red-faced Jiang Qinghua came over and reminded him kindly: "It's almost class, it's almost over." ”

Everyone is a little unfamiliar with this positive tone and energetic timbre.

But when he turned his head to look, it was indeed Jiang Qinghua.

"Oops!" Zhang Xiaoke exclaimed, "It's the sour smell of love." ”

"Ahh ”

"Mom!" Zhang Xiaoke hugged his head and said, "After fighting for so long, I actually let you get rid of the order first." ”

"What's going on?!" Liu Xin was so shocked that he put away his mobile phone and sat back in his seat, "Who? ”

Jiang Qinghua only smiled and waved his hand: "Ring the preparatory bell, let's talk about it later." ”

Li Zheng saw that the wood was already in the boat, and it was difficult to persuade him to study anymore.

After all, Du Shitong is from a school in the city, and his grades will not be too bad.

Associating with such a person does not necessarily affect Jiang Qinghua's learning.

But in case, it was the existence of Zhang Xiaoke before, it would be difficult to say.

After all, Jiang Qinghua is his own person, and Li Zheng still subconsciously helps him plan to get up.

"How's she studying?"

"Didn't talk much...... It seems to be in the middle ranking...... Jiang Qinghua said hesitantly, "But the middle of the first school in the city is definitely much better than me." ”

Li Zheng couldn't help asking: "Specifically, is it better at Chinese or mathematics, and what competitions have you participated in?"

"What are you asking for......

"My dad always said that you have to be the right person, so I won't help you plan it. Li Zheng gestured, "Measure the results of each subject, and only if you are worthy of it can you continue to develop, if you have to be too poor, it will not be long before there will be many contradictions." ”

Jiang Qinghua swallowed and foamed: "No, Li Zheng...... That's not what it means. ”

"We're still middle school students, so that's pretty much what it means. Li Zheng clapped his palms, "When the time comes, people will take a 985 exam, and you won't even be 211, get along together, do you live in your own heart?"

“...... This one...... It's also ......" Jiang Qinghua's originally beaming face unconsciously sank again, covered with a faint layer of frost, "After all...... It's a city school...... Even if it's just in the middle of the stream...... 985 is not much of a problem...... I seem to ...... It's really not worthy of her......"

"Hey, hey......" Zhang Xiaoke couldn't look at it, and pulled Li Zheng's shoulder and said, "Master, you ...... You don't want to be like this, Qinghua was finally happy for two days...... You're too inhuman......"

"No, no, no. Jiang Qinghua grabbed his hair hard, "Li Zheng is thinking about me, I should really recognize myself ......"

"Don't be too pessimistic, God rewards hard work, and we have room to work hard. Li Zheng gently patted Jiang Qinghua's hand hanging on the table, "I have a demon learning system here, which can be open to testing for my own people, and intelligently solve questions, no matter how many people you are missing, if you make it a few dozen catties of papers, you can afford to climb high, do you want to try it?"

Jiang Qinghua's eyes lit up: "Oh? is it the one for Zhang Xiaoke and Xu Mengxi?"

Excited, he didn't see Zhang Xiaoke and Liu Xin shaking their heads wildly.

"Yes. Li Zheng replied.

"Can I too?" Jiang Qinghua asked again.

"Of course. ”

"Then count me as one. Jiang Qinghua nodded violently, and then suddenly became a little worried, "It's just...... What did you just say, catty?"

"Don't worry about these details. Li Zheng rubbed his hands and said, "Come to my house after school, bring all the papers you have done this semester, and I will ensure that you have a five-pound foundation." ”

"Can you ...... Don't say catty anymore, I'm scared ......"

Li Zheng smiled generously: "Eh, I'm not afraid to do it, I don't believe you can ask Xiao Ke." ”

"Ah...... This ......" Zhang Xiao could see that Jiang Qinghua was still involved, so he had to sigh, "People are different...... All I can say is, come on, work hard, please be strong. ”

......

That night, Jiang Qinghua came out of Li Zheng's house at half past ten.

Holding a USB flash drive worth five catties in his hand.

Wow.

The phone rings.

Jiang Qinghua looked down and smiled rarely.

[Poetry boy: After finishing your homework, go to sleep.] 】

[Jiang Qinghua: I haven't moved a word yet......]

[Shitong: Are you busy with the work of the squad leader? 】

[Jiang Qinghua: I mean, my day has just begun, and tonight is 100% going to be all-nighter. 】

[Shitong: Don't do this...... Staying up late is very inefficient, and ...... Your hairline is already quite a bit higher than your peers...... It is recommended that you take good care of it. 】

Jiang Qinghua rubbed her hair and suffocated for a while.

This...... That's starting to dislike me?

[Jiang Qinghua: But I ...... The school is too bad for you, if you don't work hard......]

[Shitong: Ah, what do you want to do with this? I'm not very good...... The current score is at most 985 in the middle and lower reaches......]

Jiang Qinghua was suffocated again.

985 is a goal that I dare not think of.

But at Du Shitong's.

That's it......

Nothing more......

Sure enough, the difference in learning has led to the difference in three views.

Faced with the same thing, opinions and visions will be very different.

At this time, I said that 985 was very powerful, and I didn't dare to think about it......

will only be despised, and then lose the common topic, and then separate because of the incompatibility of personalities......

Li Zheng is right again, it turns out that he really has the right door to study.

[Jiang Qinghua: It's okay, don't think about it, I just think it's possible, I want to try to be admitted to the same university as you. 】

[Poetry Child: (blushing) (blushing) (blushing)]

[Poet Boy: Is that possible to occasionally play in the ensemble at school (blushing)]

[Jiang Qinghua: Of course!]

[Shitong: I understand, then come on! Sleep for at least two or three hours. 】

[Jiang Qinghua: Obey!]

[Shitong: We will also work hard for the final joint examination, and we can almost launch the college entrance examination ranking according to the ranking of the whole district, and then discuss the school...... (blushing)】

[Jiang Qinghua: Very good!]

Li Zheng's statement was fulfilled again.

Looking at the academic performance, the meaning of the poem fairy tale is obvious.

If her academic performance is not at the same level as her......

There can simply be no future!

In the dark night, Jiang Qinghua glared at the bicycle with all his might, and his long hair fluttered.

I see, Li Zheng.

Learning is all about it.

What is a hairline?
