Chapter 202 (1/2)
2019, the first day of the new year.
Li Zheng has been working hard all day to become a real old programmer.
There is still half a year to go before the information competition. It should not have been started so early.
But the upgrade of learning magic software is imminent.
At the end of January, there will be a regional joint examination. Even if Li Zheng doesn't need this software, Mengxi teacher and dog apprentice Zhang Xiaoke also need it.
They have already finished the special question bank before, and now it is time for the second round to make up for deficiencies and challenge the ranking.
Therefore, Li Zheng did not hesitate to spend more than 20 minutes on the basic algorithm, data structure and database.
After that, it took about ten minutes to rewrite the 0.1 version of learning magic cultivation system with the idea of C + +.
Also known as personalized dynamic question bank version.
If there is no bug, you just need to input the results of the previous brush questions, then the magic learning system can re evaluate the level of each subject and knowledge point of users, and give the second round of question bank.
More stupid is, at this stage can only manually input the results of the brush, and then manually select the topic.
In order to really achieve high-efficiency learning feedback, on the one hand, it needs a huge question bank, on the other hand, it also needs to develop the function of ”identifying questions” or ”online brushing questions”, so that AI can judge and write the results, and then select the targeted questions from the total question bank to achieve output according to the results.
This is not only a programming problem, but also involves a lot of data and algorithms, which is far from what Li Zheng can solve at this stage.
What he can do is to manually input 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, it is only a drop in the bucket, but it is the first step.
In addition, if this kind of personalized learning system can be realized
The teachers in the extracurricular tutoring class are afraid to lose their jobs.
Maybe we need a tutor class terminator in front of the title?
……
January 2, the first day of the new year, the day before the opening of the physical competition improvement class.
The first thing Li Zheng did when he entered the school was to ”account for the future”.
In the first class of senior high school, people are not surprised by Li Zheng's arrival.
Xu Mengxi also accepted the reality and completely gave up the idea of blowing him out to speak.
Li Zheng held a piece of paper in his left hand and several jin questions in his right hand. He walked to the table step by step and presented the paper.
”Teacher Mengxi, this is your data change, the progress is obvious.”
”Ah...” Xu Mengxi looked at the data table, chin slowly elongated, astonished, more skeptical.
[Mathematics: 66 → 73]
[exponential function and power operation: good - → excellent -]
[relationship and calculation between convex polyhedrons: difference → medium +]
[physics: 78 → 82]
[power in closed circuit: medium → good -]
”this This Is this really a software calculation? ” Xu Mengxi could not bear it, but still bit his lips and said, ”is it all your own little calculation?”
Li Zheng frowned and was not satisfied: ”are you kidding? You are insulting an old programmer. I'm just responsible for inputting and printing.”
”I I don't believe it... ”
”Go back and compile a stable version of windows and send it to you.” Li Zheng said, holding a plastic rope in his right hand.
Bang!
Eight Jin exercises hit the table.
”These are the targeted questions that are fed back according to your current situation. They should be enough for your final exam.” Li Zheng looked at the title of half a meter high and said, ”if you have difficulties, don't forget to open the book. You can ask me.”
Xu Mengxi felt more and more distressed.
It's going to be the final exam. I have to prepare for the physics contest.
Li Zheng has spent so much energy on me
Don't give me back. I can't even thank you enough.
”Please Don't do this again Oh, I don't know what to say... ” Xu Mengxi was so anxious that he suddenly thought of something and turned over his schoolbag. ”By the way, the gold medal should be returned to you...”
But she finally found the gold medal, and then raised her head.
Li Zheng has already slipped out of the classroom.
“！！” Xu Mengxi was so angry that he beat up the air with his fist. ”It's always like this every time. You don't say hello, just leave.”
Behind her, Qiao Bixia was looking at her like an old mother, smiling with kindness.
”Well, according to my understanding of this boy, he is actually learning freely. Didn't you say that he prepared to do all the five major competitions, and secretly complained that he was not single-minded...”
Like eating gunpowder, Xu Mengxi turned and pressed it on Qiao Bixia's mouth: ”OK, don't say it!”
”Ha ha ha ha!” Although Qiao Bixia was pressed, she could also laugh out, ”I can't believe it - you are bigger than your hand. I just said that he is not single-minded in his study. What are you excited about?””What?” Someone in the front row was surprised and turned back, ”Li Zheng is not single-minded?”
Another: ”Li Zheng flower heart?”
”Li Zheng's two boats?”
”Li zhengzha male?”
”Li Zheng is too much!”
At this moment, Xu Mengxi deeply realized that what is meant by trees to be quiet and the wind not only.
……
Class four, senior two, also staged a similar scene.
It's just that it's a bit heavier.
After all, it's Zhang Xiaoke. It's not so easy to feed.
”12 catties, not enough.” Li Zheng held the exercises stacked next to Zhang Xiaoke's desk and said, ”the total number of students in mathematics and chemistry has increased by more than 30, which is worthy of being my apprentice.”
Looking at this big lump topic, even if is Zhang Xiaoke also swallows the mouth to spit.
”Master, it will cost hundreds of paper money alone?”
”Don't think about it. Learn from me. You can manage the problems.” Li Zheng said, clapped his hands, back to the table and sat down, ”Chong Jingbei, the title must be done by Jin.”
”Our school has a strong taste...” Zhang Xiaoke stroked the massive dam 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 magic heart moved, laughing more than, ”the final district joint examination, you can not make the original students, you can also see your ranking, you are also time to be a person.”
“！！！”
Li Zheng laughs: ”when the time comes, you are magnanimous to say to the classmate that you surpass, come on, work hard and be strong.”
”Master...” Zhang Xiaoke looked at Li Zheng with tears, ”how should I repay you? Or Can I split you a fork? I've practiced dancing. ”
”Who wants to see this?”
”Well?”
Familiar voice came, Lin Yue Jing holding the kettle stopped behind two people: ”to see the split.”
”I won't chop you.” Zhang Xiaoke frowned and looked back warily. ”Now, I'm totally with master. You should be careful.”
”Bang ~” Lin yuejing turned to his seat. ”Your master has fallen to the training class.”
”It's an improvement class.” Li Zheng scolded from afar, ”it's your loss if you don't go. We'll be people from two worlds in a week.”
”Oh.” Lin Qijing turned his head and said with a scornful smile, ”when did you come to a world?”
”Dry.” Li Zheng pounded the table with anger.
Indeed Never reached a level
But this time it's really different. The physics contest can't fail.
Damn, why wait until April
It's been too long. I can't bear it.
Take the final exam as a killer.
Just then, Liu Xinchong into the classroom, did not put the schoolbag, ran to Li Zheng next to light up the mobile phone: ”there is a force to send the performance video inside the bar, Li brother, you are to be famous ah!”
Li Zheng eyebrows a tight, looking at the screen.
