In the school library.

Not only are there books, but there are also computers.

It's just that the computer's configuration is extremely low, and the school's information teacher has placed restrictions on the system, so I can't play games.

So basically no students will go to the library to play on the computer.

Li Chengqian and Ding Ling separated in the library.

After finding a computer that could be turned on and sitting down, Li Chengqian opened the information given by Tian Wenming.

In addition to the review materials mentioned by the teacher, it also contains basic computer tutorials, introduction to office software, and programming software usage tutorials.

All documents are in word format.

Li Chengqian was not in a hurry, he opened the computer tutorial first.

"Activate skill focus!"

Suddenly, his brain felt extremely awake and agile, with countless spiritual lights shining in it.

Immediately afterwards, Li Chengqian activated a skill again.

"Activate skills and think rationally!"

Suddenly, all his emotions were temporarily blocked, and all his thoughts became logical. Based on the increase in memory and understanding, Li Chengqian could clearly feel that his reasoning ability had increased countless times in an instant.

All distracting thoughts disappeared from his consciousness, and there was only one thought left in his consciousness, which was to learn the knowledge on the USB flash drive.

The basic computer tutorial had 60 pages and he finished it in 2 minutes. After turning on the rational thinking skills, his reading speed increased, which was about three times faster than before when he only used the skills to focus.

This is because the mouse is not very easy to use.

"It turns out that you can press the page key to turn pages!" Through the tutorial just now, Li Chengqian has mastered all the shortcut keys.

Then, he quickly opened the introduction to office software, a 257-page tutorial, a three-piece office set for protecting text, tables, and slides. Because he had already mastered the page turning key, Li Chengqian gave up the mouse operation and placed his finger on the page turning key and pressed it continuously.

The pages are switching at an extremely fast speed, and one page will be turned in one second.

In less than 5 minutes, you can complete the introductory tutorial of office software!

Li Chengqian kept going and opened the programming software usage tutorial, page 168.

In just 3 minutes, he memorized the software's operating methods, shortcut keys, and setting methods and integrated them into his own knowledge system. Even the designer of the software may not necessarily be as good as Li Chengqian in understanding the software interface functions.

.

Next, there are the machine test operation questions from previous competitions.

Li Chengqian was no longer prepared to read the written examination questions because it was really unnecessary.

The textbooks listed in the Youth Informatics Programming Competition that need to be studied have been completed by Li Chengqian.

So if there are no accidents in the written examination, he will still get perfect marks.

He had never studied the computer-based test questions before. This was his shortcoming. With the help of his rational thinking skills, he thought of the most critical points in an instant.

The first question on the review material:

Please write a simple face recognition algorithm?

The moment he saw this question, Li Chengqian's brain naturally came up with a solution to the problem.

Obtain face images, image structure,

Get the facial features proportions and convert them into feature numbers,

Get the facial contour proportions and convert them into feature numbers,

Composed to form facial feature values,

Obtain new face images, calculate feature values, and compare with the database.

come to conclusion……

Then, functions and lines of code appeared in Li Chengqian's mind.

Even in computationally intensive locations, these codes have been replaced by assembly language that performs more efficiently.

Only 58 lines of code are needed to realize the face recognition function!

The iconic answer to this question is 287 lines of code.

After reading the standard answer, Li Chengqian discovered that the execution efficiency of the standard answer was more than 10 times slower than his code!

Suddenly, Li Chengqian understood the true purpose of rational thinking.

In a state of rational thinking, Li Chengqian's way of thinking is similar to the way computer hardware operates.

In this state, the program he wrote fits the hardware and can run on the computer with extremely high efficiency.

Moreover, in this state, given a problem, rational thinking will instantly provide the optimal solution based on Li Chengqian's knowledge system.

There are 10 computer test questions every year in the Youth Informatics Programming Competition, 5 in the preliminary round and 5 in the final.

Teacher Tian Wenming collected 10 years of questions, with a total of 100 questions.

The entire review material is close to 1,000 pages.

This quantity, which is daunting to ordinary people, is child's play for Li Chengqian. His fingers are like flying, and he keeps pressing the flip button. He only glances at the standard answer to each question.

He finished reading the review materials for the computer test in 30 minutes.

Li Chengqian read the competition topic carefully and found that it was really not difficult for him.

"The computer-based test is not as difficult as expected." Li Chengqian has absolute confidence. If the difficulty of the questions in the computer-based test is comparable to the review materials, he can also get full marks in the computer-based test.

"I have to practice my hand speed!" For him, there is no problem in solving problems. On the contrary, he is not familiar with the keyboard and typing slowly may hinder his exam.

When typing using a computer keyboard, Li Chengqian was unable to do touch typing. He still had two-finger meditation and his typing was extremely slow.

"Each question requires the input of a large amount of code. It would be a tragedy if I did not input the codes that have appeared in my mind into the computer because I type slowly."

Knowledge can be upgraded and gained through professional master games, or gained by reading books, but hand speed must be practiced.

But Li Chengqian has an advantage that ordinary people don't have, that is, he has memorized the positions of all the letters on the keyboard.

You only need to get your hands familiar with the keyboard using correct fingering techniques to be able to touch type.

At this moment, the time for using the skill ended, and a line of prompts appeared in front of him.

[You have accumulated 60 minutes of reading time, gained 60 experience points, and have 4817 remaining experience points in the experience pool.]

Li Chengqian didn't care. After searching on the computer, he found that the Typing Tool software for practicing typing was installed on the computer.

Li Chengqian opened the software

Follow the prompts of the Typing software and place your fingers on the keyboard apart.

Get familiar with it key by key.

In his previous life, he basically used mobile phones. He was quite familiar with typing on mobile phones, but not with computers.

But using a computer and typing correctly using standard fingering has never been possible.

So although he has memorized the positions of all the keyboards, his hands often don't follow the instructions of his brain.

So it keeps going wrong.

Li Chengqian was not discouraged and practiced letter by letter.

At the beginning, I entered 10 times and 9 times were wrong.

After practicing for a period of time, the number of errors has been reduced to about 7 times.

And the input speed is also increasing.

When Li Chengqian was practicing typing, Bi Jialiang, who was also reading materials in the library, discovered Li Chengqian.

He stood up deliberately to see what Li Chengqian was doing.

When he discovered that Li Chengqian was using typing software to study and kept making typos, the smile on his face suddenly brightened.
Chapter completed!
