Chapter 17: learn to type

Chapter 17 Learning to type

In the school library.

Not only books, but also computers.

It's just that the configuration of the computer is extremely low, and the school's information teacher has imposed restrictions on the system, making it impossible to play games.

So basically no students will go to the library to play computers.

Li Chengqian and Ding Ling separated in the library.

Finding a computer that can be turned on and sitting down, Li Chengqian opened the information Tian Wenming gave.

In addition to the review materials mentioned by the teacher, there are also basic computer tutorials, introductory office software, programming software tutorials and other introductory things.

All documents are in word format.

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

"Start skill focus!"

Suddenly, his brain felt extremely clear and agile, and countless auras shone in it.

Immediately afterwards, Li Chengqian activated a skill again.

"Activate skills, think rationally!"

Suddenly, all his emotions were temporarily blocked, and all his thoughts became logical. Based on the increase in memory and comprehension ability, Li Chengqian could clearly feel that his reasoning ability instantly improved countless times.

All distracting thoughts disappeared in his consciousness, and there was only one thought left in his consciousness, which was to learn the knowledge in the U disk.

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

This is still because the mouse is not easy to operate.

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

Then, he quickly opened the introduction to the office software, the 257-page tutorial, the three-piece office suite of protecting text, tables, and slides. Because he had already mastered the page-turning key, Li Chengqian gave up the mouse operation and kept pressing the page-turning key with his finger.

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

In less than 5 minutes, get the office software introductory tutorial!

Li Chengqian did not stop, and opened the programming software tutorial, page 168.

In just 3 minutes, the operation method, shortcut keys, and setting methods of the software were memorized by him and integrated into his own knowledge system. Even the software designer may not be as good as Li Chengqian in understanding the functions of the software interface. .

Immediately afterwards, there are computer test operation questions in competitions over the years.

Li Chengqian is no longer going to read the written test questions, because it is really unnecessary.

Listed in the youth informatics programming competition, the textbooks that need to be learned have been learned by Li Chengqian.

So if there are no accidents in the written test, he will still get a perfect score.

He has never learned the computer-based test questions. This is his shortcoming. With the blessing of rational thinking skills, he immediately thinks of the most critical points.

Review the first question on the materials:

Please write a simple face recognition algorithm?

The moment Li Chengqian saw the question, Li Chengqian's brain naturally gave a solution to the question,

Get the face image, image structure,

Obtain the proportion of facial features and convert them into characteristic numbers,

Get the proportion of the face contour and convert it into a feature number,

Composed to form the face feature value,

Obtain a new face image, calculate the feature value, and compare it with the database.

come to conclusion…

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

Even in places where the calculation is huge, these codes have been replaced by more efficient assembly language.

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

The signature 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 is more than 10 times slower than his code!

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

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

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

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

Youth Informatics Programming Competition has 10 computer-based test questions each year, 5 questions in the preliminary round, and 5 questions in the final round.

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

The entire review material is close to 1000 pages.

This quantity that makes ordinary people daunting, to Li Chengqian, it is pediatrics. His fingers are flying, and he keeps pressing the flip button. He just glances over the standard answers to each question.

In 30 minutes, the computer-based test review material was finished by him.

Li Chengqian carefully read the topic of the competition, and it really wasn't difficult for him.

"The computer-based test is not as difficult as imagined." Li Chengqian is absolutely confident that if the computer-based test is as difficult as the review materials, he can also get a full score in the computer-based test.

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

If you use a computer keyboard to type, Li Chengqian can't touch type, it's still two-finger Zen, typing is very slow.

"For each question, a lot of codes need to be entered. If I don't enter the codes that have appeared in my mind into the computer because of my slow typing, that would be a tragedy."

Knowledge can be upgraded through the full-professional master game, adding points, or obtained through reading books, but hand speed must be practiced.

But Li Chengqian has an advantage that ordinary people do not have, that is, he has memorized all the positions of the letters on the keyboard,

You only need to familiarize your hands with the correct **** on the keyboard to be able to touch type.

At this moment, the usage time of the skill expired, and a line of prompts appeared in front of his eyes.

【You accumulated 60 minutes of reading time, gained 60 experience points, and the remaining experience points in the experience pool are 4817 points. 】

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

Li Chengqian opens the software

Follow the prompts of the TyPass software, and separate your fingers on the keyboard.

Get familiar with one key at a time.

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

But using a computer, and typing with standard fingering, has never been done.

So although he has memorized all the keyboard positions, the hands often don't listen to the brain.

So keep getting errors.

Li Chengqian was not discouraged, he practiced letter by letter.

At the beginning, 9 times out of 10 input were wrong.

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

And the speed of typing is also accelerating.

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