Yao Guofeng sat in the chair and then motioned Leng Bingling to sit in the chair opposite him.

He took out a C + + version of the training guide course of the Olympiad of Informatics from the pile of books and handed it to Leng Bingling, "you start with this book."

Leng Bingling took the book he handed over, opened the catalogue and glanced at it. Then she opened the contents of the book at will, glancing East and West. Soon she closed the book.

She was about to speak.

Chen Bin was a second earlier than her and said responsibly, "well, from today on, every day after school, you write to compete for the class. I spend 15 minutes every day to explain to you the basic knowledge of computer, programming, problem solving, reading programs and improving programs. Now let's start with this book!"

Leng Bingling opened her mouth: "Miss Yao..."

Before she finished, Yao Guofeng interrupted, "our time is relatively tight and we are a little tired to learn. If you want to take the road of competition, you must go all out."

Leng Bingling opened her mouth again and wanted to talk, but she didn't have time to say it.

Yao Guofeng raised his hand, stroked his forehead and said sadly, "don't gossip. Let me briefly explain the contents of the book to you now!"

In fact, he accepted Leng Bingling's letter to compete in the class, which is also a very frustrating thing. Originally, he was busy taking five carefully selected Xinjing students from the school to prepare for the competition in October.

However, the leader said that she must accept the student if her grades are good. If Leng Bingling is now a sophomore in senior high school, he is really happy to accept it. Now Leng Bingling is a sophomore in senior high school and has one month to compete. This is a hot potato. Although her grades in various subjects are very excellent, he still doesn't want to accept it.

Since he accepted it, he had to teach from scratch. She can learn as much as she can. She can participate in the competition. If she can't, she won't participate. He was afraid of missing the students' college entrance examination.

He really seriously began to explain the basics of computer: computer common sense, basic system structure, CPU... Overview of the Internet. His mouth was busy, and his hands wrote on the small white board from time to time. It took him about ten minutes to explain the basics of computer roughly.

Leng Bingling always wanted to speak, but Yao Guofeng didn't stop at all. She was embarrassed to interrupt.

He paused and asked, "I just spent such a short time talking about the basics of computer. Do you understand?"

Leng Bingling pursed her lips. "Mr. Yao, I just glanced at this book. The content in the book is basically the same as that I read at home on Friday. I found out the content on Friday." Leng Bingling said implicitly.

Yao Guofeng was suddenly dumbfounded. She kept talking for ten minutes. She said she didn't have to talk by herself. Do you think I'm idle and flustered? You know why you didn't tell me earlier.

He was a little angry and asked in an unhappy voice, "what do you mean? You understand everything in this book?"

Leng Bingling said calmly, "I should know everything!"

"Well, since you understand the contents of the book, I won't say more. I'll find a program to practice for you."

Yao Guofeng glanced at Leng Bingling with some dissatisfaction in his heart and muttered: your good grades in various subjects do not mean that you have strong computer ability. After reading the book of Informatics for a few days, I will see how much you know.
