Leng Bingling didn't speak, and after watching him casually open the "Informatics Olympiad One-Book" and take a look, he then entered a lot of code in the computer and stood up, "You try to improve this program." ”

Leng Bingling glanced at the book he had closed, and then at the full screen of the computer.

She was stunned, this question was the real question of the preliminary round of the NOIP popularization group last year, and she spent 3 minutes at home last night to perfect this question.

She opened her mouth and wanted to say that I had already done this question, Mr. Yao.

Before she could say it, Yao Guofeng said before her, "You do it, I'll go and see how they have completed a few procedures, and I'll come over in ten minutes." ”

After speaking, he stood up and paused, "If you don't understand, you can call me." After saying that, he didn't care if Leng Bing Lingming didn't understand, so he left.

Leng Bingling glanced at the monitor, the teacher called perfect, then she will do it.

She stood up, walked over and sat down in the place where Teacher Yao was sitting just now, lowered her head and crackled on the keyboard, and in less than two minutes she was perfected.

She raised her head and turned around, wanting to shout, "Teacher Yao, I'm done." ”

Seeing that Teacher Yao was explaining to a student, she was embarrassed to disturb, she turned her head, glanced at the book on the desktop, and took a copy of the book "Algorithm Competition Book" to read.

After about three minutes, Yao Guofeng's voice sounded in her ears: "Didn't I just ask you to perfect that question?" What books do you read?"

Leng Bingling slowly raised her head, just about to tell him, "It's done." ”

Before the words were spoken, Gambo, who was sitting in the back, said: "Teacher Yao, I have a bug here that I need you to come over and help." ”

Yao Guofeng heard Gambo call him, he looked a little dissatisfied and said to Leng Bingling: "You do the question just now, I'll come over later." With that, he turned and left.

Leng Bingling had no choice but to put the words on her lips back into her stomach.

Bow your head and continue reading.

She reads books much faster than ordinary people, in less than three minutes, she has read 10 pages, she can basically grasp the content of it, she wants to use the computer to operate, while watching, raised her eyes and looked at the computer, the teacher has not yet come to accept the topic, so she has to lower her head and continue to read.

Suddenly there was a flash of lightning and thunder, the thunder was very loud, she was startled, she was sitting just by the window, looking out of the window just happened to be the school playground, she quickly stood up and closed the window, looking out the window, it was pitch black, and the playground could not be seen clearly, it seemed that the rain would not stop in a short time.

She frowned slightly, and when she got home after class in a while, she was going to rush home in the rain.

Yao Guofeng walked over and saw Leng Bingling looking out of the window in a daze, and the displeasure in his heart was even stronger, and he cleared his throat and said "um".

Leng Bingling heard his voice and calmed down, and turned back to sit in the chair.

Yao Guofeng glanced at her desktop, the computer screen was already black, there was a book on the desktop, he glanced at the book on the desktop, "Algorithm Competition Book" has read thirty pages.

He sighed weakly, and asked you to do the question, but you find a book to read, I have no opinion if you want to read the book, can you find some books that you can understand.

Is "The Algorithm Competition Book" a book you read?

The girl wanted to run before she learned to walk.

He asked with some displeasure, "Did I tell you to finish the perfect question?"

"It's done." Leng Bingling clicked the mouse, and the completed question was immediately displayed in front of Yao Guofeng's eyes.
