ABSTRACT
The pattern of a programming contest problem is input-process-output. A problem for simple computing is a problem whose process is simple. For such a problem, we should only consider optimizing the process and dealing with input and output correctly. The goals of Chapter 1 are as follows:
1. Students master C/C++ or Java programming language. 2. Students become familiar with online judge systems and programming environments. 3. Students begin to learn how to transfer a practical problem into a computing process, imple-
ment the computing process by a program, and debug the program to pass all test cases.
