Reprinted from:Http://www.cnblogs.com/zhangziqiu/archive/2011/03/30/ComputerCode.htmlThis article explains the computer's original code, anti-code and complement. And in-depth exploration of why the use of anti-code and complement, as well as

Before we solve this problem, we should understand a few concepts.First, the concept of the original code, the inverse code, the complement　　The inverse code and the complement of positive numbers are the same as the original code;Negative inverse
