算法（Algorithm）是指解题方案的准确而完整的描述，是一系列解决问题的清晰指令，算法代表着用系统的方法描述解决问题的策略机制。也就是说，能够对一定规范的输入，在有限时间内获得所要求的输出。-Algorithm (Algorithm) refers to accurate and complete problem-solving program descr iption, a series of clear instructions to solve the problem, the algorithm represents a systematic approach to problem-solving strategies described mechanism. In other words, be able to enter certain norms to obtain the required output within a limited time.
