KMP 改进的字符串匹配算法,由D.E.Knuth与V.R.Pratt和J.H.Morris同时发现，因此人们称它为克努特——莫里斯——普拉特操作（简称KMP算法）。KMP算法的关键是根据给定的模式串W1,m,定义一个next函数。next函数包含了模式串本身局部匹配的信息。-Improved KMP string matching algorithm, by DEKnuth with VRPratt and JHMorris also found, so people call it Knuth- Morris- Pratt operations (referred to as the KMP algorithm). KMP algorithm, the key is given of a pattern W1, m, define a next function. next function mode of the string itself contains a partial matching.
