KMP(Knuth-Morris-Pratt)算法

一、朴素匹配算法也就是暴力匹配算法。设匹配字符串的长度为n，模式串的长度为m，在最坏情况下，朴字符串匹配算法执行时间为O((n - m + 1)m)。假设m = n / 2，那么该算法的复杂度就是Θ(n ^ 2)。因为不须要预处理。朴素字符串匹配算法执行时间即为其匹配时间。 strstr()函...

KMP(Knuth-Morris-Pratt)算法

字符串匹配是计算机的基本任务之一。举例来说，有一个字符串"BBC ABCDAB ABCDABCDABDE"，我想知道，里面是否包含另一个字符串"ABCDABD"？许多算法可以完成这个任务，Knuth-Morris-Pratt算法（简称KMP）是最常用的之一。它以三个发明者命名，起头的那个K就是著名...
