可参考:http://jakeboxer.com/blog/2009/12/13/the-knuth-morris-pratt-algorithm-in-my-own-words/(需FQ) 理解过后,编码实现的关键在于next(i)数组的构建,直接求next(i)不好求,因此,在上述参考中,则求前缀和后缀的最大公共长度(模式串已匹配字串长度减去最大公共长度就是模式串要右滑长度),然后其实通过...

Two Way algorithm ,之前的版本是普通的二重循环查找,因此用不着自己写。 而且glibc 的作者一度也写错过,sourceware.org/bugzilla ps. strstr() 还不止一次出过 bug:sourceware.org/bugzillasourceware.org/bugzilla 等等。c - What is the fastest substring search algorithm? 编辑于 2015-01-17 16:30 赞...
KMP 匹配算法是由 "Knuth Morris Pratt" 提出的一种快速的模式匹配算法。 hint:不为自身的最大首尾重复子串长度 1.待解决的问题:假设P为给定的子串,T是待查找的字符串,要求从T中找出与P相同的所有子串,这称为模式匹配问题。 (可以给出子串在T中的位置) (下文中提到的P和T分别为子串和目标串) ...

我觉得 KMP 搜索算法应该有更好的学习姿势,不需要扯概念扯术语,只需要直觉,Algorithm Visualizer 也许是一个可以在直觉上增加理解的好工具。 代码仓库可以通过以下链接或克隆获取: git clone git@github.com:jimboyeah/jitter_search.git git clone https://github.com/jimboyeah/jitter_search.git ...
