「克努斯-莫里斯-普拉特演算法(Knuth–Morris–Pratt algorithm / KMP algorithm)」是一種字串搜尋演算法(string-searching algorithm),可用來在一長串文字中,尋找特定字串。 匹配陣列(PS Array) 用來比較一字串中的內容重複出現的程度;在比較兩字串時,若兩字串不相符,匹配陣列(PS A
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...

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.gitgit clone https://github.com/jimboyeah/jitter_search.git ...

这篇文章将用 C、C++、Java 和 Python 编程语言实现 KMP 算法。 我们已经看到, 朴素算法 用于模式匹配运行 O(n.m) 时间,地点 n 是文本的长度和 m 是模式的长度。这是因为该算法不记得有关过去匹配字符的任何信息。它基本上一遍又一遍地匹配具有不同模式字符的字符。 这KMP 算法 (或者 高德纳、莫里斯和...
