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...
print(strStr("BBC ABCDAB ABCDABCDABDE","ABCDABD")) 参考原文:http://www.ruanyifeng.com/blog/2013/05/Knuth–Morris–Pratt_algorithm.html 参考了阮一峰文章中大量的内容,并根据自己的理解情况作了调整。感谢!

KMP算法(Knuth–Morris–Pratt Algorithm),Knuth就是高德纳。 KMP算法是从朴素匹配算法改进而来:就是穷搜匹配。 朴素匹配算法: 原串:ABCDE 模式串:ACD 1. 将原串和模式串左对齐,然后一位一位比较,直到有一个字符不匹配 2. 发现第二位的B和C不匹配,模式串右移一位 3. 重复这个流程,直到找到完全匹配的子串或...
[The Knuth-Morris-Pratt Algorithm in my own words](The Knuth-Morris-Pratt Algorithm in my own words) 接下来将围绕以下几点讲解kmp: 什么是proper prefixes(前缀)与proper suffixes(后缀) 什么是PMT与其计算方式 使用PMT实现kmp算法 proper prefixes & proper suffixes 这里直接套用阮老师的说法来描述前缀与后缀...

We are now ready to see the code in action:Notice how short and concise this code is. I urge you to try and implement it by seeking the longest palindrome and comparing the code. That is it for this post. It was long, but I hope it will help you internalize this algorithm an...
代码实现如下: #include<set> #include<map> #include<queue> #include<stack> #include<cmath> #include<bitset> #include<cstdio> #include<string> #include<vector> #include<cstdlib> #include<cstring> #include<iostream> #include<algorithm>
This article uses a two-dimensional dp array (but the space complexity is still O (M)) to redefine the meaning of the elements, which greatly reduces the code length and greatly improves the interpretability。 PS: The code of this article refers to "Algorithm 4". The name ...
