Cyclic Nacklace HDU 3746 KMP 循环节 题意 给你一个字符串,然后在字符串的末尾添加最少的字符,使这个字符串经过首尾链接后是一个由循环节构成的环. 解题思路 next[len]-len的差即是循环部分的长度. 这个是重点.这个题目自己开始没有想明白,看的博客,推荐这个. 代码实现 #include<cstdio> #include<cstring> #include<algorithm> using namespace std; const i…

题意: 求模式串W在母串T中出现的次数,各个匹配串中允许有重叠的部分. 分析: 一开始想不清楚当一次匹配完成时该怎么办,我还SB地让i回溯到某个位置上去. 后来仔细想想,完全不用,直接让模式串向前滑动,即 j = next[j] #include <iostream> #include <cstdio> #include <cstring> using namespace std; + ; + ; char W[maxn1], T[maxn2]; int next[ma…
