题意:统计其中一个子串的出现次数 题解:即KMP算法中j==m的次数 //作者:1085422276 #include <cstdio> #include <cmath> #include <cstring> #include <ctime> #include <iostream> #include <algorithm> #include <set> #include <vector> #include &l…
这个算法去年的这个时候就已经听过了,看毛片算法哈哈..不过理解它确实花了我很久的时间..以致于我一直很排斥字符串的学习,因为总觉得太难了,但是有些硬骨头还是要啃的,这个寒假就啃啃字符串还有一些别的东西吧,KMP的学习我看了好多好多博客才有那么些头绪,复杂度的分析更是无从谈起,不过线性匹配这样的算法实在太流弊了.~题目是水题,但也算是我的第一道KMP吧.~ #include<iostream> #include<cstring> #include<string> #inc…
题目大意 给定一个文本串和模式串,求模式串在文本串中出现的次数 题解 正宗KMP 代码: #include<iostream> #include<cstring> #include<string> #include<cstdio> using namespace std; #define MAXN 10005 ],P[MAXN]; int f[MAXN]; void getFail() { int m=strlen(P); f[]=f[]=; ; i<…
