(简单KMP)只不过比赛的时候用了string.一直超时,改成char就一遍AC,纠结。。。
1、http://acm.hdu.edu.cn/showproblem.php?pid=16862、题目大意:这道题目太纠结了,就是一道直接用KMP模板的题目,比赛的时候居然第一次想成做for循环次的KMP,超时了,后来知道只能用一次KMP了,结果用的string一直超时,后来改成char居然一遍AC,还得好好熟悉算法题目是给出两个字符串a,b,求a在b中出现多少次3、题目:OulipoTimeL

KMP算法
题意:求模式串在待匹配串的出现次数。解法:1、使用朴素解法,遍历模式串一次,然后待匹配串往后移动一个字符。时间复杂度O(nm)。2、使用KMP算法,求出模式串的Next数组,然后对待匹配串匹配,令i是待匹配串位置指针,j是模式串位置指针。当j等于模式串的长度,即完成一次匹配。令j=next[j]回溯即可。AC代码:#include#include#includeusingnamespacestd;

【题目描述】传送门【题解】KMP模板题,之前不大懂KMP,写了这道题之后就比较清楚了。求失配的过程和最后比较的过程差不多,因为每次都是如果不匹配就跳到它失配的位置。至于为什么是这样,可以想象一下失配也就是说头和尾上的一段字符串是一模一样的,那么我们在头上不停地往前跳,也就相当于在结尾不停地往后跳(自己体会一下)。注意一下查找字符串的过程。【代码】#include #include #include
