题意:给你两个串,问你第二个串是从第一个串的什么位置開始全然匹配的? kmp裸题,复杂度O(n+m). 当一个字符串以0为起始下标时.next[i]能够描写叙述为"不为自身的最大首尾反复子串长度". 当发生失配的情况下,j的新值next[j]取决于模式串中T[0 ~ j-1]中前缀和后缀相等部分的长度, 而且next[j]恰好等于这个最大长度. 防止超时.注意一些细节.. 另外:尽量少用strlen.变量记录下来使用比較好,用字符数组而不用string //KMP算法模板题 //hdu…

题目大意:两个数组匹配,求子串首次出现的位置. 题目思路:数组长度,比较大,朴素算法的时间复杂度为 m*n超时.KMP的时间复杂度为m+n可行. #include<iostream> #include<algorithm> #include<cstring> #include<vector> #include<stdio.h> #include<stdlib.h> #include<queue> #include<m…
