There is a special number sequence which has n+1 integers. For each number in sequence, we have two rules: ● a i ∈ 0,n0,n ● a i ≠ a j( i ≠ j ) For sequence a and sequence b, the integrating degree t is defined as follows("�" denotes exclusive or…

http://acm.hdu.edu.cn/showproblem.php?pid=1711 首次接触KMP,自己都不是特别理解.在网上百度看了好几个帖子之后,对KMP也有了初步的理解. #include <stdio.h> ], b[], next[]; void getnext( int n) { , j=-; next[]=-; while(i<n) { || b[i]==b[j]) next[++i]=++j; else j=next[j]; } } int KMP(int m,…

题意:给你一个a串和一个b串,问b串是否是a串的子串,如果是返回b在a中最早出现的位置,否则输出-1   分析:应该是最简单的模板题了吧..... 代码如下: ============================================================================================== #include<stdio.h> #include<string.h> ; ; int a[MAXN], b[MAXM], next_…

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…
