Bazinga HDU 5510 Bazinga(双指针) 题链 解法:对于串i来说,如果串i是不符合的,那么代表串i之前的字符串都是i的子串,那么我们求一个新的i(定义为ti),如果i是ti 的子串,那么串i之前的字符串都没必要再匹配了,如果不是,ti就是符合要求的答案之一 #include <cstdio> #include <iostream> #include <cstring> using namespace std; const int N=2005; ch…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=5510 题意:至多50组数据,每组数据至多500个字符串,每个字符串的长度最长为2000.问最大的下标(从1开始)j,使得存在i < j使得s[i]不是s[j]的子串: 思路:KMP很容易想到,因为Trie是处理前缀串的,不能处理子串.在KMP中,还要优化下,就是父串可以代表子串,并且直接递推处理(用尺取法,每次处理没有父串的串)即可: #include<bits/stdc++.h> usin…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=5510 思路: 一开始直接用KMP莽了发,超时了,后面发现如果前面的字符串被后面的字符串包含,那么我们就不需要用前面的字符串去比较了,把他标记掉就好了. 实现代码: #include<iostream> #include<algorithm> #include<cstring> #include<cstdio> using namespace std; ][];…

http://acm.hdu.edu.cn/showproblem.php?pid=5510 想了很久队友叫我用ufs + kmp暴力过去了. fa[x] = y表示x是y的子串,所以只有fa[x] == x才需要kmp一次. 那么这样的话,如果全部都不互为子串的话,复杂度还是爆咋的. #include <iostream> #include <cstdio> #include <cstring> #include <cmath> #include <…
