在文本串中找出现次数最多的子串. 思路:AC自动机模板+修改一下print函数. #include<stdio.h> #include<math.h> #include<stdio.h> #include<stdlib.h> #include<iostream> #include<string> #include<memory.h> #include<map> #include<queue> usi…

input n 1<=n<=150 word1 word2 ... wordn 1<=len(wirdi)<=70 s 1<=len(s)<=1000000 output 最多出现次数 出现最多的串,按输入顺序输出,可能出现相同串,也要输出 做法:用一个end数组记下每个串结尾的字符的下标,对应val为1,每次找到就将val++,然后找到最大的val,输出最大val对应的字符串 #include <cstdio> #include <queue>…

AC自动机的裸题.学了kmp和Trie以后不难看懂. 有一些变化,比如0的定义和f的指向,和建立失配边,以及多了后缀连接数组last.没有试过把失配边直接当成普通边(一开始还是先这样写吧). #include<bits/stdc++.h> using namespace std; , maxnds = *+, sigma_size = , maxsubs = ; char str[maxlen]; #define idx(x) x-'a'; int last[maxnds];//后缀连接 为0…
