建立后缀自动机，对于同一个节点，出现次数是相同的(right的大小)，同时满足单调性（长度越长出现次数越少），所以只需要考虑最长的串即可。 PS：似乎也并不需要求依次后缀的max，不知道为什么…… 1 #include<bits/stdc++.h> 2 using namespace std; 3

SPOJ_7258 SUBLEX
这个题目可以先用O(N)的时间构造出后缀自动机，由于后缀自动机中每条路径都对应着一个不重复的子串，因此可以用dp处理出到达一个节点以及其后面的节点的路径数，然后每次查询时遍历一遍后缀自动机就可以了。
但这样总的查询复杂度是O(N*Q)的，如果不用各种常数优化的话很容易TLE。
