给定一个字符串,求不相同的子串的个数. 假如给字符串“ABA";排列的子串可能: A B A AB BA ABA 共3*(3+1)/2=6种; 后缀数组表示时: A ABA BA 对于A和AB height[i]=1; 表明一个长度公共,所以ABA中多出现了A这个子串,所以6-1=5: 对于ABA BA height[i]=0,所以不需要减去. 最后答案为5: #include<iostream> #include<stdio.h> #include<string…
A string s is called an (k,l)-repeat if s is obtained by concatenating k>=1 times some seed string t with length l>=1. For example, the string s = abaabaabaaba is a (4,3)-repeat with t = aba as its seed string. That is, the seed string t is 3 charac…
