题目链接 题意:可重叠的 k 次最长重复子串.给定一个字符串,求至少出现 k 次的最长重复子串,这 k 个子串可以重叠. 分析:与POJ 1743做法类似,先二分答案,height数组分段后统计 LCP>=m 的子串的个数. #include <cstdio> #include <cstring> #include <algorithm> const int N = 2e4 + 5; int sa[N], rank[N], height[N]; int t[N],…
题意:给定一个字符串,求至少出现k 次的最长重复子串,这k 个子串可以重叠. 分析:经典的后缀数组求解题:先二分答案,然后将后缀分成若干组.这里要判断的是有没有一个组的符合要求的后缀个数(height[i] >= mid)不小于k.如果有,那么存在 k 个相同的子串满足条件,否则不存在. #include <cstdio> #include <iostream> #include <cstring> #include <algorithm> using…
