题意:不重叠最长重复子串 后缀数组做法:http://www.cnblogs.com/candy99/p/6227659.html 后缀自动机的话,首先|Right|>=2 然后min(t[u].val,最右r-最左r-1)>=4就可以了 注意判断条件不能写错哦 并且需要两者取min #include <iostream> #include <cstdio> #include <cstring> #include <algorithm> usin…

题目大意 直接用了hzwer的题意 题意:有N(1 <= N <=20000)个音符的序列来表示一首乐曲,每个音符都是1..88范围内的整数,现在要找一个重复的主题."主题"是整个音符序列的一个子串,它需要满足如下条件: 1.长度至少为5个音符. 2.在乐曲中重复出现.(可能经过转调,"转调"的意思是主题序列中每个音符都被加上或减去了同一个整数值) 3.重复出现的同一主题不能有公共部分. 分析 对于区间加一个数也算相同 转化一下就变成相邻两数差相同 变成…

题目大意:给一个整数序列,找出最长的连续变化相同的.至少出现两次并且不相重叠一个子序列. 题目分析:二分枚举长度进行判定. 代码如下: # include<iostream> # include<cstdio> # include<cstring> # include<algorithm> using namespace std; # define mid (l+(r-l)/2) const int N=20000; int SA[N+5],height[N…

题目链接:http://poj.org/problem?id=1743 题目理解起来比较有困难,其实就是求最长有N(1 <= N <=20000)个音符的序列来表示一首乐曲,每个音符都是1..88范围内的整数,现在要找一个重复的主题. * “主题”是整个音符序列的一个子串,它需要满足如下条件: * 1.长度至少为5个音符 * 2.在乐曲中重复出现(可能经过转调,“转调”的意思是主题序列中每个音符都被加上或减去了同一个整数值.) * 3.重复出现的同一主题不能有公共部分. * 所以1,2,3,4…

A musical melody is represented as a sequence of N (1<=N<=20000)notes that are integers in the range 1..88, each representing a key on the piano. It is unfortunate but true that this representation of melodies ignores the notion of musical timing; b…
