hdu3530 Subsequence 单调队列
题目:在一个序列中找一个最长子串,使得子串的m 维护一个递减的单调队列q1(队首为当前最大),同时维护一个递增的单调队列q2(队首为当前最小),控制最大减最小 小于等于k , 若最大减最小大于等于m,则更新答案。 代码: #include #include #include #include #include using namespace std; const int N = 1e5+10...

Dynamic Programming | Set 4 (Longest Common Subsequence)
首先来看什么是最长公共子序列:给定两个序列,找到两个序列中均存在的最长公共子序列的长度。子序列需要以相关的顺序呈现,但不必连续。例如,“abc”, “abg”, “bdf”, “aeg”, ‘”acefg”等都是“abcdefg”的子序列。因此,一个长度为n的序列拥有2^n中可能的子序列(序列中的每...
