I have been studying the problem of Longest Increasing Subsequence (N log (N)) from the GeeksForGeeks website, but it doesn't make sense to me, and I don't know if their code is right. Can someone explain the algorithm, and also provide working code? Also, can someone tell me how ...
Codeforces 568E. Longest Increasing Subsequence 题解 题目链接:E. Longest Increasing Subsequence题目大意:洛谷题解:首先如果要求的是最长上升子序列的长度是很简单的。因为是严格单调递增,所以每一个数在最长上升子序列中最多只会出现一次,所以对于bb数组中的每一个数只能够取一次的限制可以不考虑,直接考虑传统的O...
[CF568E] Longest Increasing Subsequence [题目链接]https://codeforces.com/contest/568/problem/E[题解]首先注意到一个数最多出现在一个上升子序列中 , 故可以忽略重复数字的影响。不妨令 li,pili,pi 分别表示当 ii 非"空" 时,以 ii 为结尾的最长上升子序列长度和上一项的位置。

We have a collection of numbers that can be used to fill the gaps. Each number from the given collection can be used at most once. Your task is to determine such way of filling gaps that the longest increasing subsequence in the formed array has a maximum size. ...
