LCIS HDU - 3308 Given n integers. You have two operations: U A B: replace the Ath number by B. (index counting from 0) Q A B: output the length of the longest consecutive increasing subsequence (LCIS) in [a, b]. InputT in the first line, indicating…
题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=3308 题意:给定n个数,两个操作: U A B:将位置A的数值改成B Q A B:查询[A,B]内最长连续上升子序列的长度. 注意到'连续'一词,可以用线段树维护[L,R]区间内的LICS. 定义结构Node,内部l,r为左右儿子的下标.ls,rs记录当前区间分别从左起和右起的LICS长度,s记录整个区间内的LICS长度. pushup:和一般的区间合并操作一样,但是要注意假如合并的左右子树中间有可…
题目大意:给一个整数序列,m次询问,每次询问某个区间中最长连续上升子序列的长度. 题目分析:线段树区间合并.维护以区间左端开头的.以区间右端点结尾的和区间最长的上升连续序列. 代码如下: # include<bits/stdc++.h> using namespace std; # define LL long long # define mid (l+(r-l)/2) const int N=100000; int w[N+5]; int len[N*4+5]; int l1[N*4+5],…
