描述 Given a sequence, we define the seqence's value equals the difference between the largest element and the smallest element in the sequence. As an example, the value of sequence (3, 1, 7, 2) = 7-1 = 6. Now, given a sequence S, output the sum of all…

鉴于早上那题让我怀疑单调栈白学,特意来复习下单调栈 题意 考虑按照每个元素对答案的贡献来统计,那么我们只需要找到每个元素左边右边第一个比它小的就可 这题给的又是排列,简直不能再良心 #include <bits/stdc++.h> using namespace std; #define int long long const int N = 1000005; int s[N],top,a[N],l[N],r[N],n,ans; signed main() { cin>>n; fo…

Problem Description Given a circle sequence A[1],A[2],A[3]......A[n]. Circle sequence means the left neighbour of A[1] is A[n] , and the right neighbour of A[n] is A[1]. Now your job is to calculate the max sum of a Max-K-sub-sequence. Max-K-sub-sequ…

题目链接:hdu 3415 Max Sum of Max-K-sub-sequence 题意: 给你一串形成环的数,让你找一段长度不大于k的子段使得和最大. 题解: 我们先把头和尾拼起来,令前i个数的和为sum[i]. 然后问题变成了求一个max{sum[i]-sum[j]}(i-k<j<i) 意思就是对于每一个sum[i],我们只需要找一个满足条件的最小的sum[j],然后我们就可以用一个单调队列来维护. #include<bits/stdc++.h> #define F(i,a…
