向右看齐 题目链接 此题可用单调栈O(n)求解 维护一个单调递减栈,元素从左到右入栈 若新加元素大于栈中元素,则栈中元素的仰望对象即为新加元素 每次将小于新加元素的栈中元素弹出,记录下答案 #include<iostream> #include<cstdio> using namespace std; #define N 100010 int n,w[N],stack[N],top,ans[N]; int main() { scanf("%d",&n);…
题目传送门 大概思路就是把这两个数组排序.在扫描一次,判断大小,累加ans. #include<bits/stdc++.h> using namespace std; int x,y,z; ],m[]; long long s; int main(){ cin>>z>>x>>y; ;i<=z;i++) cin>>n[i]>>m[i]; sort(n+,n++z); sort(m+,m++z); ;i<=z;i++){ if…
