题意

笔记本的内存和速度是不可兼得的。可是,有一些笔记本是被另外一些“完虐”的,也就是内存和速度都不高于另外某一个笔记本,现在FST想统计一下有多少笔记本被“完虐”。

思路

  • 对笔记本进行排序,然后倒序遍历得出答案

参考代码

#include
using namespace std;struct node{ int x,y;};int cmp(node a, node b){ if(a.x!=b.x) return a.x
>n; for(int i=0; i
>aa[i].x>>aa[i].y; } sort(aa,aa+n,cmp); int ans=0,maxs=0; for(int i=n-1; i>=0; i--) { if(aa[i].y>maxs) maxs=aa[i].y; else ans++; } cout<
