@[zhengdaxin](/user/797229) 数组小了
```
#include<bits/stdc++.h>
#define m a[i].money+=
using namespace std;
int n,d,a[1000005],s;
int main(){
cin>>n>>d;
for(int i=1;i<=n;i++)
cin>>a[i];
sort(a+1,a+n+1);
for(int i=1;i<=n;i++)
{
for(int j=i+1;j<=n;j++)
if(a[i]+d>=a[j])s++;
else break;
}
cout<<s;
return 0;
}
```
