直接暴力+O2
```cpp
#include<stdio.h>//TLE吧
using namespace std;
int n,m,sum,maxn=-1e9,ll,lo;int s[100005];
int main(){
scanf("%d%d",&n,&m);
for(int i=0;i<n;i++){
scanf("%d%d",&ll,&lo);
s[ll]+=lo;
}
for(int i=1;i<=100005;i++){
sum=0;
for(int j=i;j<i+m;j++){
if(i+m>100000) break;
sum+=s[j];
}
if(sum>maxn) maxn=sum;
}
printf("%d",maxn);
return 0;
}
```
