我这是80分的，希望对您有帮助，~~虽然我也没AC~~
```cpp
#include<iostream>
#include<algorithm>
using namespace std;
int n,s,a,b,x,y,i,k[5005],sum=0;
int main()
{
cin>>n>>s>>a>>b;
a+=b;
for(i=1;i<=n;i++)
{
cin>>x>>y;
if(x<=a) k[i]=y;
}
sort(k+1,k+n+1);
for(i=1;i<=n&&(s-k[i])>=0;i++)
{
if(k[i]==0) continue;
s-=k[i];
sum++;
}
cout<<sum;
return 0;
}
