# include<bits/stdc++.h>
using namespace std;
struct apple{
    int hight;
    int power;
}a[10000];
bool cmp(apple x,apple y){
    return x.power<y.power;
}
int main(){
    int h,l;
    int n,high,k=0;
    cin>>h>>l;
    cin>>n>>high;
    for(int i=1;i<=n;i++) cin>>a[i].hight;
    for(int i=1;i<=n;i++) cin>>a[i].power;
    high+=h;
    sort(a+1,a+1+n,cmp);
    for(int i=1;i<=n;i++){
        if(a[i].hight<high&&l>=0){
            k++;
            l-=a[i].power;
//          cout<<a[i].hight<<" "<<a[i].power<<endl;
        }
        if(l-a[i].power<0){
            break;
        }
    }
    cout<<k;
    return 0;
}为何！！！！
