code:

#include <bits/stdc++.h>
using namespace std;
int n;
int x;
int a[100001];
int b;
int main()
{
	cin>>n;
	for (int i=1;i<=n;i++) {
		cin>>a[i];
	}
	cin>>x;
	for (int i=1;i<=n;i++) {
		if (x>a[i]) {
			x-=a[i];
			b++;
		}else if (x<a[i]) {
			a[i]=a[i]+1;
		}
		if (b==n) {
			break;
		}
	}
	cout<<b<< endl;
	return 0;
}
