@[XUYIEN2010RA](/user/772244) 建议这么干，用while未免太慢了
```c++
#include<bits/stdc++.h>
using namespace std;
long long n;
long long a,t,r;
long long b,o,q;
long long c,x,w;
long long s[3];
int main()
{
cin>>n>>a>>t>>b>>o>>c>>x;
s[0] = (n / a + (n % a != 0)) * t;
s[1] = (n / b + (n % b != 0))* o;
s[2] = (n / c + (n % c != 0)) * x;
sort(s,s+3);
cout<<s[0]<<endl;
return 0;
}
```
