@[guosir](/user/790092) 数组开小了，$n$ 可能到 $10000$

我非常疑惑，这样写不香吗，写这么多干嘛：
```cpp
#include <iostream>
#include <cmath>
using namespace std;
int main()
{
double n;
cin >> n;
int a1, a2, b1, b2, c1, c2, j1, j2, j3;
cin >> a1 >> a2;
cin >> b1 >> b2;
cin >> c1 >> c2;
j1 = ceil(n/a1)*a2;
j2 = ceil(n/b1)*b2;
j3 = ceil(n/c1)*c2;
cout << min(min(j1, j2), j3);
return 0;
}
```
