@[XPKAAA](/user/474307) 需要花费的钱数最大可能超过 $99999$，所以改一下就行了
```cpp
#include<iostream>
#include<cstdlib>
#include<cstring>
#include<cstdio>
#include<cmath>
#include<algorithm>
using namespace std;
int n,money=0x3f3f3f3f,a,b,temp;
int main()
{
cin>>n;
for(int i=1; i<=3; i++)
{
cin>>a>>b;
if(n%a!=0)
{
temp=n/a+1;
}
else
{
temp=n/a;
}
temp*=b;
money=min(money,temp);
}
cout<<money;
return 0;
}
```
