```cpp
#include <bits/stdc++.h>
using namespace std;
long long n,s,x,maxs=1000000000,a[3],b[3];
int main()
{
cin>>n;
for (int i=0;i<3;i++)
{
cin>>a[i]>>b[i];
x=0;s=0;
while (x<n)
{
s+=b[i];
x+=a[i];
}
maxs=min(maxs,s);
}
cout<<maxs<<endl;
return 0;
}
```

把ans的值调大一些（比如说2147483647）//别问我怎么知道的。。。

晒代码
```cpp
#include <stdio.h>
#include <stdlib.h>
int main()
{
int n,a[4],b[4],c[4],d[4],i;
scanf("%d",&n);
for(i=1;i<=3;i++)
scanf("%d %d",&a[i],&b[i]);
for(i=1;i<=3;i++)
{
c[i]=n/a[i];
if(n%a[i]!=0)
c[i]++;
d[i]=c[i]*b[i];
}
if(d[1]>d[2])
d[1]=d[2];
if(d[1]>d[3])
d[1]=d[3];
printf("%d",d[1]);
return 0;
}
```
