```cpp
#include<bits/stdc++.h>
int main(){
int a,b,i,num,n;
int money[3],min=10000*10000;
scanf("%d",&n);
for(i=0;i<3;i++){
scanf("%d%d",&a,&b);
if(n%a==0){
num=n/a;
}
else{
num=n/a+1;
}
money[i]=b*num;
if(money[i]<min){
min=money[i];
}
}
printf("%d",min);
return 0;
}
```
不知道min=money[0]是什么意思
min设太小了
