my code```

#include<bits/stdc++.h>
using namespace std;
int main()
{  
    long long j1,j2,j3;
    int a,s1,s2,s3,q1,q2,q3;
    cin>>a>>s1>>q1>>s2>>q2>>s3>>q3;
    j1=(a/s1+1)*q1;
    j2=(a/s2+1)*q2;
    j3=(a/s3+1)*q3;
    if(j1<j2&&j1<j3)
    cout<<j1;
    else if(j1>j2&&j1<j3)
    cout<<j2;
    else cout<<j3;
    return 0;
}

求大佬帮忙
