I tried all the types of input and for me, it is giving all the correct answers. on submission it is giving me "Wrong answers" error. I don't know where. IF YOU KNOW WHERE IS IT GETTING WRONG IN MY PROGRAM. HELP ME TO CORRECT IT.

My code :

include<bits/stdc++.h>

using namespace std; int main(){ ios::sync_with_stdio(0); cin.tie(0); cout.tie(0); long long int n; cin>>n; vector a(n); vector b(n); vector c(n); for(auto &i:a) { cin>>i; }
for(auto &i:b) { cin>>i; }

long long int max1 = a[0];
long long int max2 = b[0];
long long int res, pre_res;
c[0] = 1LL*max1*max2;

long long int m = c[0];
for(long int i = 1 ; i < n; i++)
{
    pre_res =1LL*max1*max2;
    max1 = max(max1,a[i]);
    if(max1>a[i])
    {
        max2 = max(max2,b[i]);
    }
    else {max2 = b[i];}
    res = 1LL*max1*max2;
    if(res > pre_res)
    {
        c[i] = res;
    }
    else {c[i] = pre_res;}
}


for(auto i:c)
{
    cout<<i<<endl;
}
return 0;

}
