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;
}
