Hello, I wanted to thank BledDest and awoo for their good CONTEST, especially questions e and b.
I think there were beautiful questions and overall it was a good essay and I am satisfied with my positive answer :)
I wanted to thank them for the recent EDU contest, which I know are very difficult to plan
As a thank you to BledDest and awoo, I say this sentence to them in Persian.

Eother than $$$max(A)- \sum gcd(g, max(A)-A[i])$$$ or $$$max(A) + \sum gcd(g, max(A)-A[i])$$$ would fail.awoo has a really respectable mother. Do you know her ?
