I am replying it without seeing other replies.

Is it a puzzle? It is puzzle for 5th grade student, not for engineers!

Hello Drawde,

It IS a pretty simple puzzle (good for me because I can't solve the complicated ones).

More so, it is great to see you and so many other new (or at least newer) participants here. Welcome to CR4 . Sometimes fun , sometimes serious, sometimes TOO serious, sometimes thoughtful, almost always informative. Still, it is a good 'playground' to exchange ideas, and to learn and grow. I hope we see you here often.

Kind regards ...
