Hello, everyone!

I’d like to share a problem I came up with, which I believe to be quite unique (as I haven’t come across anything similar elsewhere).

I’ve created many problems for various platforms, but Timosh and Number Theory is the one I consider the most original. I hope you find it intriguing!

The problem is quite challenging — only 5 participants managed to solve it under contest conditions. If you’re looking for an even tougher challenge, there’s a harder version available: Timosh and Number Theory #2.

I’d love to hear your thoughts on this problem!
