There are three vertical posts, one of which has 10 rings on it. The rings are all of different sizes with the largest ring on the bottom and the smallest on top. Your goal is to recreate this stack on another post. You are only allowed to move one ring at a time and cannot have a larger ring on top of a smaller ring. What is the minimum number of moves?
Once you solve it for ten rings it actually becomes fairly trivial to solve it for any number of rings. It's a math question YAY!
