You have a three identical poles in front of you however one has rings in the form of a tower labeled ( being on the top, then , all the way down to on the bottom). You are trying to make this same tower on one of the other poles. There are a couple constraints though. You can not move more than one ring at a time and you can't have rings with higher numbers on top of smaller numbers. How many moves does it take to remake the tower on another pole?
