Hanoi Hard Hack (Posted on 2006-04-23) Difficulty: 3 of 5
In the standard Towers of Hanoi problem, you have three poles: the first has a pyramid of n disks, and the other two are empty. Your task is to move the disks to the third pole, with the restriction that you can move one disk at a time, never putting a larger disk on top of a smaller one.

How many moves would this task take, if ALL moves had to be either to or from the middle pole? (Thus, you cannot move a disk directly from the first pole to the third one, or viceversa.)
