The Towers of Hanoi (or the Towers of Brahma or the Reve's puzzle)
is an old combinatorial puzzle.
The objective is to move n discs
The solution is to move n-1 discs to the "spare" peg. This allows the largest disc to be moved to its destination. Finally move the n-1 discs from the spare peg to their destination on top of the biggest disc. The process of moving the n-1 discs is solved in a like manner.
