The Tower from Hanoi

First pick at the stack, where the 
disk you want to move. The upper 
disk will be moved up, then pick at 
the stack to which you want the disk 
moved. This disk will be moved if it 
is possible. Otherwise you will hear 
a beep (when the upper disk in the 
stack smaller than the disk you want 
to move).

Run Hanoi.exe to begin.
