The Towers of Hanoi problem involves moving a stack of disks from one peg to another, following specific rules.

• The problem consists of three pegs and a number of disks of different sizes.

• The disks are initially stacked in decreasing order of size on one peg.

• The goal is to move the entire stack to another peg, following these rules:

• 1. Only one disk can be moved at a time.

• 2. Each move consists of taking the top disk from one of the stacks and placing it on top of another stack....read more
