Quizplus · Accepted Answer

The Tower of Hanoi problem involves three needles (also called pegs or towers) and a series of disks of varying sizes that can slide onto any needle. The goal is to move the entire tower of disks from one needle to another, but only one disk can be moved at a time and a larger disk cannot be placed on top of a smaller disk.
