## What is the problem of Tower of Hanoi?

Initially, all the disks are placed on one rod, one over the other in ascending order of size similar to a cone-shaped tower. The objective of this problem is **to move the stack of disks from the initial rod to another rod**, following these rules: A disk cannot be placed on top of a smaller disk.
