Tower of Hanoi is a mathematical puzzle where we have three rods and n disks. Tower of Hanoi is a mathematical puzzle where we have three rods and n disks. Before getting started, let’s talk about what the Tower of Hanoi problem is. Each move consists of taking the upper disk from one of the stacks and placing it on top of another stack i.e. Tower of Hanoi is a mathematical puzzle where we have three rods and n disks. The objective of the puzzle is to move the entire stack to another rod, obeying the following simple rules: edit Conclusion. Well, this is a fun puzzle game where the objective is to move an entire stack of disks from the source position to another position. In the previous section we looked at some problems that were easy to solve using recursion; however, it can still be difficult to find a mental model or a way of visualizing what is happening in a recursive function. edit The Tower of Hanoi (also called the Tower of Brahma or Lucas' Tower and sometimes pluralized as Towers) is a mathematical game or puzzle.It consists of three rods and a number of disks of different sizes, which can slide onto any rod. In addition, the steps outlined above move us toward the base case by reducing the height of the tower in steps 1 and 3. Experience.
