How to Successfully Play Tower of Hanoi: A Step-by-Step Guide

Introduction

Tower of Hanoi is a classic mathematical puzzle that requires logic and strategic thinking to solve. The objective of the game is to move a stack of discs from one peg to another, following specific rules. This article provides a step-by-step guide on how to successfully play Tower of Hanoi.

Step 1: Understand the Rules

Before diving into the game, it is important to understand the rules of Tower of Hanoi:

1. There are three pegs labeled A, B, and C.
2. A stack of discs of different sizes is placed on peg A. The discs are arranged in decreasing order of size, with the largest disc at the bottom.
3. The objective is to move the entire stack of discs from peg A to peg C, using peg B as an intermediate peg.
4. Only one disc can be moved at a time.
5. A larger disc cannot be placed on top of a smaller disc.

Step 2: Start Solving

Now that you know the rules, you can begin solving the Tower of Hanoi puzzle:

• Start by moving the top disc from peg A to peg C. This can be done by directly moving the disc from A to C.
• Next, move the next smaller disc from peg A to peg B. This can be done by moving the disc from A to C, then from C to B.
• Finally, move the smallest disc from peg A to peg C. This can be done by moving the disc from A to B, then from B to C.
• Repeat the above steps, but this time using peg B as the source peg and peg A as the intermediate peg. The goal is to move the stack of discs from peg B to peg C.

Step 3: Recursive Approach

Tower of Hanoi can also be solved using a recursive approach:

• If the number of discs is 1, simply move the disc from the source peg to the destination peg.
• If the number of discs is greater than 1, follow these steps:

  1. Move n-1 discs from the source peg to the auxiliary peg.
  2. Move the largest disc from the source peg to the destination peg.
  3. Move the n-1 discs from the auxiliary peg to the destination peg.

Conclusion

Playing the Tower of Hanoi can be both challenging and entertaining. By following the step-by-step guide and utilizing a recursive approach, you can successfully solve the puzzle and sharpen your problem-solving skills.
