# Which algorithm example is recursive solution of Tower of Hanoi problem?

Contents

The full Tower of Hanoi solution then consists of moving n disks from the source peg A to the target peg C, using B as the spare peg. This approach can be given a rigorous mathematical proof with mathematical induction and is often used as an example of recursion when teaching programming.

## How do you solve the recursive Tower of Hanoi?

Now to solve the problem, recursively move disk 3 from peg A to peg B. Then disk 1 from peg C to peg A. After which disk 2 can be moved above disk 3 at peg B. The puzzle is finally completed by moving disk 1 from peg A over disk 2 and 3 at peg B.

## What is the recursive function of Tower of Hanoi?

The objective of the game is to shift the entire stack of disks from one rod to another rod following these three rules : Only one disk can be moved at a time. Only the uppermost disk from one stack can be moved on to the top of another stack or an empty rod. Larger disks cannot be placed on the top of smaller disks.

## How do you write an algorithm for the Tower of Hanoi problem?

To write an algorithm for Tower of Hanoi, first we need to learn how to solve this problem with lesser amount of disks, say → 1 or 2.

Algorithm

1. First, we move the smaller (top) disk to aux peg.
2. Then, we move the larger (bottom) disk to destination peg.
3. And finally, we move the smaller disk from aux to destination peg.

## What do you mean by Tower of Hanoi problem explain with suitable example?

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: Only one disk can be moved at a time. … No disk may be placed on top of a smaller disk.

## 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.

## What is the objective of Tower of Hanoi algorithm?

What is the objective of tower of hanoi puzzle? Explanation: Objective of tower of hanoi problem is to move all disks to some other rod by following the following rules-1) Only one disk can be moved at a time. 2) Disk can only be moved if it is the uppermost disk of the stack.

## What are the advantages and disadvantages of recursion?

Advantages/Disadvantages of Recursion #

• To solve such problems which are naturally recursive such as tower of Hanoi.
• Reduce unnecessary calling of function.
• Extremely useful when applying the same solution.
• Recursion reduce the length of code.
• It is very useful in solving the data structure problem.

## Why is it called Tower of Hanoi?

The tower of Hanoi (also called the tower of Brahma or the Lucas tower) was invented by a French mathematician Édouard Lucas in the 19th century. It is associated with a legend of a Hindu temple where the puzzle was supposedly used to increase the mental discipline of young priests.

## Is Tower of Hanoi dynamic programming?
