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

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.

## Which of the following is the goal state of Tower of Hanoi?

The goal is to move all the disks from the leftmost rod to the rightmost rod. To move N disks from one rod to another, 2^ −1 steps are required. So, to move 3 disks from starting the rod to the ending rod, a total of 7 steps are required.

## What does Tower of Hanoi measure?

The Towers of Hanoi and London are presumed to measure executive functions such as planning and working memory. Both have been used as a putative assessment of frontal lobe function.

## Which of the following can be used to solve the Tower of Hanoi problem?

Explanation: The Tower of Hanoi involves moving of disks ‘stacked’ at one peg to another peg with respect to the size constraint. It is conveniently done using stacks and priority queues. Stack approach is widely used to solve Tower of Hanoi.

## How many states are in the Tower of Hanoi?

The number of (legal) states in the N-disk Towers of Hanoi puzzle is 3N.

## What is the goal and all the rules of Tower of Hanoi problem?

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.

## Why is the Tower of Hanoi recursive?

Using recursion often involves a key insight that makes everything simpler. In our Towers of Hanoi solution, we recurse on the largest disk to be moved. … That is, we will write a recursive function that takes as a parameter the disk that is the largest disk in the tower we want to move.
