Tower of Hanoi algorithm 1.- Introduction 2.- Presentation of main ideas and code 3.- Play the Puzzle!! We have three towers (or rods or pegs), and a number of disks of different sizes which can slide into any tower. The mission is to move all the disks to some another tower without violating the sequence of arrangement. Tower of Hanoi : Algorithm. Da sich ein Computerprogramm zur Lösung des Spiels mit wenigen Zeilen schreiben lässt, ist Türme von Hanoi ein klassisches Beispiel für diese Art der Problemlösung. To move the stack to peg B you would have to expose disk 3 and to do that disk 1 and 2 have to be moved to peg C. So by ensuring that you do not break the rules, using the above subsets of 3 steps in the previous case, you would move disk 1 and 2 to peg C, leaving disk 3 exposed with no disk above it. The Tower of Hanoi is frequently used in psychological research on problem solving. Recursion is useful in solving problems which can be broken down into smaller problems of the same kind. Implementation of Tower of HANOI in using C++ program, Learn: What is Tower of Hanoi?How to implement using recursion in C++? But to accomplish the steps 1 and 3, we apply the same algorithm again on a tower of n-1. 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. So it’s like there is a function called dream()dream(), and we are just calling it in itself.
