![]() Uppermost disk(smallest one) of poleC is being moved to poleB.Then,uppermost disk(largest one) of poleA is being moved to poleC.Īgain,uppermost disk(smallest one) of poleB is being moved to poleA.Also uppermost disk(second smallest one) of poleB is being moved to poleC.įinally,all the disks is being moved to poleC. Now uppermost disk(second smallest one) of poleA is being moved to poleB. first pole is A,second pole is B and third pole is Cįirstly all the disks is in poleA and then the uppermost disk(smallest one) is being moved to poleC. Since this is a recursive approach so,it is quite difficult to understand this by just reading the algorithm so,let's take an example to have a better idea of the solution. At last, we will make another recursive call to transfer all the disks from auxiliary pole to destination pole with the help of source pole.If the number of disks in the source pole is left 1 then transfer it to destination pole.This will be handled through base case.First of all, we will make a recursive call to transfer all the disks from source pole to auxiliary pole with the help of destination pole except the last disk.A larger disk can't be placed on a smaller disk.A disk can only be moved if it is the uppermost disk in the pole.There are some rules which needs to be followed at the time of solving this puzzle. As you step through, take notice of the information // you can see. Try using the debugger to // step through the program to find the bugs. ![]() Find those errors, // document a description of the errors and their fix, and fix them. The objective of the puzzle is to move all the disks from one pole (source pole) to another pole (destination pole) with the help of the third pole (auxiliary pole). Recursion The Towers of Hanoi (iii) Solving the ToH for one disc, or even two discs is trivial (moving from tower A to C, using B as the intermediary). Can someone help me with this // UserMenuSolution.cpp : This code contains five errors before it will work as desired. The puzzle starts with the disk in ascending order of size in one pole, the smallest at the top. It consists of three poles and a number of disks of different sizes which can slide onto any poles. We will get started with Tower Of Hanoi Problem now. Time & Space Complexity of Iterative Approach.Iterative Implementation of Tower Of Hanoi.source) // Step 3 above END IF Note that the pseudocode adds a base case: When disk is 0, the smallest disk. 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. Time & Space Complexity Analysis of Tower Of Hanoi In our Towers of Hanoi solution, we recurse on the largest disk to be moved.Recursive Implementation of Tower Of Hanoi.It is used to demonstrate the simple rules to solve a problem and lead to exponential number of steps. Tower Of Hanoi (TOH) is a mathematical puzzle which can be easily solved by recursive algorithm.
