O 1 In computer sciencebinary search, also known as half-interval search,  logarithmic search,  or binary chop,  is a search algorithm that finds the position of a target value within a sorted array.
We will use Recursive algorithm to solve Tower of Hanoi problem. Start peg contains 3 disks of different sizes as shown. You have to move all the disk from Start peg to End peg using Auxiliary peg. There are few rules that need to keep in mind, 1. Only one disk can be moved at a time.
Lets understand what is the input and the expected output. There is no use of Auxiliary peg when there is only 1 disk, So we directly moved it from source to destination.
So, for total 1 disk, irrespective of the Peg it is present, moving it to any other Peg requires only 1 step. In our recursion, this will be our base case. When the disk remaining is only 1, then directly move it from Start to End. Move disk 1 from peg A to peg Help, 2.
Move disk 2 from peg A to peg B, 3. Move disk 1 from peg Help to peg B. So this say, for moving 2 disk from Peg A to Peg B, it requires 3 steps.
In general we can say, for 2 disks, it requires minimum 3 Steps to move disks from any source peg to any destination peg. We already know how to solve problem with 2 disk. In our Towers of Hanoi problem, If there is more then 2 disk, then recurse on the disk until only one disk is remaining.
That is, we will write a recursive function that takes below parameter, 1. Disk that need to be moved. Source Peg from where the disk need to be moved, 3.
Auxiliary Peg which will be helper peg for performing operation.
Can we make 3 disk tower to 2 disk tower logically 2 disk tower because we already know how to solve 2 disk tower. Yes, by considering 3rd last disk as 1 unit and above 2 disk Disk 1 and Disk 2 as 1 unit, So now it became 2 disk tower.
We already know how to move tower containing 2 disk. How can we move 2 disk all together in one go We are violating rule here. So what we will do is further narrow down that 2 disk sub tower to 1 disk sub tower.
For narrowing down, we will use recursion in which 3rd disk will be in memory and first play with only top 2 disk and move that from Source Peg to Auxiliary Peg.
Now at top only 1 disk is remaining and we already know how to solve it. This steps we are performing to remove nth last disk as that is the largest disk and need to be moved to Destination Peg. We moved top 2 disk from Source to Auxiliary Peg and now the Pegs will look like below, While backtracking, we are left with only 1 disk in Peg A, So directly move it from source peg to destination peg.
Now, all disks from Peg Help need to be moved to Peg B. So, If you have n disk, it can be moved from any peg to any other peg recursively. In all the other cases, we will execute 3 steps recursive procedure.
This leaves nth disc alone on Source peg. Move nth disc from Source Peg to Destination Peg. How recursive solution is working in solving Tower of Hanoi puzzle?
Consider there are N disks in Source Peg that need to be moved to Destination peg. To move all the disk to the destination peg, we first need to move the bottom-most disk from Source peg to the destination peg first because that is the largest disk and will be at bottom of destination peg.
So this is the recursive task and therefore we can write a recursive algorithm. How much minimum steps are required to move all disk from Source peg to Destination Peg? We saw that for 1 disk tower, we required total 1 step to move disk from Source to Destination peg.Program timberdesignmag.com prints the binary representation of a decimal number n by casting out powers of 2.
