The minimum number of moves can be deduced from the recurrence relation easily. Similar steps can be applied for any number of disks. Then we will move the n-1 disks at peg B to peg C recursively. The first one is the basically a runner to run the actual game class. then we will move the n th disk from peg A to peg C. I have created 2 classes to play Towers of Hanoi. First we will move n-1 i.e., 3 disks from peg A to peg B recursively. If we want to solve for 4 disks then we will apply similar steps as we did for 3. So the required recurrence relation is a n = 2a n-1 +1. A graphical solution to the Towers of Hanoi from 1 to 8 pieces in Java. We are moving n-1 disks two times (first from A to B then from B to C ) and we move the n th disk only once (from A to C ).
After that we will again call the recursive function to move n-1 disks at peg B to peg A. Now if we look there exists a recursion i.e., first we are calling the recursive function to move top n-1 disks from peg A to peg B then we move the nth disk from peg A to peg C. The required output will be the steps to be followed so that the above puzzle is solved like move disk 1 to peg B. No larger disk is kept over a smaller disk.There are n disks are on peg A, objective of the puzzle is to move the stack of disks to peg C, using peg B(if needed) such that Problem statementĬonsider 3 pegs, peg A, peg B and peg C. It is also said that if the task is completed the universe will end and brahma will start the new cycle of universe. Also at one time they can pick only one disk and use the second tower as a help to move the disk. It is said that when brahma created the universe he gave a task to some priests to keep all the disks from first tower to the third tower.īrahma also gave some simple rules/conditions to the priests that they have to keep the plates in ascending order from top to bottom i.e., the smallest disk at the top and the largest disk at the bottom, no larger disk can be placed on top of smaller disk.
Tower of Hanoi puzzle is also know as tower of brahma puzzle. It is said that there is temple of lord brahma in south India where there are three towers, one of the tower has 64 golden disks on it. There are some stories associated with Tower of Hanoi but here we will cover only one.

When you add the dependencies for the first time, the first run might be a little slow as we download the dependencies, but the subsequent runs will be faster.Hello geeks 😉, in this article we are going to discuss about the Tower Of Hanoi problem which is a very famous mathematical puzzle. Users can add dependencies in the adle file and use them in their programs. OneCompiler supports Gradle for dependency management.
Following is a sample program that shows reading STDIN ( A string in this case ). Using Scanner class in Java program, you can read the inputs. OneCompiler's Java online editor supports stdin and users can give inputs to the programs using the STDIN textbox under the I/O tab. The editor shows sample boilerplate code when you choose language as Java and start coding. Getting started with the OneCompiler's Java editor is easy and fast. It's one of the robust, feature-rich online compilers for Java language, running the Java LTS version 17. Write, Run & Share Java code online using OneCompiler's Java online compiler for free.
