Disarium Number
A Disarium Number is a number if the sum of its digits powered with their respective position is equal with the number itself.
Example : Input : 135
Process : 1^1 + 3^2 + 5^3 = 1 + 9 + 125 = 135
Output : It is a Disarium Number
Algorithm and Program Below :-
Algorithm :-
Input a Number
Store it in another variable
Reverse the number.
Again Reverse the reversed number and store it in a new variable with sum of digits powered with their respective position
Compare the original number with this new number
If both are Equal than the number is Disarium Number
Else it is not a Disarium Number
Program :-
import java.io.*; import java.util.*; class Disarium { public static void main(String args[]) { Scanner in = new Scanner(System.in); int n,p,i=0,rev,res,s=0,sum=0; System.out.println("Enter Number"); n= in.nextInt(); // Entering Number p=n; // Storing entered number in new variable while(p>0) { rev= p%10; s=s*10+rev; // reversing original number p=p/10; } while(s>0) { res= s%10; i++; // i variable used for power sum=sum+(int)Math.pow(res,i); // storing sum of digits powered with their respective position s=s/10; } if(sum==n) // comparing original no. with new number { System.out.println("Disarium Number : "+n); } else { System.out.println("Not a Disarium Number : "+n); } } // end of main } // end of class
Note : The program is written in the easiest way possible so try understand it. If you face any problem in understanding this program than feel free to contact/comment.
All the Best :)
Keep Learning :)
