Disarium Number

Disarium Number in JAVA

A Disarium Number is a number if the sum of its digits powered with their respective position is equal with the number itself.

Example :  1¹+3²+5³ = 135

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 then 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

All the best :)
