Write a program to input a number and check whether it is Disarium Number or not? (135=1^1+3^2+5^3=1+9+125=135)

78)  Write a program to input a number and check whether it is Disarium Number or not?  (135=1¹+3²+5³=1+9+125=135)

import java.util.*;

public class Disarium_num

{

    public static void main(String args[ ])

   {

           Scanner sc = new Scanner (System.in);

           System.out.println("Enter a number");

           int a = sc.nextInt();

           int k = a;

           int c = 0;

           while(k>0)

           {

               k=k/10;

               c++;

           }

           int r = 0;

           k=a;

           for(int i = c;i>=1;i--)

           {

               int d = k%10; 

               int x = (int)Math.pow(d,i);

               r=r+x;

               k=k/10;

           }

           if(r==a)

           {

               System.out.println("Entered number is a DISARIUM Number");

           }

           else

           {

               System.out.println("Entered number is not a DISARIUM Number");

           }

   }

}

Output : 

disarium-number

       Write a program to input a number and check whether it is Odious Number or not? (7…binary…111.no. of ones is 3 and it is odd.so it is odious no.)
