54)  Write a program to input a number and check whether it is Neon Number or not?(9² = 81 , 8+1=9 , 9=9)

import java.util.*;

public class Neon_number

{

    public static void main(String args[ ])

   {

          Scanner sc = new Scanner (System.in);

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

          int a = sc.nextInt();

          int s = 0;

          int p = a*a;

          while(p>0)

          {

          int d = p%10;

          s=s+d;

          p=p/10;

          }

          if(a==s)

          {

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

          }

          else

          {

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

          }

   }

}
