Question : Write a program to check whether given number is Magic or not?

A Magic number said to be a magic when we add each digit until its reached less than 10 after that  if value is 1 then number is Magic.

Example :

    28 = 2+8

         =10

     10= 1+0

         =1 

Solution : 

import java.util.*;

public class Main

{

  

    public static void main(String[] args)

    {

       int m,n,j;

      Scanner sc=new Scanner(System.in);

      System.out.print("Enter Number");

      m=sc.nextInt();

      while(m>0)

      {

          if(m<10)

          {

              if(m==1)

                System.out.println("Magic Number");

              else

                  System.out.println("Not A Magic Number");

              break;

          }         

          n=m;

          j=0;

          while(n>0)

          {

              j=j+(n%10);

              n=n/10;

          }

          m=j;

      }

    }

}
