JAVA

Write a Java Program to check if any number is a magic number or not.

public class IBMagicNumber{

   public static void main(String[] args) { 
       int num = 163;  
       int sumOfDigits = 0;
       while (num > 0 || sumOfDigits > 9) 
       { 
           if (num == 0) 
           { 
               num = sumOfDigits; 
               sumOfDigits = 0; 
           } 
           sumOfDigits += num % 10; 
           num /= 10; 
       } 

       // If sum is 1, original number is magic number 
       if(sumOfDigits == 1) {
           System.out.println("Magic number");
       }else {
           System.out.println("Not magic number");
       }
   }
}
