``````import java.util.Scanner;

public class MagicNumber
{
public static void main(String[] args)
{
int n, r = 1, num, sum = 0;
Scanner sc = new Scanner(System.in);
System.out.print("Enter number=");
n = sc.nextInt();
num = n;
while (num > 9)
{
while (num > 0)
{
r = num % 10;
sum = sum + r;
num = num / 10;
}
num = sum;
sum = 0;
}
if (num == 1)
{
System.out.println("Magic Number");
}
else
{
System.out.println("Not Magic Number");
}
}
}
