public class magic
{
    public static void main (String args[])
    {
        Scanner sc = new Scanner(System.in);
        System.out.println("ENTER NO TO CHECK");
        int num = sc.nextInt();
        String str = Integer.toString(num);
        int len = str.length();
        int count = 0;
        int i;
        for(i=0 ; i <len ; i++)
        {
            if ( str.charAt(i) == '0')
            count ++;
        }
        
        
        if(count > 0 && str.charAt(0) != '0')
        System.out.println("It is a Duck Number");
        else
        System.out.println("It is not a Duck Number");
