class Duck_number
{
    public static void main(String args[])
    {
     Scanner sc= new Scanner(System.in);
     int n,r,p,c=0;
     System.out.println("Enter the no ");
     n=sc.nextInt();
     while(n>0)
     {
         r=n%10;
         if(r==0)
         c++;
         else
         p=r;
         
        n=n/10;
        
    }
    if(c>0)
    System.out.println("Duck number");
    else
    System.out.println("Not Duck number");
