            input=input/2;  
            count++;
        }

        int arr[count];

        while(num > 0)
        {
            arr[i]=num%2;
            num=num/2;  
            i++;
        }
        for(int i=count-1 ; i>=0 ; i--)
        {
            cout<<" " << arr[i]<<" ";
        }



        return 0;
