    public static void main(String args[])
    {
        System.out.println(GD.a);
    }
}

    }
    public static void main(String args[])
    {
        GD g=new GD();
        GD k1=new GD();
        GD k2=new GD();
    }

    }
    public static void main(String args[])
    {
        GD g=new GD(1+1);
        GD k1=new GD(20);
    }
