1 00:00:00,310 --> 00:00:02,690 So now, let me ask you a second question. We just saw that we 2 00:00:02,690 --> 00:00:04,640 can, reveal a failure in the program 3 00:00:04,640 --> 00:00:06,640 by calling double with parameter three. Where 4 00:00:06,640 --> 00:00:09,750 is the fault that causes such failure in the program? So I want you 5 00:00:09,750 --> 00:00:12,900 to write the number of the line of code that, that contains the fault.
