Hia all. I would like to request comments and maybe clarificaions on the task and solutions provided in the attached PDF. It was one of our homework tasks and, IMO the provided solution does not solve the task at hand. I'm currently in a dispute with the chief TA about this and so far he has not provided a clear explanation why the provided 'solution' is right. NB. I've translated the task the best I could from german. I think it is a pretty much verbal translation. The task, my own solution and the provided solution are in the PDF. Thanks in advance.
