This is the problem: http://i.imgur.com/Io7h1en.png
This was a problem I saw and I really have 0 clue what the Language means the (**) part, and its solution.
I was wondering if anyone could please help me?
I do know what grammars are and how to read them, but this one was confusing and what I really want to know is how one would approach a problem like this. If I was given this problem, I wouldn't even know where to start.
