This is the problem: http://i.imgur.com/Io7h1en.pngThis 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.Thank you.
Could someone please explain this language to me and its grammar?
