I have a question from a test in a Programming Languages class that is confusing me.
Give a context-free grammar to generate the following language
L = { aibjck | 0 <= i <= j <= i + k }
I am completely unfamiliar with this notation. I cant seem to find anything in the book or my notes about it, and I have no idea how to query google for the answer.
If you recognize it, what is it called and what does it mean?
