For each of the languages listed below, give a regular expression that generates the lan- guage. Briefly justify your answer. (a) The set of strings over (a, b such that any a in the string is followed by an odd number of b's. Examples: bbbab E L, but abb f L. (b) The set of strings over fa, b in which there is an a in every even position and the total number of b's is odd, where the first...

The grammartofsm algorithm:
Let L be the language described by the following regular grammar: a. For each of the following strings, indicate whether it is a member of L: v. zyyzz b. Use grammartofsm (Rich 2008; page 157) to construct an FSM that accepts L c. Give a concise (but complete) description of L in plain English. We were unable to transcribe this image

Give an unambiguous grammar for the same language generated by
the grammar:
<fruit>* : -<yellow» | <red> <yellow» banana |mango | <empty> <red> ::- cherry | apple | <empty> "Same language" means that the unambiguous grammar can generate exactly the same set of strings as the ambiguous grammar. No more; no fewer. There will of course be a difference in how - by what NTSs and productions - at least some of those strings are generated
