15. Give a simple description of the language generated by the grammar with productions SaaA, A -> bS 16. What language does the grammar with these productions generate? A ->B B- Aa
For the following grammar (7 points) 1. B - Ba|A S - ABb A - Aba |A to find a grammar without A productions that generates the same language, we first identify non-terminals that drive A. These non-terminals are: A and B. Then from S - ABb, we construct S from A - Aba, we construct A - from B - Ba, we construct B - So, the grammar without A that generates the same language is:
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

Write a context-free grammar that generates the same language as regular expression which is ab*|c+ (Describe the four components of context-free grammar which are start symbol(S), non-terminals(NT), terminals(T), and set of production rules(P))
Please help me with this... Give a regular grammar that generates the described language. The set of strings of odd length over {a, b} that contain exactly two b's.
Construct a regular grammar G (a" b) c (aa bb)? VT, S, P) that generates the language generated by
Construct a regular grammar G (a" b) c (aa bb)? VT, S, P) that generates the language generated by
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
determine if the language is regular, context-free, Turing-decidable, or undecidable. For languages that are regular, give a DFA that accepts the language, a regular expression that generates the language, and a maximal list of strings that are pairwise distinguishable with respect to the language. For languages that are context-free but not regular, prove that the language is not regular and either give a context- free grammar that generates the language or a pushdown automaton that accepts the language. You need...
