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...

1. (1 point) Which of the following is true? A. Every regular language is a context-free language. B. Every context-free language is a regular language. C. If a language is context-free, then there exists a pushdown automata to recognize it. D. The set of context free languages is strictly larger than the set of regular languages. E. Each of A,C, and D is true. 2. (1 point) The following diagram shows a context free grammar with start variable S and...

Construct context-free grammars that generate the given set of strings. If the grammar has more than one variable, we will ask to write a sentence describing what sets of strings expect each variable in the grammar to generate. For example, if the grammar was: I could say "C generates binary strings of length one, E generates (non-empty) even length binary strings, and O generates odd length binary strings." It is also fine to use a regular expression, rather than English,...
