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...

Automata theory Q1: Assume S = {a, b}. Build a CFG for the language of all strings with a triple a in them. Give a regular expression for the same language. Convert the CFG into CNF grammar. Q2: Assume S = {a, b}. Build a CFG for the language defined by (aaa+b)*. Convert the CFG into CNF grammar. Q3: Explain when a CFG is ambiguous. Give an example of an ambiguous CFG. give vedio link also

3. Create a CFG describing regular expressions over the alphabet {0, 1}. You will need to quote the regular expression operators and the template given you has them quoted as terminals. We expect the grammar to generate the following syntactic constructions: • Union via "|", for example, 0 1 "|" 1 should be in the language generated by the grammar • Intersection via "&", for example, 0 1 "&" 1 should be in the language • Concatenation: any nonempty sequence...
