1. Îs the language Li = {aPble" | p,q,r > 1 and r = pg) a context-free language? Prove your answer. 1. Îs t...
Prove that the language L = {a^pb^qc^r|p,q,r >=1 and pq = r} is not context free using pumping lemma. I honestly just need help coming up with a string that works, thanks.
Is the language L = {a^pb^qc^r | p,q,r >= 1 and r =pq} context free?
[4 points) Prove that the following language over = {a,b,c} is not context free: Li = {w/w has equal numbers of a, b, c's}.
Prove that the language {anb3nan | n ≥ 1} is not context-free.
use the pumping lemma for context free languages to prove the language is not context free. B = {w#t | w is a substring of t, where wit e {a,b}*}. Hint: consider s = apbº#apba.
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 arc 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...
5. Is the following language A context-free? You either show that A is context-free by giving a context-free grammar for A, or prove that A is not context-free language using the context-free language pumping lemma
Is the following language context free or not? (prove / disprove using pumping lemma for CFL ) L = {0n 1 0n | n >= 1}
