Prove {0^i #0^j #0^(ij) | i, j ≥ 0} is not context free using the pumping lemma for context free languages.
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.
(Automata): prove using the pumping lemma that the following language is not context-free: where: ; b)using closure properties and the previous proof, show that the following language is not context free language: Really need your help with this, it is important for the test. please explain what you to do so i can study it throughly. thank you very much!

Prove that the following language L is not a Context Free Language using the Pumping Theorem D = { 0, 1, 2, 3, 5} V = { a, e, i, o, u} C = { d, f, g, h, j } ? = D ? V ? C L = { w : amount(D) < amount(V) < amount(C) } "Amount of symbols in w that are elements of D" < "Amount of symbols in w that are elements of V"...
Give a context free grammar for the language L where L = {a"bam I n>:O and there exists k>-o such that m=2"k+n) 3. Give a nondeterministic pushdown automata that recognizes the set of strings in L from question 3 above. Acceptance should be by accept state. 4. 5 Give a context-free grammar for the set (abc il j or j -k) ie, the set of strings of a's followed by b's followed by c's, such that there are either a...
Give a context-free grammar for the following language over = {0, 1}: L={w : w is not a palindrome}
Consider the following languages Li and L2, respectively, and construct a context free grammar for it if it is a context free language; if not, using the pumping lemma to disprove it. Let na(w) denote the number if a is w, same notation for to now) and nc(w). • L1 = {w we {a,b}* and na(w) = nb(w)} • L2 = {w I w€ {a,b,c}* and na(w) = n5(w) = nc(w)}
Prove that the language {anb3nan | n ≥ 1} is not context-free.
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...
