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" < "Amount of symbols in
w that are elements of C"
Express w in terms of the symbols in
?, not in terms of the D,
V, and C subsets

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.
Is the following language context free or not? (prove / disprove using pumping lemma for CFL ) L = {0n 1 0n | n >= 1}
5.) Is the following language context free or not? (prove / disprove using pumping lemma for CFL ) L = {0n 1 0n | n >= 1}
(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!

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...
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.
Use the CFL (Context Free Language) Pumping Lemma to show each of the following language not to be context-free: a) {a^n b^n c^i | i < n} b) {www | w is a binary string over {0,1}} SHOW ALL WORK AND LEAVE NO STEPS OUT!! NEED THIS ASAP! THANKS!!
Prove {0^i #0^j #0^(ij) | i, j ≥ 0} is not context free using the pumping lemma for context free languages.
4. (Non-CFLs) Prove that the following languages are not context-free. (b) The following language over the alphabet {a, b, c}: B = {aix | i ≥ 0, x ∈ {b, c}* , and if i = 1 then x = ww for some string w}. (Careful: B satisfies the pumping lemma for CFLs! Make sure you understand why, but you don’t need to write it down.)
2. (10 points) Use the pumping lemma for context free grammars to show the following languages are not context-free. (a) (5 points) . (b) (5 points) L = {w ◦ Reverse(w) ◦ w | w ∈ {0,1}∗}. I free grammar for this language L. lemma for context free grammars to show t 1. {OʻPOT<)} L = {w • Reverse(w) w we {0,1}*). DA+hattha follaurino lano
