Prove {0^i #0^j #0^(ij) | i, j ≥ 0} is not context free using the pumping lemma for context free languages.
Prove {0^i #0^j #0^(ij) | i, j ≥ 0} is not context free using the pumping lemma for context free languages.
6.) Is the languages Context Free or not? (prove / disprove using pumping lemma for CFL ) L = {0n 1 0n 10n | n >= 1}
Theory of Computation - Non Context Free Languages
Use the Context-Free Pumping Lemma to prove that the following
language 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.
Let A = {aibjck | i > j > k}. Use the pumping lemma for context-free languages to show that A is not context-free.
Use the pumping lemma to show that the following languages are not context free: a)0^n0^2n0^3n;n>=0 b) {w#x \ where w.x e {a,b) * and w is a substring of x} c) (a^ib^ja^ib^j|i,j>0) answer should be very clear .otherwise I will down vote .
Does a non-context-free language exist that doesn't break any of the rules of the pumping lemma for context-free languages? Yes. If a language is finite, it will pass the pumping lemma. No. Since the pumping lemma is used to prove a language is not context-free, a non-context-free language has to break the rules of the pumping lemma. No. If the results of a pumping lemma proof are inconclusive, a bad string was chosen. Yes. Otherwise, we could use the pumping...
Use the pumping lemma for context-free languages to prove that
L3 is not a CFL.
L3 = { w: w e{a,b,c}* and na(w) < nh(w) < nc(w) }.
Can someone use pumping Lemma to show if these are regular
languages or not
c) Is L regular? give a finite automaton or prove using pumping lemma. (d) Is L context-free? give a context-free grammar or pushdown automaton, otherwise pr using pumping lemma. (16 pts)Given the set PRIMES (aP | p is prime (a) Prove that PRIMES is not regular. (b) Prove that PRIMES is not context-free. (c) Show if complement of PRIMES (PRIMES ) is regular or not. d)...
