WebOct 30, 2024 · The pumping lemma for context-free languages tells you whether the language is or is not context free. That is, if a language satisfies the pumping lemma for context-free languages, it is context free; and if it does not, then it is not. WebSep 19, 2012 · Pumping Lemma. Suppose L is context free. By the pumping lemma, there is a length p (not necessarily the same p as above) such that any string w in L can be represented as uvxyz, where. vxy <= p, vy >= 1, and. u v i x y i z is in L for i >= 0. Given a string w in L, either m > n or m < n. Suppose p = 2. Suppose that m > n.
