Pumping lemma for context free languages




2021-4-5 · Pumping Lemma is to be applied to show that certain languages are not regular. It should never be used to show a language is regular. If L is regular, it satisfies Pumping Lemma. If L does not satisfy Pumping Lemma, it is non-regular. Method to prove that a language L is not regular. At first, we have to assume that L is regular. So, the
