For all suciently long strings z in a context free language l, it is possible to nd two substrings, not too far apart, that can be introduction applying the pumping lemma proof of the pumping lemma. Note that the choice of a particular string s is critical to the proof. Pumping lemma for context free language extra questions, long questions & short questions for computer science engineering (cse) on edurev as well by searching above.
But the converse of the pumping lemma is false:
They are more general (and include) regular languages. Chinese university of hong kong. The following screen should come up. By the pumping lemma this must be representable as , such that all are also in.

The pumping lemma gets its name from the idea that we can pump this substring xi+1. No matter how the pumping lemma splits s into uvwxy. The pumping lemma gets its name from the idea that we can pump this substring xi+1. This is how we will prove that infinite languages such as the set of all palindromes is not regular. • to show how this is possible we must be able to convert any cfg into cnf. Coming to the question, the main application of pumping lemma for regular language is mainly to prove that the given language is not regular.
