Describe pumping lemma for regular languages

WebJul 6, 2024 · For regular languages, the Pumping Lemma gave us such a property. It turns out that there is a similar Pumping Lemma for context-free lan- guages. The proof of this lemma uses parse trees. In the proof, we will need a way of representing abstract parse trees, without showing all the details of the tree.
