Find a regular grammar for the language

WebNov 2, 2024 · There is a well established theorem to identify if a language is regular or not, based on Pigeon Hole Principle, called as Pumping Lemma. But pumping lemma is a negativity test, i.e. if a language doesn’t satisfy pumping lemma, then we can definitely say that it is not regular, but if it satisfies, then the language may or may not be regular.
