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. WebFind a regular grammar that generates the language on Σ = {a, b} consisting of all strings with no more than two a’s. arrow_forward Find a regular grammar that generates the language L (aa∗ (ab + a)∗). (so, find the NFA first, then each edge in the NFA gives a production in the regular grammer) arrow_forward

Approach: The problem can be accepted only when the following cases are met: All the characters can be ‘a’. All the characters can be ‘b’. All the ‘b’ come occur after all the ‘a’. There is at least one character in the string. heart rate zones apple watch 8
