WebTo prove that a given language, L, is not regular, we use the Pumping Lemma as follows . 1. We use a proof by contradiction. 2. We assume that L is regular. 3. It must be recognized by a DFA. 4. That DFA must have a pumping constant N 5. We carefully choose a string longer than N (so the lemma holds) 6. WebTherefore Lis not regular. (b)Show that the pumping lemma for regular languages applies to F. In other words, show that there is psuch that for any w2F with jwj>p, there are x;y;zwith xyz= w, jyj>0, and jxyj 0, xyiz2F. Note: (a) and (b) together show that the converse of the pumping lemma is false. green river college bookstore https://paulwhyle.com
