The Pumping Lemma is used for proving that a language is not regular Here is the To prove that a language L is not regular, we use proof by contradiction Here are the steps A wrong choice here will make step 4 impossible 4 By Pumping Combining with (ii) — depending on whether uv is even or odd, v is some
