Question: Finite Languages & Automata a.) Use the Context-Free Pumping Lemma (Theorem 8.1) to prove that the language {a i b j a i b j

Finite Languages & Automata

a.) Use the Context-Free Pumping Lemma (Theorem 8.1) to prove that the language {aⁱ b^j aⁱ b^j : i, j } is not context-free.

b.) Use the result from (a) and closure of context-free languages under intersection with regular sets (Theorem 8.5) to prove that the language {ww : w {a, b}*} is not context-free.
