Question: Sigma = {a, b, c} L = {w: w = st, s elementof {a, b}*, t elementof {b, c}*, #_b(s) = 2 middot #_a(s), and

Sigma = {a, b, c} L = {w: w = st, s elementof {a, b}*, t elementof {b, c}*, #_b(s) = 2 middot #_a(s), and #_c(t) = 3 middot #_b(t)}. Use the regular language pumping theorem to prove that L is not regular
