2. = {a,b,c}, L = {r : # () > # (1) > # (0)}. Prove that L& CFLs using the CF pumping theorem. Remember that r is only defined in the characteristic function of L; that the only valid assumption you can make about k, the pumping length, is that it is greater than zero; and that w, the "long" string in L you will define for your proof, must be specified in terms of k
