5. (6 marks) Let 2 = {a,b,c,d}. Give context-free grammars that generate the following languages. In each case, also give a derivation of the specified terminal string using your grammar. The derivation beginning from the start variable should indicate each individual derivation step using the notation (b) L2 = {a2ib2i+1,5k+2 | i > 1, k > 1} Derivation for the string: a*bc
