Construct CFGs and pushdown automata that recognize the following languages. (e)

Construct CFGs and pushdown automata that recognize the following languages. (e) C = {w {0,1}* | w=wR} (d) D= {a' blck | i, j, k > 0, and i = j or j =k} (e) E = {abck i, j, k > 0 and i + j=k} (f) F= {a2ny3" | n >0} (g) L = {a' b dk | i, j, k > 0 and i +k=j}
