Furthermore, if the length of w is odd, then the middle symbol of w is different from the last. As an example, strings, aa, bb, aba, ababaaabaaba, abababa are in the language L but ?, a,b, aaa, bbb, bba, aaaab, baabaab, are not part of the language. Get the instant assignment help. For this problem you must: draw the state transition diagram of the pushdown automata (you do not need to write the formal definition), explain briefly why your solution PDA is correct.
