Can someone help me to explain why the other options are incorrect? I know which options is the answer but can't understand why the other options aren't. I feel some of them are correct too but there is only 1 correct answer. ======== For your info: - PDA stands for "Pushdown Automata" - e: epsilon ( a space character) - Meaning of the transitions: A, B/C means "if read the A symbol, pop B out of the stack and push C in the stack". So 0, 0/e = if reads a 0, pop a 0 and push an epsilon in the stack and so on ...
