Design a PDA recognizing each of the following languages and draw its state diagram.
Note that the transition function must be in the format of “a, b →c", namely we can only push/pop one symbol
into/from the stack one time upon one input symbol. You will receive 0 point if you push/pop multiple symbols
into/from the stack one time upon one input symbol.
