In class we defined PDAs as only being able to push a single symbol on the stack at
a time. That is we defined the transitions function delta as taking a state, an input, and a stack
element and outputting a new state and at most ONE stack element.
A generalized PDA allows popping more than one symbol and pushing more than one symbol
onto the stack in a single transition. That is we define a transition function as delta : Q times Sigma times
Gamma
PQ times Gamma
For example, a transition would indicate that on input if
we pop s from the stack we would push s onto the stack.
Prove that generalized PDAs recognize the same set of languages as the PDAs described in
class
