Our definition of a PDA specifies that a PDA can pop zero or one symbols from its stack and can push zero or one symbols onto its stack during a transition. I.e., the transition function is defined as: 8 : Q x (EU{e}) × (TU {e}) → Q × (TU {e})A generalized pushdown automata (GPDA) can pop and push any fixed number of symbolsfrom/on its stack during a single transition.

Question

Our definition of a PDA specifies that a PDA can pop zero or one symbols from its stack and can push zero or one symbols onto its stack during a transition. I.e., the transition function is defined as:

8 : Q x (EU{e}) × (TU {e}) → Q × (TU {e})
A generalized pushdown automata (GPDA) can pop and push any fixed number of symbols
from/on its stack during a single transition. I.e., its trasition function is defined as
8 : Q × £U {e}× I* → Q × T*
Notice that all PDAS are also GPDAS.
Show that PDAS and GPDAS can recognize exactly the same set of languages. I.e., that for
any GPDA, we can construct a PDA that recognizes the same language.
