Pushdown Automata Introduction - TutorialsPoint

WebA pushdown automaton is a way to implement a context-free grammar in a similar way we design DFA for a regular grammar. A DFA can remember a finite amount of information, but a PDA can remember an infinite amount of information. Basically a pushdown automaton is − "Finite state machine" + "a stack" A pushdown automaton has three components − WebIf a grammar G is context-free, we can build an equivalent nondeterministic PDA which accepts the language that is produced by the context-free grammar G. A parser can be built for the grammar G. Also, if P is a pushdown automaton, an equivalent context-free grammar G can be constructed where L (G) = L (P)
