WebThese languages generated by these grammars are be recognized by a non-deterministic pushdown automaton. Example S → X a X → a X → aX X → abc X → ε Type - 1 Grammar Type-1 grammars generate context-sensitive languages. The productions must be in the form α A β → α γ β where A ∈ N (Non-terminal) 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 −
