I saw this old post on stack overflow of a PDA that accepts a language where there are exactly twice as many … WebDeterministic pushdown automata can recognize only a smaller set of languages, but most modern programming languages are recognizable by a deterministic pushdown automaton. Context This concept has the prerequisites: context-free grammars (Pushdown automata are equivalent in expressive power to context-free grammars.)
