Pushdown Automata (PDAs) are computational devices that are widely used in the field of computational complexity theory. PDAs are a type of finite automaton that extends the capabilities of a regular automaton by incorporating a stack, which allows for the processing of context-free languages. There are two main types of PDAs: deterministic pushdown automata (DPDAs)
