Finite Automata & Infinite Languages 🤖

Can a simple machine recognize infinite languages? In this short explainer, we explore Deterministic Finite Automata (DFA), one of the simplest models of computation that can recognize infinite languages. Learn how states, transitions, and accept states work, why some languages are regular while others are non-regular, and how this idea connects to the regular expressions we use in programming today.
