Formal Languages Questions
A finite automaton, also known as a finite state machine, is a mathematical model used to describe and analyze the behavior of systems that can be in a finite number of states at any given time. It consists of a set of states, a set of input symbols, a transition function that defines the state transitions based on the current state and input symbol, an initial state, and a set of final states. Finite automata are widely used in computer science and formal language theory to study and solve problems related to regular languages and regular expressions.
