deterministic finite automaton

A deterministic finite automaton (DFA) is a mathematical model used to represent a machine that can process input based on a set of predetermined rules. It consists of a finite number of states and transitions, where each state represents a specific condition or state of the machine, and each transition defines the action or movement that occurs when a particular input is received. The machine can only be in one state at a time and follows a deterministic behavior, meaning that for a given input, there is only one valid transition that can be taken.
