Introduction
DFA:
The Deterministic Automaton (DFA) is just a mathematics paradigm for pattern recognition in strings. It consists of a finite number of states, a set of input symbols, a transition function that maps the current state and input symbol to the next state, and a set of accepting states. The DFA starts in a designated start state and reads input symbols one at a time, transitioning between states until it reaches an accepting state or the input is exhausted.
To find:
Construct the DFA.
