State C is the final state and D is the dead state it is so because after getting any alphabet as input it will not go into final state ever. Number of states: n+2 Where n is w =n . The above automata will accept all the strings having the length of the string exactly ... WebA DFA represents a finite state machine that recognizes a RE. For example, the following DFA: recognizes ( abc+) +. A finite automaton consists of a finite set of states, a set of transitions (moves), one start state, and a set of final states (accepting states). In addition, a DFA has a unique transition for every state-character combination. photo of a buzzard
