Webdivisible by 3. Figure (1) presents a DFA for this language; the existence of a DFA for the language establishes its regularity. A formal inductive proof establishing that the DFA accepts L3 is beyond the scope of this question. The ﬁrst step in the design is to identify that the DFA must have 3states, viz., one state to denote strings that are WebDFA Transition Function Inductive Proof. Show for any state q, string x, and input symbol a, δ ^ ( q, a x) = δ ^ ( δ ( q, a), x), where δ ^ is the transitive closure of δ, which is the …
