Sketch of a deterministic finite automaton (DFA) for the following regular language (type 3):`$$ L ~=~ \{ w \in \{0,1\}^* ~:~ |w|_0 ~\text{mod}~ 2 = 0 \} $$`

This is an infinite language with, for example, the following words \(w\):`$$ L ~=~ \{\varepsilon, 1, 11, 00, 010, 110000,~... \} $$`

This automaton accepts all words \(w\) where the number \( |w|_0\) of zeros is divisible by two (even number of 0s).
