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

This is an infinite language with, for example, the following words \(w\):$$ L ~=~ \{00, 001, 010, 001,~... \} $$

This automaton accepts all words \(w\) where the number \( |w|_0\) of zeros is exactly two.
