Question

Given a DFA for the following languages, specified by a transition diagram. For each one of them, give a short and clear description of how the machine works. Assume the alphabet is Σ = {0,1,2}:

(a) L1 = {w | w is any string over Σ that contains at least one ’0’.}
(b) L2 = {w | w contains even number of 0s and an odd number of 1s.}
(c) L3 = {w = 0u12v | u,v are any strings over Σ.}
