Recall that string x is a prefix of string y if a string z exists where xz = y, and that x is a proper prefix of y if in addition x 6= y. In each of the following parts, we define an operation on a language A. Show that the class of regular languages is closed under that operation. A
a. NOPREFIX (A) = {w ∈ A| no proper prefix of w is a member of A}.
b. NOEXTEND(A) = {w ∈ A| w is not the proper prefix of any string in A}.
