Question: Consider the following language operator, Dequeue as follows, for a given language L over an alphabet Dequeue (L) = {w | w = vw L

Consider the following language operator, Dequeue as follows, for a given language L over an alphabet

Dequeue (L) = {w | w = vw L with |v| = 1}.

That is, Dequeue (L) removes the leftmost symbol of every string in L. Show that Dequeue preserves regularity.
