Write two parameterless functions called SORT-TITLE and SORT-YEAR that use QUICKSORT as a helper function to sort the array bound to *db* in ascending order based on either the movie's title or year, respectively. SORT-TITLE and SORT-YEAR return NIL if the movie database is empty; otherwise, they return the array bound to *db* sorted in ascending order (by title or by year, respectively).
