4. def pairwise[A](as: List[A], sofar: List[A])(f: (A, A) ⇒ A): List[A]

   This function uses an associative binary function "f" to combine elements of a List[A] pairwise into a shorter List[A].

   This function uses an associative binary function "f" to combine elements of a List[A] pairwise into a shorter List[A].

   For instance, List(1,2,3,4,5) results in List(5, f(3, 4), f(1, 2)).

5. def reducePairwise[A](as: List[A])(f: (A, A) ⇒ A): Option[A]

   This function uses an associative binary function "f" to combine the elements of a List[A] into a Option[A].

   This function uses an associative binary function "f" to combine the elements of a List[A] into a Option[A].

   If the list is empty, None is returned. If the list is non-empty, Some[A] will be returned.

   For example, List(1,2,3,4)(f) results in Some(f(f(3, 4), f(1, 2))).
