#
# 2 - REVERSAL
#
# The quickest way to reverse an array is to swap elements at either end, and repeat
# while moving up from the left and down from the right.
#
#   [ a b c d e f ]
#   [ f         a ] - Step 1 we switched A[0] with A[-1]
#   [   e     b   ] - Step 2 we switched A[1] with A[-2]
#   [     d c     ] - Step 3 we switched A[2] with A[-3]
