Maximum single-sell profit
...pective max and min.
If we use this approach, our recurrence relation is now
T(1) <= O(1)
T(n) <= 2T(n / 2) + O(1)
Using the Master Theorem here gives us a runtime of O(n) with O(lg n) space, which is even better than our original solution!
But wait a minute - we can do even better than ...
