Heaviest and Lightest at Once

The moving crew wants both extremes: the heaviest box goes on the bottom, the lightest on top. 📦

You get a list of box weights (at least one). In ONE pass, find both. Print the heaviest, then a space, then the lightest.

Example:

Input: weights = [14, 3, 27, 8] Output: 27 3

Tracking both extremes in one pass, the heaviest box is 27 and the lightest is 3.
