The Heaviest Dragon Egg

Dragon eggs are hatching soon, and the heaviest one always hatches first! 🥚🐉

You get a list of egg weights (at least one egg). Find the biggest weight and save it in best — no max() shortcut, track it yourself.

Example:

Input: weights = [31, 45, 29, 45, 12] Output: 45

Starting with best = 31, each weight challenges it — 45 beats 31 and becomes the new best. Nothing later beats 45, so that's the final answer.
