Closest Match

The paint store's sorted shade chart doesn't have your exact color number — take the nearest one. 🎨

You get a SORTED list of nums (at least one) and a target. Print the value closest to the target. If two values tie, print the smaller one.

Example:

Input: nums = [10, 20, 30], target = 24 Output: 20

24 sits between 20 and 30 — comparing distances (4 vs 6), 20 is closer.
