The Fair Middle

An even number of kids — no single middle! The referee weight is the average of the two middle kids (it always comes out whole here). ⚖️

You get an EVEN number of weights. Sort, take the two middle values, and print their average.

Example:

Input: weights = [10, 30, 20, 40] Output: 25

Sorted, the list becomes [10, 20, 30, 40] — the two middle values are 20 and 30, averaging to 25.
