Trim the Judges' Scores

Olympic rules: toss the single highest and single lowest score, average the rest. 🤸

You get at least three scores (the trimmed average always comes out whole). Print it.

Example:

Input: scores = [6, 9, 4, 7, 9] Output: 7

Sorted, the list becomes [4, 6, 7, 9, 9]. Trimming the lowest (4) and highest (9) leaves [6, 7, 9], which averages to 7.
