The Middle Kid

The seesaw referee must be the middle-est kid: as many kids lighter than them as heavier. ⚖️

You get an ODD number of weights. Print the middle value after sorting — the median!

Example:

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

Sorted, the list becomes [10, 20, 30] — the middle position holds 20, the median.
