Binary Search a Sorted List of Ages

The village registry lists every resident's age in sorted order, all different. 🏘️

You get the SORTED ages and a target age that's definitely present. Print its position (from 0) using the split-in-half strategy.

Example:

Input: ages = [7, 12, 19, 25, 31, 44], target = 25 Output: 3

Splitting the range in half repeatedly narrows the search down to age 25, which sits at position 3.
