Last One In

The clubhouse door log records everyone who walked in, in order — and some kids came back several times. 🚪

You get a list of names and a target. Print the position (from 0) of the LAST time the target walked in. The target appears at least once.

Example:

Input: names = ["leo", "mia", "leo", "kai", "leo", "mia"], target = "leo" Output: 4

"leo" appears at positions 0, 2, and 4. Scanning the whole list and overwriting the saved position each time leaves 4 — the last one.
