Alphabetical Shelf Check

The dictionary section must be alphabetical, or the librarian loses sleep. 😴

You get the shelf as a list of words. Print perfect if they're in alphabetical order (repeats allowed), otherwise reshelve.

Example:

Input: words = ["ant", "bear", "cat"] Output: perfect

"ant" < "bear" < "cat" alphabetically, so nothing's out of place — print perfect.
