Index Of The Largest

Write index_of_max(values: list[int]) -> int that returns the index of the largest value, the earliest one when the largest appears more than once, and -1 for an empty list. Start a best index at 0, then loop over range(1, len(values)) and move best whenever a strictly larger value is found. Do NOT write a main block or any top-level test code; the tests construct the calls. Input: one line of space-separated integers (possibly empty); the tests print the index your function returns.
