Largest Without Max

Write def largest_of(values: list[int]) -> int that returns the biggest number in the list, which always has at least one element, without using the built-in max: take the first element as the biggest so far, then loop over the list and replace it whenever a bigger value turns up. Do NOT write a main block or any top-level test code; the tests construct the calls. Input: a count on the first line, then that many integers one per line; the tests read them, build the list, pass it to your function and print the value it returns.
