Running Minimum

Write smallest(values: list[int]) -> int that returns the smallest value using one pass and a running lowest variable, without calling min() or sorted(). The list always has at least one value, so lowest starts as the first element and the loop runs over the slice values[1:]. Do NOT write a main block or any top-level test code; the tests construct the calls. Input: one line of space-separated integers; the tests print the value your function returns.
