Length Without Len

Complete length(values: list[int]) -> int so it returns how many items the list holds, by recursion and without calling len(). The base case is written: an empty list has 0 items. Add the recursive case, which returns 1 plus the length of 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 integers separated by spaces (it may be empty), which the tests read into a list and pass to your function before printing the value it returns.
