The countdown function is a recursive algorithm designed to count down from a specified number \( n \) to 0. If the input \( n \) is 0, the function simply returns and does nothing further. Otherwise, it recursively calls itself with the argument \( n - 1 \), which continues this process until \( n \) reaches 0. When calling countdown(5), the algorithm will make a series of calls: countdown(5), countdown(4), countdown(3), countdown(2), countdown(1), and finally countdown(0), where the countdown effectively ends.
