Question

The following is a recursive function:%0D%0A%0D%0Adef countdown(n):%0D%0A if n == 0:%0D%0A return %0D%0A else:%0D%0A countdown(n - 1) %0D%0Acountdown(5)%0D%0AIn 3-5 sentences, explain the algorithm.

Answer 1

The recursive function named "countdown" takes an integer n as its input. If n is equal to 0, the function simply returns, indicating the base case. Otherwise, it calls itself again with the argument n-1, effectively reducing the number by 1. This process continues until n eventually becomes 0, at which point the function returns in each recursive call and terminates. In this specific code snippet, the countdown function is initially called with the argument 5.
