The following is a recursive function: def countdown(n): if n == 0: return else: countdown(n - 1) countdown(5) In 3-5 sentences, explain the algorithm.

Answer 1

The algorithm is a simple countdown that starts at the given number and recursively decreases by 1 until it reaches zero. It uses a base case of n = 0 to stop the recursion. Each recursive call subtracts 1 from n and makes a new call with the updated value until the base case is reached. In this case, the algorithm will count down from 5 to 0.
