👉 In programming, a recursive function is a function that calls itself during its execution. This means that every time it's called, it will call itself with smaller and smaller sub-programs until it reaches a base case (the point at which it can stop calling itself). The basic idea behind recursion is to break down complex problems into simpler parts that can be solved independently of each other, or to solve the same problem in different ways. For example: ```python def factorial(n): if n
