WebEach recursive definition has two separate parts: a base case and a general (or recursive) case. 1. The easily solved situation is called the base case. The base case is a simple case of the problem that we can answer directly; the base case does NOT use recursion. Each recursive algorithm must have at least one base case. WebFeb 4, 2024 · A recursive function must always have at least one base case to make it stop calling itself or it will cause an error. When reading a recursive function, you need … WebA proper recursive function must always have a base case : The base case is a way to return without making a recursive call.
