WebIn fact, in this course you will not need to write a loop in a recursive function. Instead you will use if-else (or if-else if) statements. Problems that can be solved recursively have two parts, the base case and the recursive step. A base case can be thought of as a version of a problem for which the answer is known. http://web.mit.edu/6.005/www/fa16/classes/14-recursion/ 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.
