WebThis is recursive because the definition of the factorial of 5 (or any number n) includes the definition of the factorial of 4 (the number n – 1). In turn, 4! = 4 × 3!, and so on, until you must calculate 1!, the base case, which is simply 1. The factorialByRecursion.py Python program uses a recursive factorial algorithm: Python
