Factorial of a Number using Recursion # Python program to find the factorial of a number provided by the user # using recursion def factorial(x): """This is a recursive function to find the factorial of an integer""" if x == 1 or x == 0: return 1 else: # recursive call to the...
In this example, the factorial function performs n recursive calls, each adding a new layer to the call stack. Hence, it yields a space complexity of O(n). Moreover, the space complexity becomes O(log n) if the recursion reduces the input size exponentially. Thus, the amount of stack ...
