Example of a factorial time algorithm O( n! )

Question

I\'m studying time complexity in school and our main focus seems to be on polynomial time O(n^c) algorithms and quasi-linear time O(nlog

Answer 1

Here is a simple example with Big O( n! ):

This is in python 3.4

 def factorial(n):
    for each in range(n):
        print(n)
        factorial(n-1)
