Recursive Method for Calculating Factorial
Write a factorial function that takes a positive integer, as a parameter and prints the result of ( factorial).
Note: If you fail to use recursion or fail to name your recursive function factorial or Factorial, you will get a score of .
A single integer, (the argument to pass to factorial).
Print a single integer denoting .
Consider the following steps:
From steps and , we can say ; then when we apply the value from to step , we get . Thus, we print as our answer.
