This test is originally implemented in JavaScript, but I have implemented a C++ version of it as well. See makefile for compiler information.
####### TASK 1: IMPLEMENT: C - binomial coefficient
- C(n,k) = n! / [ k! (n - k)! ] Where x! is the factorial of x
- Use a recursive solution.
####### TASK 2: IMPLEMENT: Test functions
- Write a set of as many tests as needs in order to validate binomial coefficient function.
