Purpose: Extra fruitful recursion practice.

NOTE: This file does NOT contain optimism tests, nor is there a separate
testing file. YOU are responsible for testing these functions, and you
should fill in the docstrings with examples BEFORE you start to write the
code for each. If you use 'doctest' style examples, the code at the end
of the file will check them for you (see the comment down there).

def sumOfEvens(n):
    """
    Returns the sum of all even numbers up to and including
    n (assuming n is even, or up to n - 1 if n is odd).
    For example:

def isPalindrome(word):
    """
    Returns True if the word is a palindrome and False if not.
    Counts the empty string as a palindrome.

def onlyLarger(numbers, threshold):
    """
    Returns a new list of numbers that includes only the numbers
    in the given list which are greater than or equal to the
    given threshold.

def logarithm(n, base):
    """
    Returns the (integer) logarithm of n in the given base,
    which is the number of times that n can be divided by the
    base before the result is less than 1 (we won't worry about
    negative values and will just return 0 for any numbers that are
    already less than 1). For example, if n is 10 and the base is 2,
    then the result will be 3, because 10 / 2 is 5, 5 / 2 is 2.5,
    and 2.5 / 2 is 1.25, but 1.25 / 2 is less than 1. We'll
    assume that the base is a positive integer greater than 1.
