Write the function nearestOdd(n) that takes an int or float n, and returns as an int value the nearest odd number to n. In the case of a tie, return the smaller odd value. Note that the result must be an int, so nearestOdd(13.0) is the int 13, and not the float 13.0.

Hint: Remember that the built-in round function works in surprising ways. Instead of round(n), you should use roundHalfUp(n) from this week's notes. That said, there are good ways to solve this problem without using rounding at all, if you prefer.
