getOnesDigit:  Extract the ones digit from an integer.

Write a function called "getOnesDigit" that takes an integer parameter, and returns the value of the ones digit.
(getOnesDigit 125) --> 5
(getOnesDigit 51239) --> 9
(getOnesDigit 2) --> 2
Note: the remainder function does not work on this website, you must use modulo: (modulo a b). Modulo is not the same as remainder but works the same with positive values)
