getTensDigit:  Extract the tens digit from an integer.

Write a function called "getTensDigit" that takes an integer parameter, and returns the value of the tens digit.
(getTensDigit 125) --> 2
(getTensDigit 51239) --> 3
(getTensDigit 2) --> 0
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)
