Language/Type: C++ recursion return
Author: Marty Stepp (on 2016/06/16)

Write a recursive function named evenDigits that accepts an integer parameter n and returns a new integer containing only the even digits from n, in the same order. If n does not contain any even digits, return 0.

For example, the call of evenDigits(8342116) should return 8426 and the call of evenDigits(35179) should return 0.
