Write a RECURSIVE method that returns the number of times the digits of a number match in position from each end of the number. For example, 57825 has ONE set of digits that match (the 5's at each end). When a number has an odd number of digits, the middle digit matching itself is NOT considered a match. As another example, the number 12344321 has FOUR matches. You MUST solve this RECURSIVELY and you may NOT use any string methods or strings. It may help to write a helper method.
