The check rejecting the cases where (len % 2 == 0) is only correct if the number of digits requested is also odd; it's perfectly reasonable to request the middle 2 digits of a 4-digit number, etc. So the correct check is to reject the case where the length of the string does not have the same parity as the number of digits being requested (len % 2 != n % 2).
