Write a method that returns a string in reverse order. There is a slight "catch" however. If the string has an odd number of characters, omit the middle character from the reversed string. If there are an even number of characters, simply return the reversed string in its entirety. The only string methods you are allowed to use are .length, .equals, .substring, and .charAt. Of course you do not need to use ALL of these methods. Recursion is optional.
