Exercise 2 [3 marks] Write a short recursive Java method that determines if a string s is a palindrome, that is, it is equal to its reverse. Examples of palindromes include 'racecar' and 'gohangasalamiimalasagnahog'. Test the method by asking the user to provide string entries to be checked. Hint: Check the equality of the first and last characters and recur (but be careful to return the correct value for both odd- and even-length strings)
