A palindrome is a string that will spell the same way forward and backward. Some examples of palindromes are "radar", "able was I ere I saw elba" and (if blanks are ignored) "a man a plan a canal panama". Write a recursive method testPalindrome that returns boolean value
true if the string stored in the array is a palindrome and false otherwise. The method should ignore spaces and punctuation in the string. [Hint: Use Sting method toCharArray, which takes no arguments, to get a char array containing the characters in the String. Then pass the
array to a method testPalindrome.].
