Question

A palindrome is a string that reads the same forwards and backwards, such as "warts n straw" or "radar".
Write a program that will accept a string of characters terminated by a carriage return and will determine whether or not the string is a palindrome. In your program, define a static method called palindrome that begins as follows:


/*****************************************************************

* Precondition: The String input contains letters and blanks in
* positions input[0] through input[length - 1].
* Returns true if the string is a palindrome and false otherwise.

*****************************************************************/

public static boolean palindrome(String input) {


Hint: Use the methods charAt(int index) and toLowerCase( ) or toUpperCase( ) of the String class.

Note:
# Consider uppercase and lowercase versions of the same letter to be equal, so the following will be considered a palindrome by your program:
Able was I ere I saw Elba

It should look like this:

Input the string that needs to be checked if it is a palindrome
(press n to terminate the program):

ah ha

BINGO!! The entered input is a palindrome!

Input the string that needs to be checked if it is a palindrome
(press n to terminate the program):

ah ha!

The entered input is NOT a palindrome.
