 * // Return the reversal of an integer, i.e., reverse(456) returns 654
 * public static int reverse(int number)
 * // Return true if number is a palindrome
 * public static boolean isPalindrome(int number)
 * Use the reverse method to implement isPalindrome.
 * A number is a palindrome if its reversal is the same as itself.
 * Write a test program that prompts the
 * user to enter an integer and reports whether the integer is a palindrome.
