A palindrome is a string that reads the same both forward and backward. For example, the string racecar is a palindrome. Write a program that uses a recursive function to check whether a string is a palindrome. Your program must contain a value-returning recursive function that returns TRUE if the string is a palindrome and FALSE otherwise. Do not use any global variables; use the appropriate parameters. Your program should prompt the user for a string to determine if the string is a palindrome.
