Apalindrome is a string that is identical to its reversed form, e. g., the word "tenet" is a palindrome, and so is the sentence "name no one man", if you ignore the blank spaces. outline a recursive procedure to check whether a given string of characters (assume that all whitespace characters such as blank spaces and punctuations have been already removed) is a palindrome or not. hint: recall the recursive procedure to reverse a string of characters, that was shown in class. however, don't simply use that procedure to first reverse a string and then compare with the original string to detect a palindrome. this latter procedure would require 2 separate string variables (the second holds the reversed string), but you should solve the problem without using any extra string variable.
