A palindrome is a sentence that contains the same sequence of letters reading it either forwards or backwards. For example "racecar". Write a recursive function that detects whether a string is a palindrome. The basic idea is to check that the first and last letters of the string are the same letter. If they are, then the entire string is a palindrome if everything between those letters is a palindrome. When you compare letters, ensure you do it in a case-insensitive way. Use your function in a program that prompts the user for a phrase and then tells whether or not it is a palindrome.
