Program must be written in C++:

A palindrome is any word, phrase, or sentence that reads the same forward and backward. Here are some well-known palindromes:

Able was I, ere I saw Elba

A man, a plan, a canal, Panama

Desserts, I stressed

Kayak

Write a bool function isPalindrome that uses recursion to determine if a string argument is a palindrome. The function should return true if the argument reads the same forward and backward. You may test your function using the palindromes listed above.
