Recursion: Palindrome Phrase A palindrome is a series of letters or numbers that reads equivocally backwards. Write a recursive function that determines whether a given string is a palindrome or not. Examples is_palindrome ("Go hang a salami, I'm a lasagna hog!") + True is_palindrome ("This phrase, surely, is not a palindrome!") False is_palindrome ("Eva, can I see bees in a cave?") + True Notes . Symbols and special characters should be ignored. You are expected to solve this challenge via recursion.
