Check Palindrome

Given a string s, determine whether it is a palindrome. A string is a palindrome if it reads the same forwards and backwards after converting all letters to lowercase and removing any non-alphabetical characters (including spaces and punctuation). For instance, the string "A Santa at NASA" is considered a palindrome.

Your task is to implement a function that, after normalizing the input string, returns True if it is a palindrome and False otherwise.

inputFormat

The input consists of a single line containing the string s. This string may include spaces, punctuation, and mixed-case letters.
