Check Palindrome (Ignoring Case and Punctuation)

Given a string s, determine whether it is a palindrome by ignoring spaces, punctuation, and case differences. A palindrome is a string that reads the same backward as forward. For example, A man, a plan, a canal, Panama should be considered a palindrome.

You need to read the input from standard input (stdin) and output the result to standard output (stdout). The output should be either True or False based on whether the string is a palindrome.

The check must filter out non-alphanumeric characters and treat uppercase and lowercase letters as equivalent.

inputFormat

The input consists of a single line containing a string s (possibly containing spaces and punctuation).

outputFormat

Output a single line: True if the input string is a palindrome based on the given criteria, or False otherwise.

A man, a plan, a canal, Panama

True
