Check Palindrome Strings

Problem Description:

You are given a string s, and your task is to determine whether it is a palindrome. A palindrome is a sequence that reads the same backward as forward after removing all non-alphanumeric characters and ignoring letter case. In other words, the string should be processed to remove punctuation and spaces, and then compared to its reverse.

For example, the string A man, a plan, a canal: Panama is a palindrome, whereas race a car is not.

The solution should read input from standard input (stdin) and output the result to standard output (stdout) as either True or False.

outputFormat

Output Description:

Output a single line with either True if the given string is a palindrome (considering only alphanumeric characters and ignoring cases) or False otherwise.## sample
