Palindrome Checker
Check whether a word or phrase is a palindrome, ignoring spaces, punctuation, and capitalization.
Yes, that's a palindrome!
Ignores spaces, punctuation, and capitalization — "A man, a plan, a canal: Panama" counts as a palindrome because it reads the same forwards and backwards once you strip those out.
Example input
A man, a plan, a canal: Panama
Example output
Yes, that's a palindrome!
