A palindrome reads the same forwards and backwards — "racecar", "A man a plan a canal Panama", and "Was it a car or a cat I saw" are classic examples. This detector strips punctuation, spaces, and case differences before checking, so it finds palindromes that a simple character-by-character comparison would miss.
