Palindrome Checker

A palindrome is a word, phrase, number, or sequence of characters that reads the same backward as it does forward. In other words, it remains the same even when its order is reversed. Palindromes can be formed by letters, numbers, or a combination of both. For example, “racecar,” “madam,” and “level” are all palindromic words. Similarly, the number 1221 and the phrase “Able was I ere I saw Elba” are palindromes. Palindromes often provide a sense of symmetry and can be an interesting linguistic or mathematical phenomenon.
