A palindrome is a word, phrase, number, or other sequence of characters that reads the same forward and backward. Some examples of palindromic words are "level," "racecar," and "deified." Some palindromic phrases are "A man, a plan, a canal: Panama," and "Madam In Eden, I'm Adam." Palindromes can also be numeric sequences, such as "12321" and "9,121." The concept of palindromes can be found in many different areas, including mathematics, linguistics, and literature.
