Test description

A palindrome is a sequence of characters—such as a word, phrase, number, or other sequence—that reads the same forward as backward, disregarding spaces, punctuation, and capitalization. In other words, it maintains its original sequence when read in reverse. Classic examples of palindromes include words like "radar" and "level," phrases such as "A man, a plan, a canal, Panama!" and numerical sequences like "1221." Palindromes are often celebrated for their inherent symmetry and play a role in linguistic puzzles and wordplay.
