- // Return true if the given string is a palindrome. Otherwise,
- // return false.
- // A palindrome is a word or sentence that's spelled the same
- // way both forward and backward, ignoring punctuation, case,
- // and spacing.
- // Note
- // You'll need to remove all non-alphanumeric characters (punctuation,
- // spaces and symbols) and turn everything into the same case
- // (lower or upper case) in order to check for palindromes.
- // We'll pass strings with varying formats, such as "racecar",
- // "RaceCar", and "race CAR" among others.
- // We'll also pass strings with special symbols, such as "2A3*3a2",
- // "2A3 3a2", and "2_A3*3#A2".
