# 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.

# You'll need to remove punctuation and turn everything lower case in order

# to check for palindromes.

# We'll pass strings with varying formats, such as "racecar", "RaceCar",

# and "race CAR" among others.
