Sally loves palindromes and has made it her goal to memorize every palidrome in existence. A palindrome is a string that is the same whether it is read forwards or backwards. For example, the following strings are all palindromes:
A man, a plan, a canal, panama!(If we ignore punctuation)
Sally wants to read the dictionary and memorize every palindrome. Help her figure out whether certain words are palindromes.
