  ###############################################
  # A palindrome is a word or a phrase that reads 
  # the same backwards as forwards. Make a program 
  # that checks if a word is a palindrome. 
  # If the word is a palindrome, print 0 to the terminal,
  # -1 otherwise. 
  # The word contains lowercase letters a-z and 
  # will be at least one character long.
  #
  ### HINT! ###
  # You can read a string backwards with the following syntax:
  # string[::-1] - where the "-1" means one step back.
  # This exercise can be solved with only unit 1 knowledge
  # (no loops or conditions)
  
  word = "madam"
  # test case 2
  #word = "madman" # uncomment this to test
  
  ###
  # YOUR CODE HERE. DO NOT DELETE THIS LINE OR ADD A word DEFINITION BELOW IT.
  ###
  
  is_palindrome = -1 + (word[::1] == word[::-1])
  
  # TESTING
  print is_palindrome
  #print word[::-1]
  # >>> 0  # outcome if word == "madam"
  # >>> -1 # outcome if word == "madman"
subject: add isPalindrome without loops or conditions
