Challenge

In the game of OddCards, only the odd-valued cards count. Each hand of cards is worth the sum of the odd-valued cards. However, multiples of 3 are deadly! If you get a card that is odd and is a multiple of 3 you lose all your points and the hand is scored at 0.

You will be given an array cards that contains the integer values of a hand of cards. Write a method that returns the score of cards.
