 ## Part 2:  Calculating a Score
 
-You will write a method called:  `blackjack_score` which take an array of card values and returns the blackjack score.  The card values can be any of the following, number values 1-9, "King", "Queen", "Jack".  If the array contains an invalid card value or the total exceeds 21, raise an `ArgumentError`.  For example `blackjack_score([1, 5, 3])` will return 19.  You should also raise an error if the hand contains more than 5 cards.

The card values can be any of the following, number values 2-9, "King", "Queen", "Jack", "Ace".  If the array contains an invalid card value or the total exceeds 21, raise an `ArgumentError`.  For example `blackjack_score(["Ace", 5, 3])` will return 19.  You should also raise an error if the hand contains more than 5 cards.
 
 In this exercise you will complete the given tests in `test/blackjack_score_test.rb` and updating the `blackjack_score` method in `lib/blackjack_score.rb` to make it pass.
