The input has to be on the stack as a string, in the specified format (example: '7A UA DA').

In case the input is valid, the program prints the total value of the cards.

In case there's at least one duplicate card, the program throws the following exception:

undefined method `each' for 0:Fixnum (NoMethodError)
