The next method in the Cards module will be contains? method. That checks wether the list has a specific element, return either true or false.
By convention, whenever function has a question mark in it ? it will return a boolean value.
To check whether a card is in the deck we can use the Enum.member? method.
def contains?(deck, card) do
Enum.member?(deck, card)
end
