You can change me
Let's test out a prototype one-player version of Twenty-One. Your friend Alex is playerA. They are dealt two cards: the jack of clubs (J♣) and the ace of diamonds (A♦). They know the default implementation of the game has aces worth 1 point but they want it to be worth 11 so they can add their two cards together to get 21.
In this exercise, you'll code up this scenario. jackClubs (a val with a point value of 10) and aceDiamonds (a var with a point value of 1) are already defined.
