/*

Deck is a class that emulates a card deck with the numbers 1-10

and the colors Red and Black.

Deck.ToString should return the cards in their current order "R1 R2 R3 B1 B4 B6 R8..."

​

A new Deck() should be in order "R1 R2 ... B1 B2 ..."

Deck.Shuffle should randomly mix up the cards.

​

Modify to code so that the test passes.

​

Implement Shuffle.

​

Create more unit tests to fully cover this application.

​

Modify the code to contain player class, which can contain cards like Deck

PlayerHand should sort cards when shuffle is called.

​

Modify the Deck to add a method Draw() which removes and returns the top card

​

With time remaining improve the application for readability, abstraction, or object-oriented principles
