Code Kata: the card game of war

The card game of war is a very old, but still popular game. I used to play it when I was a child. The game is very suitable for small kids, because it has simple rules and the players don't need to make any decisions - it's enough to follow the rules. In this article, we will try to go through the process of modeling the game of war as a computer program. And as we will see later, the modeling may have some very practical uses. Let's start.

The game is usually played with 24 cards of four colors. The cards are as follows, next to each card there is a single letter that will represent the card for us.

• Ace - A
• King - K
• Queen - Q
• Jack - J
• 10 - T
• 9 - N

The colors do not matter in the basic version of the game. The 24 cards are distributed randomly between two players. Each player starts with 12 cards. The player who loses all the cards loses the game. Main steps of the game will be executed by the function:
