Uno (Part 2)

This problem is a continuation of Uno Part 1 (although you don't need to complete that problem to complete this one).

It's your turn to play again. Create a function that takes as its arguments (1) your hand (an array of cards), and (2) the face-up card. In Uno, you are able to play a card from your hand if either:

• One of the card colors in your hand matches the face-up card's color.
• One of the card numbers in your hand matches the face-up card's number.

Write a function that will return:

1. "Uno!" if after playing your card, you are left with a single card.
2. "You won!" if after playing your card, you are left with zero cards (an empty array).
3. "Keep going..." otherwise.

Examples

decision(["yellow 3", "red 3"], "red 10") ➞ "Uno!"

decision(["blue 1"], "blue 5") ➞ "You won!"

decision(["blue 1", "green 2", "yellow 4", "red 2"], "blue 5") ➞ "Keep going..."
