Problem: Blackjack

Create a function named `blackJack()` that accepts two parameters:
playerCardScore (number)
dealerCardScore (number)

Return whichever value is nearest (or equal) to 21 without going over. Return 0 if both scores go over 21.

Test Cases:
Use the following test cases to confirm your program meets the success criteria

1. blackJack(19, 21)

   Result: 21

2. blackJack(22, 22)

   Result: 0

3. blackJack(19, 22)

   Result: 19

3. blackJack(21, 21)

/***********
Problem: Word Counter

Create a function named `wordCount()` that accepts a parameter called "phrase" which counts the number of occurrences of each word in that phrase

For example, the phrase: "olly olly in come free" should result in output that looks similar to the following:

```
olly: 1
in: 1
come: 1
free: 1
```

Feel free to add any additional functions or variables you deem necessary to meet the above requirements

Test Cases:
Use the following test cases to confirm your program meets the success criteria

1. wordCount("olly olly in come free")

   Result:

   olly: 2
   in: 1
   come: 1
   free: 1

2. wordCount("Baby shark, doo doo doo doo doo doo")

   Result:

   baby: 1
   shark: 1
   doo: 6


3. wordCount("Humpty Dumpty sat on a wall Humpty Dumpty had a great fall")

   Result:

   humpty: 2
   dumpty: 2
   sat: 1
   a: 2
   on: 1
   fall: 1
   great: 1
   had: 1

/***********
Problem: Scrabble Scorer

Create a function named `scrabbleScore()` that accepts a parameter called "word". The function should use the following table to calculate the Scrabble score of a provided word:

```
Letter                           Value
A, E, I, O, U, L, N, R, S, T       1
D, G                               2

Q, Z                               10
```

Feel free to add any additional functions or variables you deem necessary to meet the above requirements

Test Cases:
Use the following test cases to confirm your program meets the success criteria

1. scrabbleScore("cabbage")
   Note: c = 3, a = 1 (twice), b = 3 (twice), g = 2, e = 1

   Expected Result: 14
