Create and parameterize an array

The Scala Array is a mutable collection that stores a fixed-size sequential collection of elements of the same type.

In the context of Twenty-One, an array is a good choice to represent something that can change, like the particular players playing (their names specifically). Something else that changes: the specific hands in each round.

In this exercise, you'll create and parameterize an array for the first round of Twenty-One with three players (i.e., each player has one hand in this round). Note: you won't initialize the array with data yet!
