/*Explanation of solution

blackJackCS is a map with the key value being that of myhand on the blackjack cheat sheet, the val value is an array.

The dealers hand is represented by the position in the array, for example, dealer hand of 2 is represented by positin 2 in the array

the array is of length 11, and holds the suggested solution to the current hand set

With this solution only one call is preformed after user input, everything is mapped and ready
