Point taken. I guess /some/ commentary really is necessary.
I've been hooked on the Kindle Blackjack game. So I wrote
this program to help me improve my guesses.
The program (initially and after each 's'huffle) maintains
the number of each rank of card contained in 4 standard
playing card decks. '0' means "10" on input and output.
The 'prompt' is a table showing the number of each card,
the number of "tens", the total number of cards left in
the shoe, and the integer percentages for each card and
for "tens".
So when any cards are played, type them in and hit enter.
This will show what's left in the deck after every hand.
