# Blackjack

# first, we have a deck of 52 cards (how to organize data?)
#   - suits value worth 10
#   - aces value worth 11 or 1

# dealer is dealt 2 cards at random
# player is dealt 2 cards at 

# player goes: choose hit or stay
#   - if hit, dealt another card (until stay)
#     - take sum of cards
#       - if sum more than 21, player bust
#   - if stay, take total sum of cards

# dealer goes: choose hit or stay
#   - if sum of cards <= 17, hit
#   - if sum more than 21, dealer bust
#   - else stay

# - compare sum of player and dealer
