| # Q: How to pass state in a DAG | |
| # A: We got variables already. EventOperation could take a variable as well! | |
| # Q: How to pass state between DAGs? | |
| # A: Use event payload. | |

Design a program to determine the winner of a poker game.
The order of a card would be described as "23456789TJQKA", the suit of a card would be described as "HSCD" (Heart, Spade, Club, Diamond). Each card would be presented by two characters, i.e. "9D", "KC" etc.
You would be given a list of hands as a text file, each line represents a
