Recently, a few friends and I spent about an hour solving a computer science puzzle that was posed to us, indirectly, by Facebook’s AI-powered Messenger Assistant, M. Rather than explain our findings immediately, I’m going to tell the story of our investigation as it unfolded, so you can think along with us and come up with your own hypothesis along the way. In my opinion, puzzling through this problem is a great computer science thought exercise.

In a group chat on Facebook Messenger, a group of poker buddies from undergrad (read: mainly computer science and math majors) were talking about Jeff Bezos and his insane net worth. One of them jokingly asked for a hundred billion dollars, and M immediately tried to play wingman.
