The coffee shop puzzle is a variation of a classic computer science problem. Don’t mention which one here to keep it interesting. ;D Some people can think through the problem and solve it in seconds. Others will remain baffled for hours. Ideally, work out a strategy in your mind and carefully execute it. Don’t rely on paper and certainly don’t code up a program to solve for you. Post a screen shot if you’re the first to solve it. Good luck!
