This month, Using your Head is Permitted is teaming up again with IBM's
Ponder This. See the
Ponder This December challenge for a riddle related to this one.
Every Christmas, the employees of MegaCorp play a gift-giving lottery game. On the first of December, each of the company's N employees picks a number between 1 and N out of a hat (the same hat) to be their unique ID number in the game. On Christmas day, each employee sends a gift to the person who has the highest ID number among all employees who are directly connected to them on LinkedIn. We consider every employee to be connected to herself, so if every one of an employee's connections has a lower ID number than herself, that employee will be sending a self-addressed Christmas present.
Note that in a valid graph of LinkedIn connections, for any i and j, if i is connected to j then j is connected to i.
