. A band of 10 pirates are going to disband. They have divided up all of their gold, but there
remains one GIANT diamond that cannot be divided. To decide who gets it the captain puts all of
the pirates (including himself) in a circle. Then he points at one person to begin. This person
steps out of the circle, takes his gold, and leaves. The person on his left stays in the circle, but
the next person steps out. This continues with every second pirate leaving until there is only one
left. Who should the captain point at if he wants to make sure he gets to keep the diamond for
himself?
