The circular queue – Hot Potato

As queues are often applied in computer science and also in our lives, there are some modified versions of the default queue we implemented in this chapter. One of the modified versions is the circular queue.

At a certain point of the game, the hot potato stops being passed around the circle of children, and the child that has the hot potato is removed from the circle. This action is repeated until there is only one child left (the winner).
