In the childrensgamehotpotato,agroupofnchildrensitinacirclepassingan object, called the potato, around the circle (say in a clockwise direction). The children continue passing the potato until a leader rings a bell, at which point the child holding the potato must leave the game, and the other children close up the circle. This process is then continued until there is only one child remaining, who is declared the winner. Using a list, describe an efficient method for imple- menting this game. Suppose the leader always rings the bell immediately after the potato has been passed k times. (Determining the last child remaining in this variation of hot potato is known as the Josephus problem.) What is the running time of your method in terms of n and k, assuming the list is implemented with a doubly linked list? What if the list is implemented with an array?
