15)A troop is surrounded by the enemy, they need help and there is only one
horse to call reinforcement. To decide who will ride the horse and go to
fetch reinforcements they play a game? solve this problem using a circular
linked list, implement the following function.
struct Node*whoRidesHorse(struct Node*circular List Head,unsigned int count)
{
*
shall return the last remained soldier from the list
shall return the last remained soldier from the list
*
}
