2：有n个人围成一圈,顺序排号.从第一个人开始报数（从1到3报数）,凡报到3的人退出圈子,

扩展为：从1至N开始顺序循环数数,每数到M输出该数值,直至全部输出
链表实现：
#include
#include
typedef struct Node
{
int index;
struct Node *next;
}JosephuNode;
int Josephu(int n,int m)
{
int i,j;
JosephuNode *head,*tail;
head = tail = (JosephuNode *)malloc(sizeof(JosephuNode));
for (i = 1; i < n; ++i)
{
tail->index = i;
tail->next = (JosephuNode *)malloc(sizeof(JosephuNode));
tail = tail->next;
}
tail->index = i;
tail->next = head;
for (i = 1; tail != head; ++i)
{
for (j = 1; j < m; ++j)
{
tail = head;
head = head->next;
}
tail->next = head->next;
printf("第%4d个出局的人是：%4d号\n",i,head->index);
free(head);
head = tail->next;
}
i = head->index;
free(head);
return i;
}
int main()
{
int n,m;
scanf("%d%d",&n,&m);
printf("最后胜利的是%d号!\n",Josephu(n,m));
system("pause");
return 0;
}
