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 <stdio.h>
#include <malloc.h>
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;
