本程序采用循环单链表的算法来解决约瑟夫环问题：建立一个循环单链表，按顺序查找指定结点，找到后删除，最后打印删除的编号序列。- This procedure uses circulates Shan Lianbiao algorithm to solve
the Joseph link problem: Establishes to circulate Shan Lianbiao,
assigns the point according to the smooth search, after found deletes,
finally prints the serial number sequence which deletes.
