思想很简单，就是一个循环链表 但要说明的是：我之所以用clist(1)来初始化，主要是我刚开始编的时候没打算解决约瑟夫环，只是想编一个带表头的循环链表，然后我用从这个程序改过来的，所以代码可以进一步优化。-Thinking is very simple, that is, a cycle list but would like to note is: I use clist (1) to initialize, mainly because I had just started when Joseph did not intend to resolve the ring, just want to provision a table with the head circulation list, and then I used to come from this process, so the code can be further optimized.
