数据结构中的基本问题-the basic question in data structure.

约瑟夫环 已知n个人（以编号1，2，3...n分别表示）围坐在一张圆桌周围。从编号为k的人开始报数，数到m的那个人出列；他的下一个人又从1开始报数，数到m的那个人又出列；依此规律重复下去，直到圆桌周围的人全部出列。（有详细注解）数据结构学习的好例子-Joseph ring known n individuals (identified by serial number 1,2,3 ... n, respectively) were sitting around on a round-table. K from the number of people reported a few, a few of the m out of that person him from one of the next person to start off, a few m to another person out and so the law of repetition until around round-table All of the people out. (Detailed notes) data structure to learn a good example of
