说明：  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，每个人有一个密码。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，数到上一个人的密码的数的那个人又出列；依此规律重复下去，直到圆桌周围的人全部出列。

From the number of people began to report the number of k, the number of the person out to m column his newspaper the next person and from a start number, the number to a person' s password on the number of the person and the column and so the law repeated until the round table around all the columns.)
