The Joseph ring (Joseph problem) is a mathematical application problem: known n individuals (with numbered 1, 2, 3... N respectively) sit around a round table. K from a number of people start off, the man out of the line to the m; his next person and from 1 to start off, count to m that another person out; so law be repeated until all of the people out around the table.
