本演示程序演算约瑟夫环问题，人数n应为任意的，首先应输入一个值赋给初始报数上限m，程序应能自动保存出列人的序号和将出列的人所持的密码赋给m，再次作为报数上限，如此循环，直至所有人都出列为止。-The demo program Joseph Central calculus problem, the number n should be arbitrary, we must first enter a value assigned to the initial reported that the maximum number of m, the procedure should be able to automatically save a list of the serial number of people and held out the password given to m, again as reported maximum number of such cycles, until all that far out.
