这篇文章主要介绍了php实现约瑟夫问题的方法,实例总结了两种常见的实现约瑟夫问题的技巧,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例总结了php实现约瑟夫问题的方法。分享给大家供大家参考。具体分析如下:

一群猴子排成一圈,按1,2,...,n依次编号。然后从第1只开始数,数到第m只,把它踢出圈,从它后面再开始数, 再数到第m只,在把它踢出去...,如此不停的进行下去, 直到最后只剩下一只猴子为止,那只猴子就叫做大王。要求编程模拟此过程,输入m、n, 输出最后那个大王的编号。

解析:

约瑟夫环是一个数学的应用问题: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。

方法一:

方法二:

编号为'.$monkeys[0].'的猴子成为猴王了!'; return; }else{ while($num++ "; array_splice($monkeys , $current , 1); getKing($monkeys , $m , $current); } } $n=13; //总共猴子数目 $m = 34; //数到第几只的那只猴子被踢出去 $monkeys = range(1,$n); //将猴子编号放入数组中 getKing($monkeys , $m); //调用函数 ?>

希望本文所述对大家的php程序设计有所帮助。
