#编号1到n的n个猴子围成一圈,从k号猴子开始从1报数,k+1号猴子报2,k+2号猴子报3........ 报到m就出局 剩下的重新从1报数,报到m出局,反复循环, 求最后剩下的那只猴子的编号。
function myf($array,$m,$n,$k){
    $mark=0;
    $a=$m;
    $m=$m+$k-1;

    while(sizeof($array)){
    	$mark++;
    	$out=array_shift($array);
        if($mark==$m){
        	if(sizeof($array)==0){
        	echo $out , '最终留下<br/>';
        	}else{
                    $m=$a;
        	    echo $out , '出局<br/>';
        	    $mark=0;


        	}
        }else{
         $array[]=$out;
        }


    }


}

myf(range(1, 5),3,5,2);#测试一下,编号1到5的猴子,从2号开始由1报数,报到3的出局
