A group of monkeys in a circle, according to 1,2,...,n sequentially numbered. And then, starting with the 1th, count to the number of M, and kick It out of the loop.

A group of monkeys in a circle, according to 1,2,...,n sequentially numbered. Then, starting from the 1th, Count to M., Kick It Out of the loop, start counting from behind it, Count to M., and Kick It out ... and so on, until the last monkey is left, the monkey is called the King. Requires programming to simulate this process, enter m, N, output the last king's number

<?php

$n the number of monkeys $m the first few places

function fn ($n, $m)
{

Put the number of monkeys in the array
for ($i = 1; $i < $n +1; $i + +) {
$arr [] = $i;
}
$i = 0;
Var_dump ($i);

When only one value is left in the array to jump out of the array
while (count ($arr) > 1) {
echo $i. " \ n ";
if (($i + 1)% $m = = 0) {

When the number of cycles satisfies the M value to remove the current value
Unset ($arr [$i]);
}else{

Do not meet the number of loops put into the array to the tail
Array_push ($arr, $arr [$i]);

Delete Current loop contents
Unset ($arr [$i]);
}
