我发现很多公司面试的时候都会出一道冒泡算法的题,这么基础的算法,一般程序员应该都写得出来,但是今天我在网上看了一下,发现很多文章中的冒泡算法都是错的,根本就不是冒泡算法!还堂而皇之的说什么解析冒泡算法,真是误导新人啊。我就直接上代码了,这,才是冒泡算法。


<?phpfunction bubbleSort($ary){	$len = count($ary);	for ($i=0; $i < $len - 1; $i++) { 		for ($j=0; $j < $len - 1 -$i; $j++) { 			if ($ary[$j] > $ary[$j + 1]) {				$tmp = $ary[$j];				$ary[$j] = $ary[$j + 1];				$ary[$j + 1] = $tmp;			}		}	}	return $ary;}$ary = [1,6,789,3,56,8,1234,45];$newAry = bubbleSort($ary);print_r($newAry);?>
