PHP实现冒泡算法
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);?>
