(Hint: You cannot use the system already has functions, please also carefully recall the basic knowledge previously learned)
Quick_sort ($left _arr); $right _arr = $this->quick_sort ($right _arr); Return Array_merge ($left _arr, Array ($key), $right _arr); }/** * Hill sort */Public function Shell_sort ($datas) {//Group for ($increment = count ($data s)/2; $increment > 0; $increment = $increment/2) {//Sort within each group for ($i = $increment; $i < count ($datas); $i + +) { $temp = $datas [$i]; $j = 0; for ($j = $i; $j >= $increment; $j = $j-$increment) {if ($temp < $datas [$j-$increment]) {$datas [$j] = $datas [$j-$increment]; } else {break; }} $datas [$j] = $temp; }} return $datas; }}?>
