Example

use Frowhy\Algorithm\Algorithm;

require_once __DIR__ . '/vendor/autoload.php';

$total = 20;
$arr   = [];
for ($i = 0; $i < $total; $i++) {
    $arr[] = rand(-10000, 10000);
}

$quickSort     = Algorithm::quickSort($arr);
$bubbleSort    = Algorithm::bubbleSort($arr);
$selectionSort = Algorithm::selectionSort($arr);
$insertionSort = Algorithm::insertionSort($arr);
$shellSort     = Algorithm::shellSort($arr);
$mergeSort     = Algorithm::mergeSort($arr);
$countingSort  = Algorithm::countingSort($arr);
$heapSort      = Algorithm::heapSort($arr);

print_r([
            '原数组'  => $arr,
            '快速排序' => $quickSort,
