Running Time of Algorithms

    Here's my PHP solution:

    function runningTime($arr) {
    // Write your code here
    $total = 0;
    
    for ($i=0; $i < count($arr)-1; $i++) {
        $temp = 0;
        for ($j=$i+1; $j < count($arr); $j++) {
            if ($arr[$j] < $arr[$i]) {
                $temp = $arr[$j];
                // delete array $arr[$j]
                unset($arr[$j]);
                
                // insert in front of array
                array_splice( $arr, $i, 0, $temp );
                
                // count step
                $total = $total + ($j - $i);
                
                // re-index array
                $arr = array_values($arr);
            }
        }
    } 
    return $total;
}
