function getMaxElement($array)
{
    $n = count($array);
    $max = $array[0];
    for ($i = 1;$i < $n;$i++) if ($max < $array[$i]) $max = $array[$i];
    return $max;
}

// Find maximum in array
function getMinElement($array)
{
    $n = count($array);
    $min = $array[0];
    for ($i = 1;$i < $n;$i++) if ($min > $array[$i]) $min = $array[$i];
