Returns a sorted copy

public Ds\Vector::sorted ([ callable $comparator ] ) : Ds\Vector

Returns a sorted copy, using an optional comparator function.

comparator: �ڵ�һ��С�ڣ��ڻ��ڵڶ��ʱ��ñȽϺ��Ӧ�ط��һ��С�ڣ��ڻ�� 0 ��

callback ( mixed $a, mixed $b ) : int

Caution
Returning non-integer values from the comparison function, such as float, will result in an internal cast to integer of the callback's return value. So values such as 0.99 and 0.1 will both be cast to an integer value of 0, which will compare such values as equal.

Returns a sorted copy of the vector.

$sorted = $vector->sorted(function($a, $b) {
    return $b <=> $a;
