Примеры
Пример #1 Ds\Vector::rotate() example
<?php
$vector = new \Ds\Vector(["a", "b", "c", "d"]);
$vector->rotate(1); // "a" is shifted, then pushed.
print_r($vector);
$vector->rotate(2); // "b" and "c" are both shifted, the pushed.
print_r($vector);
?>
Результатом выполнения данного примера будет что-то подобное:
