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