Description

abstract public Ds\Sequence::rotate(int $rotations): void

Rotates the sequence by a given number of rotations, which is equivalent to successively calling $sequence->push($sequence->shift()) if the number of rotations is positive, or $sequence->unshift($sequence->pop()) if negative.

Parameters

rotations

The number of times the sequence should be rotated.

Return Values

No value is returned.. The sequence of the current instance will be rotated.

Examples

Example #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);
?>

The above example will output something similar to:

(
    [0] => b
    [1] => c
    [2] => d
    [3] => a
)
