Ds\Deque::rotate — Rotates the deque by a given number of rotations
Rotates the deque by a given number of rotations, which is equivalent
to successively calling $deque->push($deque->shift())
if the number
of rotations is positive, or $deque->unshift($deque->pop())
if negative.
rotations
The number of times the deque should be rotated.
Es wird kein Wert zurückgegeben.. The deque of the current instance will be rotated.
Beispiel #1 Ds\Deque::rotate() example
<?php
$deque = new \Ds\Deque(["a", "b", "c", "d"]);
$deque->rotate(1); // "a" is shifted, then pushed.
print_r($deque);
$deque->rotate(2); // "b" and "c" are both shifted, the pushed.
print_r($deque);
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
( [0] => b [1] => c [2] => d [3] => a ) Ds\Deque Object ( [0] => d [1] => a [2] => b [3] => c )
