Example #1 Ds\Deque::insert() example
<?php
$deque = new \Ds\Deque();
$deque->insert(0, "e"); // [e]
$deque->insert(1, "f"); // [e, f]
$deque->insert(2, "g"); // [e, f, g]
$deque->insert(0, "a", "b"); // [a, b, e, f, g]
$deque->insert(2, ...["c", "d"]); // [a, b, c, d, e, f, g]
var_dump($deque);

The above example will output something similar to:
object(Ds\Deque)#1 (7) { [0]=> string(1) "a" [1]=> string(1) "b" [2]=> string(1) "c" [3]=> string(1) "d" [4]=> string(1) "e" [5]=> string(1) "f" [6]=> string(1) "g" }
