<?php
$deque = new \Ds\Deque(['a', 'b', 'c', 1, 2, 3]);

var_dump($deque->contains('a'));                // true
var_dump($deque->contains('a', 'b'));           // true
var_dump($deque->contains('c', 'd'));           // false

var_dump($deque->contains(...['c', 'b', 'a'])); // true

// Always strict
var_dump($deque->contains(1));                  // true
var_dump($deque->contains('1'));                // false

var_dump($sequece->contains(...[]));               // true
?>
