<p>To implement a queue, we need a data structure that allows adding elements at one end and removing elements at the other end. Both linked lists and arrays meet this requirement.</p>
<h3 id="1-linked-list-implementation">1. &nbsp; Linked List Implementation<a class="headerlink" href="#1-linked-list-implementation" title="Permanent link">&para;</a></h3>
<p>As shown in Figure 5-5, we can treat the "head node" and "tail node" of a linked list as the "front" and "rear" of the queue, respectively, with the rule that nodes can only be added at the rear and removed from the front.</p>

<li>Dequeue operation: Simply increase <code>front</code> by 1 and decrease <code>size</code> by 1.</li>
</ul>
<p>As you can see, both enqueue and dequeue operations require only one operation, with a time complexity of <span class="arithmatex">\(O(1)\)</span>.</p>
