<p>内存空间是所有程序的公共资源，排除已被占用的内存空间，空闲内存空间通常散落在内存各处。在上一节中，我们提到存储数组的内存空间必须是连续的，而当我们需要申请一个非常大的数组时，空闲内存中可能没有这么大的连续空间。与数组相比，链表更具灵活性，它可以被存储在非连续的内存空间中。</p>
|
||
<p>「链表 Linked List」是一种线性数据结构，其每个元素都是一个节点对象，各个节点之间通过指针连接，从当前节点通过指针可以访问到下一个节点。<strong>由于指针记录了下个节点的内存地址，因此无需保证内存地址的连续性</strong>，从而可以将各个节点分散存储在内存各处。</p>
|
||
<p>链表「节点 Node」包含两项数据，一是节点「值 Value」，二是指向下一节点的「指针 Pointer」，或称「引用 Reference」。</p>

<p class="admonition-title">尾节点指向什么？</p>
|
||
<p>我们将链表的最后一个节点称为「尾节点」，其指向的是“空”，在 Java, C++, Python 中分别记为 <span class="arithmatex">\(\text{null}\)</span> , <span class="arithmatex">\(\text{nullptr}\)</span> , <span class="arithmatex">\(\text{None}\)</span> 。在不引起歧义的前提下，本书都使用 <span class="arithmatex">\(\text{null}\)</span> 来表示空。</p>

<div class="admonition question">
|
||
<p class="admonition-title">如何称呼链表？</p>
|
||
<p>在编程语言中，数组整体就是一个变量，例如数组 <code>nums</code> ，包含各个元素 <code>nums[0]</code> , <code>nums[1]</code> 等等。而链表是由多个节点对象组成，我们通常将头节点当作链表的代称，例如头节点 <code>head</code> 和链表 <code>head</code> 实际上是同义的。</p>
|
||
</div>
|
||
<p><strong>链表初始化方法</strong>。建立链表分为两步，第一步是初始化各个节点对象，第二步是构建引用指向关系。完成后，即可以从链表的头节点（即首个节点）出发，通过指针 <code>next</code> 依次访问所有节点。</p>

<p><strong>链表中插入与删除节点的操作效率高</strong>。例如，如果我们想在链表中间的两个节点 <code>A</code> , <code>B</code> 之间插入一个新节点 <code>P</code> ，我们只需要改变两个节点指针即可，时间复杂度为 <span class="arithmatex">\(O(1)\)</span> ；相比之下，数组的插入操作效率要低得多。</p>

<p>在链表中删除节点也非常方便，只需改变一个节点的指针即可。如下图所示，尽管在删除操作完成后，节点 <code>P</code> 仍然指向 <code>n1</code> ，但实际上 <code>P</code> 已经不再属于此链表，因为遍历此链表时无法访问到 <code>P</code> 。</p>

<h2 id="422">4.2.2. 链表缺点<a class="headerlink" href="#422" title="Permanent link">¶</a></h2>
|
||
<p><strong>链表访问节点效率较低</strong>。如上节所述，数组可以在 <span class="arithmatex">\(O(1)\)</span> 时间下访问任意元素。然而，链表无法直接访问任意节点，这是因为系统需要从头节点出发，逐个向后遍历直至找到目标节点。例如，若要访问链表索引为 <code>index</code>（即第 <code>index + 1</code> 个）的节点，则需要向后遍历 <code>index</code> 轮。</p>

<h2 id="424">4.2.4. 常见链表类型<a class="headerlink" href="#424" title="Permanent link">¶</a></h2>
|
||
<p><strong>单向链表</strong>。即上述介绍的普通链表。单向链表的节点包含值和指向下一节点的指针（引用）两项数据。我们将首个节点称为头节点，将最后一个节点成为尾节点，尾节点指向 <span class="arithmatex">\(\text{null}\)</span> 。</p>
|
||
<p><strong>环形链表</strong>。如果我们令单向链表的尾节点指向头节点（即首尾相接），则得到一个环形链表。在环形链表中，任意节点都可以视作头节点。</p>
|
||
<p><strong>双向链表</strong>。与单向链表相比，双向链表记录了两个方向的指针（引用）。双向链表的节点定义同时包含指向后继节点（下一节点）和前驱节点（上一节点）的指针。相较于单向链表，双向链表更具灵活性，可以朝两个方向遍历链表，但相应地也需要占用更多的内存空间。</p>
