<h1 id="61">6.1. 哈希表<a class="headerlink" href="#61" title="Permanent link">¶</a></h1>
|
|
|
<p>哈希表通过建立「键 key」与「值 value」之间的映射，实现高效的元素查询。具体而言，我们向哈希表输入一个 key，则可以在 <span class="arithmatex">\(O(1)\)</span> 时间内获取对应的 value 。</p>
|
|
|
<p>以一个包含 <span class="arithmatex">\(n\)</span> 个学生的数据库为例，每个学生都有“姓名 <code>name</code>”和“学号 <code>id</code>”两项数据。假如我们希望实现查询功能，例如“输入一个学号，返回对应的姓名”，则可以采用哈希表来实现。</p>

<h2 id="611">6.1.1. 哈希表效率<a class="headerlink" href="#611" title="Permanent link">¶</a></h2>
|
|
|
<p>除哈希表外，还可以使用以下数据结构来实现上述查询功能：</p>
|
|
|
<ol>
|
|
|
<li><strong>无序数组</strong>：每个元素为 <code>[学号, 姓名]</code> ；</li>
|
|
|
<li><strong>有序数组</strong>：将 <code>1.</code> 中的数组按照学号从小到大排序；</li>
|
|
|
<li><strong>链表</strong>：每个节点的值为 <code>[学号, 姓名]</code> ；</li>
|
|
|
<li><strong>二叉搜索树</strong>：每个节点的值为 <code>[学号, 姓名]</code> ，根据学号大小来构建树；</li>
|
|
|
</ol>
|
|
|
<p>各项操作的时间复杂度如下表所示（详解可见<a href="https://www.hello-algo.com/chapter_tree/binary_search_tree/">二叉搜索树章节</a>）。无论是查找元素还是增删元素，哈希表的时间复杂度都是 <span class="arithmatex">\(O(1)\)</span> ，全面胜出！</p>

<h2 id="613">6.1.3. 哈希函数<a class="headerlink" href="#613" title="Permanent link">¶</a></h2>
|
|
|
<p>哈希表的底层实现为数组，同时可能包含链表、二叉树（红黑树）等数据结构，以提高查询性能（将在下节讨论）。</p>
|
|
|
<p>首先考虑最简单的情况，<strong>仅使用一个数组来实现哈希表</strong>。通常，我们将数组中的每个空位称为「桶 Bucket」，用于存储键值对。</p>
|
|
|
<p>我们将键值对 key, value 封装成一个类 <code>Entry</code> ，并将所有 <code>Entry</code> 放入数组中。这样，数组中的每个 <code>Entry</code> 都具有唯一的索引。为了建立 key 和索引之间的映射关系，我们需要使用「哈希函数 Hash Function」。</p>
|
|
|
<p>设哈希表的数组为 <code>buckets</code> ，哈希函数为 <code>f(x)</code> ，那么查询操作的步骤如下：</p>
|
|
|
<ol>
|
|
|
<li>输入 <code>key</code> ，通过哈希函数计算出索引 <code>index</code> ，即 <code>index = f(key)</code> ；</li>
|
|
|
<li>通过索引在数组中访问到键值对 <code>entry</code> ，即 <code>entry = buckets[index]</code> ，然后从 <code>entry</code> 中获取对应的 <code>value</code> ；</li>
|
|
|
</ol>
|
|
|
<p>以学生数据 <code>key 学号 -> value 姓名</code> 为例，我们可以设计如下哈希函数：</p>
|
|
|
<div class="arithmatex">\[
|
|
|
f(x) = x \% 100
|
|
|
\]</div>

<h2 id="614">6.1.4. 哈希冲突<a class="headerlink" href="#614" title="Permanent link">¶</a></h2>
|
|
|
<p>细心的你可能已经注意到，<strong>在某些情况下，哈希函数 <span class="arithmatex">\(f(x) = x % 100\)</span> 可能无法正常工作</strong>。具体来说，当输入的 key 后两位相同时，哈希函数的计算结果也会相同，从而指向同一个 value 。例如，查询学号为 <span class="arithmatex">\(12836\)</span> 和 <span class="arithmatex">\(20336\)</span> 的两个学生时，我们得到：</p>
|
|
|
<div class="arithmatex">\[
|
|
|
f(12836) = f(20336) = 36
|
|
|
\]</div>
|
|
|
<p>这两个学号指向了同一个姓名，这显然是错误的。我们把这种情况称为「哈希冲突 Hash Collision」。在后续章节中，我们将讨论如何解决哈希冲突的问题。</p>

|
|
|
<p align="center"> Fig. 哈希冲突示例 </p>
|
|
|
|
|
|
<p>综上所述，一个优秀的哈希函数应具备以下特性：</p>
|
|
|
<ul>
|
|
|
<li>尽可能减少哈希冲突的发生；</li>
|
|
|
<li>查询效率高且稳定，能够在绝大多数情况下达到 <span class="arithmatex">\(O(1)\)</span> 时间复杂度；</li>
|
|
|
<li>较高的空间利用率，即使“键值对占用空间 / 哈希表总占用空间”比例最大化；</li>
|
|
|
</ul>
