<p>「哈希查找 Hash Searching」借助一个哈希表来存储需要的「键值对 Key Value Pair」，我们可以在 <span class="arithmatex">\(O(1)\)</span> 时间下实现“键 <span class="arithmatex">\(\rightarrow\)</span> 值”映射查找，体现着“以空间换时间”的算法思想。</p>

<p>如果我们想要给定数组中的一个目标元素 <code>target</code> ，获取该元素的索引，那么可以借助一个哈希表实现查找。</p>

<p>再比如，如果我们想要给定一个目标结点值 <code>target</code> ，获取对应的链表结点对象，那么也可以使用哈希查找实现。</p>

<p>「线性查找 Linear Search」是一种最基础的查找方法，其从数据结构的一端开始，依次访问每个元素，直到另一端后停止。</p>
<h2 id="1011">10.1.1. &nbsp; 算法实现<a class="headerlink" href="#1011" title="Permanent link">&para;</a></h2>
<p>线性查找实质上就是遍历数据结构 + 判断条件。比如，我们想要在数组 <code>nums</code> 中查找目标元素 <code>target</code> 的对应索引，那么可以在数组中进行线性查找。</p>
