<p>「空间复杂度 Space Complexity」用于衡量算法占用内存空间随着数据量变大时的增长趋势。这个概念与时间复杂度非常类似，只需将“运行时间”替换为“占用内存空间”。</p>

<h2 id="231">2.3.1. 算法相关空间<a class="headerlink" href="#231" title="Permanent link">¶</a></h2>
|

<p>算法运行过程中使用的内存空间主要包括以下几种：</p>
|
||||
<ul>
|
||||
<li>「输入空间」用于存储算法的输入数据。</li>
|
||||
<li>「暂存空间」用于存储算法运行过程中的变量、对象、函数上下文等数据。</li>
|
||||
<li>「输出空间」用于存储算法的输出数据。</li>
|
||||
<li><strong>输入空间</strong>：用于存储算法的输入数据。</li>
|
||||
<li><strong>暂存空间</strong>：用于存储算法运行过程中的变量、对象、函数上下文等数据。</li>
|
||||
<li><strong>输出空间</strong>：用于存储算法的输出数据。</li>
|
||||
</ul>
|
||||
<p>通常情况下，空间复杂度统计范围是「暂存空间」+「输出空间」。</p>
|
||||
<p>一般情况下，空间复杂度的统计范围是“暂存空间”加上“输出空间”。</p>
|
||||
<p>暂存空间可以进一步划分为三个部分：</p>
|
||||
<ul>
|
||||
<li>「暂存数据」用于保存算法运行过程中的各种常量、变量、对象等。</li>
|
||||
<li>「栈帧空间」用于保存调用函数的上下文数据。系统在每次调用函数时都会在栈顶部创建一个栈帧，函数返回后，栈帧空间会被释放。</li>
|
||||
<li>「指令空间」用于保存编译后的程序指令，在实际统计中通常忽略不计。</li>

<h2 id="232">2.3.2. 推算方法<a class="headerlink" href="#232" title="Permanent link">¶</a></h2>
|
||||
<p>空间复杂度的推算方法与时间复杂度大致相同，只是将统计对象从“计算操作数量”转为“使用空间大小”。与时间复杂度不同的是，<strong>我们通常只关注「最差空间复杂度」</strong>，这是因为内存空间是一项硬性要求，我们必须确保在所有输入数据下都有足够的内存空间预留。</p>
|
||||
<p><strong>最差空间复杂度中的“最差”有两层含义</strong>，分别是输入数据的最差分布和算法运行过程中的最差时间点。</p>
|
||||
<ul>
|
||||
<li><strong>以最差输入数据为准</strong>。当 <span class="arithmatex">\(n < 10\)</span> 时，空间复杂度为 <span class="arithmatex">\(O(1)\)</span> ；但当 <span class="arithmatex">\(n > 10\)</span> 时，初始化的数组 <code>nums</code> 占用 <span class="arithmatex">\(O(n)\)</span> 空间；因此最差空间复杂度为 <span class="arithmatex">\(O(n)\)</span> 。</li>
|
||||
<li><strong>以算法运行过程中的峰值内存为准</strong>。例如，程序在执行最后一行之前，占用 <span class="arithmatex">\(O(1)\)</span> 空间；当初始化数组 <code>nums</code> 时，程序占用 <span class="arithmatex">\(O(n)\)</span> 空间；因此最差空间复杂度为 <span class="arithmatex">\(O(n)\)</span> 。</li>
