<h1 id="112">11.2. &nbsp; 选择排序<a class="headerlink" href="#112" title="Permanent link">&para;</a></h1>
<p>「选择排序 Selection Sort」的工作原理非常直接：开启一个循环，每轮从未排序区间选择最小的元素，将其放到已排序区间的末尾。</p>
<p>选择排序的算法流程如下：</p>
<p>设数组的长度为 <span class="arithmatex">\(n\)</span> ，选择排序的算法流程如下：</p>
<ol>
<li>初始状态下，所有元素未排序，即未排序（索引）区间为 <span class="arithmatex">\([0, n-1]\)</span> 。</li>
<li>选取区间 <span class="arithmatex">\([0, n-1]\)</span> 中的最小元素，将其与索引 <span class="arithmatex">\(0\)</span> 处元素交换。完成后，数组前 1 个元素已排序。</li>
