<p><strong>例二：整理扑克</strong>。我们在打斗地主时，每局都需要整理扑克牌，使其从小到大排列，实现流程如下：</p>
|
||||||
|
<ol>
|
||||||
|
<li>将扑克牌划分为“有序”和“无序”两部分，并假设初始状态下最左 1 张扑克牌已经有序。</li>
|
||||||
|
<li>在无序区间抽出一张扑克牌，插入至有序区间的正确位置；完成后最左 2 张扑克已经有序。</li>
|
||||||
|
<li>在无序区间抽出一张扑克牌，插入至有序区间的正确位置；完成后最左 3 张扑克已经有序。</li>
|
||||||
|
<li>不断循环以上操作，直至所有扑克牌都有序后终止。</li>
|
||||||
|
</ol>
|
||||||
|
<p>以上整理扑克牌的方法本质上就是「插入排序」，它在处理小型数据集时非常高效，因此插入排序常作为编程语言的排序库函数的重要组成部分。</p>
