< p > 「插入排序 Insertion Sort」是一种基于数组插入操作的排序算法。具体来说， < code > base< / code > ，将 < code > base< / code > 与其左侧已排序区间的元素逐一比较大小，并将其插入到正确的位置。< / p >
< p > 回顾数组插入操作，我们需要将从目标索引到 < code > base< / code > 之间的所有元素向右移动一位，然后再将 < code > base< / code > 赋值给目标索引。< / p >

< p > 插入排序的整体流程如下：< / p >
< ol >
< li > 首先，选取数组的第 2 个元素作为 < code > base< / code > ，执行插入操作后，< strong > 数组的前 2 个元素已排序< / strong > 。< / li >
< li > 接着，选取第 3 个元素作为 < code > base< / code > ，执行插入操作后，< strong > 数组的前 3 个元素已排序< / strong > 。< / li >
< li > 以此类推，在最后一轮中，选取数组尾元素作为 < code > base< / code > ，执行插入操作后，< strong > 所有元素均已排序< / strong > 。< / li >

< h2 id = "1133" > 11.3.3. 插入排序优势< a class = "headerlink" href = "#1133" title = "Permanent link" > ¶ < / a > < / h2 >
< p > 回顾冒泡排序和插入排序的复杂度分析，两者的循环轮数都是 < span class = "arithmatex" > \(\frac{(n - 1) n}{2}\)< / span > 。然而，它们之间存在以下差异：< / p >
< ul >
< li > 冒泡操作基于元素交换实现，需要借助一个临时变量，共涉及 3 个单元操作；< / li >
< li > 插入操作基于元素赋值实现，仅需 1 个单元操作；< / li >
< / ul >
< p > 粗略估计下来，冒泡排序的计算开销约为插入排序的 3 倍，因此插入排序更受欢迎。实际上，许多编程语言（如 Java） ， ： < / p >
< ul >
< li > 对于长数组，采用基于分治的排序算法，例如「快速排序」，时间复杂度为 < span class = "arithmatex" > \(O(n \log n)\)< / span > ； < / li >
< li > 对于短数组，直接使用「插入排序」，时间复杂度为 < span class = "arithmatex" > \(O(n^2)\)< / span > ； < / li >
< / ul >
< p > 尽管插入排序的时间复杂度高于快速排序，< strong > 但在数据量较小的情况下，插入排序实际上更快< / strong > 。这是因为在数据量较小时，复杂度中的常数项（即每轮中的单元操作数量）起主导作用。这个现象与「线性查找」和「二分查找」的情况相似。< / p >
