</ul>
|
||||
<p>当使用数组实现列表时，<strong>长度不可变的性质会导致列表的实用性降低</strong>。这是因为我们通常无法事先确定需要存储多少数据，从而难以选择合适的列表长度。若长度过小，则很可能无法满足使用需求；若长度过大，则会造成内存空间的浪费。</p>
|
||||
<p>为解决此问题，我们可以使用「动态数组 dynamic array」来实现列表。它继承了数组的各项优点，并且可以在程序运行过程中进行动态扩容。</p>
|
||||
<p>实际上，<strong>许多编程语言中的标准库提供的列表都是基于动态数组实现的</strong>，例如 Python 中的 <code>list</code> 、Java 中的 <code>ArrayList</code> 、C++ 中的 <code>vector</code> 和 C# 中的 <code>List</code> 等。在接下来的讨论中，我们将把“列表”和“动态数组”视为等同的概念。</p>

<p>许多编程语言内置了列表，例如 Java、C++、Python 等。它们的实现比较复杂，各个参数的设定也非常考究，例如初始容量、扩容倍数等。感兴趣的读者可以查阅源码进行学习。</p>
|
||||
<p>为了加深对列表工作原理的理解，我们尝试实现一个简易版列表，包括以下三个重点设计。</p>
|
||||
<ul>
|
||||
<li><strong>初始容量</strong>：选取一个合理的数组初始容量。在本示例中，我们选择 10 作为初始容量。</li>
|
||||
<li><strong>数量记录</strong>：声明一个变量 <code>size</code> ，用于记录列表当前元素数量，并随着元素插入和删除实时更新。根据此变量，我们可以定位列表尾部，以及判断是否需要扩容。</li>
|
||||
<li><strong>扩容机制</strong>：若插入元素时列表容量已满，则需要进行扩容。首先根据扩容倍数创建一个更大的数组，再将当前数组的所有元素依次移动至新数组。在本示例中，我们规定每次将数组扩容至之前的 2 倍。</li>
