<h1 id="43">4.3 串列<a class="headerlink" href="#43" title="Permanent link">¶</a></h1>
|
||
<p><u>串列（list）</u>是一個抽象的資料結構概念，它表示元素的有序集合，支持元素訪問、修改、新增、刪除和走訪等操作，無須使用者考慮容量限制的問題。串列可以基於鏈結串列或陣列實現。</p>
|
||
<ul>
|
||
<li>鏈結串列天然可以看作一個串列，其支持元素增刪查改操作，並且可以靈活動態擴容。</li>
|
||
<li>陣列也支持元素增刪查改，但由於其長度不可變，因此只能看作一個具有長度限制的串列。</li>
|
||
</ul>
|
||
<p>當使用陣列實現串列時，<strong>長度不可變的性質會導致串列的實用性降低</strong>。這是因為我們通常無法事先確定需要儲存多少資料，從而難以選擇合適的串列長度。若長度過小，則很可能無法滿足使用需求；若長度過大，則會造成記憶體空間浪費。</p>
|
||
<p>為解決此問題，我們可以使用<u>動態陣列（dynamic array）</u>來實現串列。它繼承了陣列的各項優點，並且可以在程式執行過程中進行動態擴容。</p>
|
||
<p>實際上，<strong>許多程式語言中的標準庫提供的串列是基於動態陣列實現的</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。在接下來的討論中，我們將把“串列”和“動態陣列”視為等同的概念。</p>

<h3 id="3">3. 插入與刪除元素<a class="headerlink" href="#3" title="Permanent link">¶</a></h3>
|

<p>相較於陣列，串列可以自由地新增與刪除元素。在串列尾部新增元素的時間複雜度為 <span class="arithmatex">\(O(1)\)</span> ，但插入和刪除元素的效率仍與陣列相同，時間複雜度為 <span class="arithmatex">\(O(n)\)</span> 。</p>

<h2 id="432">4.3.2 串列實現<a class="headerlink" href="#432" title="Permanent link">¶</a></h2>
|
||
<p>許多程式語言內建了串列，例如 Java、C++、Python 等。它們的實現比較複雜，各個參數的設定也非常考究，例如初始容量、擴容倍數等。感興趣的讀者可以查閱原始碼進行學習。</p>
|
||
<p>為了加深對串列工作原理的理解，我們嘗試實現一個簡易版串列，包括以下三個重點設計。</p>
|
||
<ul>
|
||
<li><strong>初始容量</strong>：選取一個合理的陣列初始容量。在本示例中，我們選擇 10 作為初始容量。</li>
|
||
<li><strong>數量記錄</strong>：宣告一個變數 <code>size</code> ，用於記錄串列當前元素數量，並隨著元素插入和刪除實時更新。根據此變數，我們可以定位串列尾部，以及判斷是否需要擴容。</li>
|
||
<li><strong>擴容機制</strong>：若插入元素時串列容量已滿，則需要進行擴容。先根據擴容倍數建立一個更大的陣列，再將當前陣列的所有元素依次移動至新陣列。在本示例中，我們規定每次將陣列擴容至之前的 2 倍。</li>
|
||
</ul>
