< h1 id = "51" > 5.1 堆疊< a class = "headerlink" href = "#51" title = "Permanent link" > ¶ < / a > < / h1 >
< p > < u > 堆疊（ ） < / u > 是一種遵循先入後出邏輯的線性資料結構。< / p >
< p > 我們可以將堆疊類比為桌面上的一疊盤子，如果想取出底部的盤子，則需要先將上面的盤子依次移走。我們將盤子替換為各種型別的元素（如整數、字元、物件等），就得到了堆疊這種資料結構。< / p >
< p > 如圖 5-1 所示，我們把堆積疊元素的頂部稱為“堆疊頂”，底部稱為“堆疊底”。將把元素新增到堆疊頂的操作叫作“入堆疊”，刪除堆疊頂元素的操作叫作“出堆疊”。< / p >

< h2 id = "511" > 5.1.1 堆疊的常用操作< a class = "headerlink" href = "#511" title = "Permanent link" > ¶ < / a > < / h2 >
< p > 堆疊的常用操作如表 5-1 所示，具體的方法名需要根據所使用的程式語言來確定。在此，我們以常見的 < code > push()< / code > 、< code > pop()< / code > 、< code > peek()< / code > 命名為例。< / p >

< p > 通常情況下，我們可以直接使用程式語言內建的堆疊類別。然而，某些語言可能沒有專門提供堆疊類別，這時我們可以將該語言的“陣列”或“鏈結串列”當作堆疊來使用，並在程式邏輯上忽略與堆疊無關的操作。< / p >

< p > 為了深入瞭解堆疊的執行機制，我們來嘗試自己實現一個堆疊類別。< / p >
< p > 堆疊遵循先入後出的原則，因此我們只能在堆疊頂新增或刪除元素。然而，陣列和鏈結串列都可以在任意位置新增和刪除元素，< strong > 因此堆疊可以視為一種受限制的陣列或鏈結串列< / strong > 。換句話說，我們可以“遮蔽”陣列或鏈結串列的部分無關操作，使其對外表現的邏輯符合堆疊的特性。< / p >
< h3 id = "1" > 1. 基於鏈結串列的實現< a class = "headerlink" href = "#1" title = "Permanent link" > ¶ < / a > < / h3 >
< p > 使用鏈結串列實現堆疊時，我們可以將鏈結串列的頭節點視為堆疊頂，尾節點視為堆疊底。< / p >
< p > 如圖 5-2 所示，對於入堆疊操作，我們只需將元素插入鏈結串列頭部，這種節點插入方法被稱為“頭插法”。而對於出堆疊操作，只需將頭節點從鏈結串列中刪除即可。< / p >

< h2 id = "513" > 5.1.3 兩種實現對比< a class = "headerlink" href = "#513" title = "Permanent link" > ¶ < / a > < / h2 >
< p > < strong > 支持操作< / strong > < / p >
< p > 兩種實現都支持堆疊定義中的各項操作。陣列實現額外支持隨機訪問，但這已超出了堆疊的定義範疇，因此一般不會用到。< / p >
< p > < strong > 時間效率< / strong > < / p >
< p > 在基於陣列的實現中，入堆疊和出堆疊操作都在預先分配好的連續記憶體中進行，具有很好的快取本地性，因此效率較高。然而，如果入堆疊時超出陣列容量，會觸發擴容機制，導致該次入堆疊操作的時間複雜度變為 < span class = "arithmatex" > \(O(n)\)< / span > 。< / p >
< p > 在基於鏈結串列的實現中，鏈結串列的擴容非常靈活，不存在上述陣列擴容時效率降低的問題。但是，入堆疊操作需要初始化節點物件並修改指標，因此效率相對較低。不過，如果入堆疊元素本身就是節點物件，那麼可以省去初始化步驟，從而提高效率。< / p >
< p > 綜上所述，當入堆疊與出堆疊操作的元素是基本資料型別時，例如 < code > int< / code > 或 < code > double< / code > ，我們可以得出以下結論。< / p >
< ul >
< li > 基於陣列實現的堆疊在觸發擴容時效率會降低，但由於擴容是低頻操作，因此平均效率更高。< / li >
< li > 基於鏈結串列實現的堆疊可以提供更加穩定的效率表現。< / li >
< / ul >
< p > < strong > 空間效率< / strong > < / p >
< p > 在初始化串列時，系統會為串列分配“初始容量”，該容量可能超出實際需求；並且，擴容機制通常是按照特定倍率（例如 2 倍）進行擴容的，擴容後的容量也可能超出實際需求。因此，< strong > 基於陣列實現的堆疊可能造成一定的空間浪費< / strong > 。< / p >
< p > 然而，由於鏈結串列節點需要額外儲存指標，< strong > 因此鏈結串列節點佔用的空間相對較大< / strong > 。< / p >
< p > 綜上，我們不能簡單地確定哪種實現更加節省記憶體，需要針對具體情況進行分析。< / p >
< h2 id = "514" > 5.1.4 堆疊的典型應用< a class = "headerlink" href = "#514" title = "Permanent link" > ¶ < / a > < / h2 >
< ul >
< li > < strong > 瀏覽器中的後退與前進、軟體中的撤銷與反撤銷< / strong > 。每當我們開啟新的網頁，瀏覽器就會對上一個網頁執行入堆疊，這樣我們就可以通過後退操作回到上一個網頁。後退操作實際上是在執行出堆疊。如果要同時支持後退和前進，那麼需要兩個堆疊來配合實現。< / li >
< li > < strong > 程式記憶體管理< / strong > 。每次呼叫函式時，系統都會在堆疊頂新增一個堆疊幀，用於記錄函式的上下文資訊。在遞迴函式中，向下遞推階段會不斷執行入堆疊操作，而向上回溯階段則會不斷執行出堆疊操作。< / li >
