<h2 id="812">8.1.2. 堆常用操作<a class="headerlink" href="#812" title="Permanent link">¶</a></h2>
|
||||
<p>值得说明的是，多数编程语言提供的是「优先队列 Priority Queue」，其是一种抽象数据结构，<strong>定义为具有出队优先级的队列</strong>。</p>
|
||||
<p>而恰好，<strong>堆的定义与优先队列的操作逻辑完全吻合</strong>，大顶堆就是一个元素从大到小出队的优先队列。从使用角度看，我们可以将「优先队列」和「堆」理解为等价的数据结构。因此，本文与代码对两者不做特别区分，统一使用「堆」来命名。</p>
|
||||
<p>堆的常用操作见下表（方法命名以 Java 为例）。</p>
|
||||
<p>堆的常用操作见下表，方法名需根据编程语言确定。</p>
