< p > 最直接的方法是借助“元素入堆操作”实现，首先创建一个空堆，然后将列表元素依次添加到堆中。< / p >
< p > 设元素数量为 < span class = "arithmatex" > \(n\)< / span > ，则最后一个元素入堆的时间复杂度为 < span class = "arithmatex" > \(O(\log n)\)< / span > 。在依次添加元素时，堆的平均长度为 < span class = "arithmatex" > \(\frac{n}{2}\)< / span > ，因此该方法的总体时间复杂度为 < span class = "arithmatex" > \(O(n \log n)\)< / span > 。< / p >

< p > 接下来我们来进行更为详细的计算。为了减小计算难度，我们假设树是一个“完美二叉树”，该假设不会影响计算结果的正确性。设二叉树（即堆）节点数量为 < span class = "arithmatex" > \(n\)< / span > ，树高度为 < span class = "arithmatex" > \(h\)< / span > 。上文提到，< strong > 节点堆化最大迭代次数等于该节点到叶节点的距离，而该距离正是“节点高度”< / strong > 。< / p >
