堆排序(Heap Sort)是利用堆这种数据结构而设计的一种排序算法,是一种选择排序。 堆是具有以下性质的完全二叉树:每个结点的值都大于或等于其左右孩子结点的值,称为大顶堆;或者每个结点的值都小于或等于其左右孩子结点的值,称为小顶堆。 堆排序思路为: 将一个无序序列调整为一个堆,就能找出序列中的最大值(或...
python实现【堆排序】(HeapSort) 算法原理及介绍 堆排序(Heapsort)是指利用堆这种数据结构所设计的一种排序算法*。堆实质是一个近似完全二叉树的结构*,并同时满足堆积的性质:即子结点的键值或索引总是小于(或者大于)它的父节点。堆排序可以说是一种利用堆的概念来排序的选择排序。
