WebHeapSort is a comparison-based sorting technique where we first build Max Heap and then swap the root element with the last element (size times) and maintains the heap property each time to finally make it sorted.

Web本文介绍另一种排序算法，即heap sort，其具有以下特点： 与合并排序类似，堆排序运行时间为 O (n\lg n) ，快于插入排序 与插入排序类似，堆排序为in-place排序算法，在任何时候，数组中只有常熟个元素存储在输入数组以外 因此heap sort将 merge sort的速度快和插入排序的in place特点结合起来。 堆排序还引入了另一种算法设计技术，即利用某种数据结构 … WebHeapify takes an array that represents a binary tree of the sort mentioned and rearranges so it satisfies the heap property. Heapsort then repeated removes the minimum value (at index 0) and fixes up the heap (which is a simpler version of heapify). As the values are removed, they are done in sorted order.
