堆排序

“堆排序”问题的详细指南和 Python 实现。

问题陈述

简单

编写一个函数 heap_sort(arr),使用堆排序算法(首先构建最大堆)按升序对整数列表 arr 进行排序,并返回排序后的列表。

约束条件
  • 0 <= len(arr) <= 10^4
  • -10^5 <= arr[i] <= 10^5

示例

Example 1
Input
arr = [12, 11, 13, 5, 6, 7]
Output
[5, 6, 7, 11, 12, 13]
Explanation

A max heap is created, the maximum element is repeatedly swapped with the last element of the heap, and heapify is performed.

Need a Hint?
考虑使用特定于排序的数据结构,例如集合或堆。
Edge Cases to Watch
  • 空输入结构
  • 单元素输入
  • 大数值范围
