对数组的元素进行排序

“对数组元素进行排序”问题的详细指南和 Python 实现。

问题陈述

简单

编写一个函数 sort_array(arr) ,它接受整数列表 arr 并返回一个新列表,其中所有元素均按升序排序。

约束条件
  • 0 <= len(arr) <= 10^5
  • -10^9 <= arr[i] <= 10^9

示例

Example 1
Input
arr = [5, 2, 8, 1, 9]
Output
[1, 2, 5, 8, 9]
Explanation

Elements rearranged from smallest to largest.

Example 2
Input
arr = [3, -1, 4, -1, 5]
Output
[-1, -1, 3, 4, 5]
Explanation

Negative numbers come first, duplicates are kept.

Example 3
Input
arr = [1]
Output
[1]
Explanation

Single element is already sorted.

Need a Hint?
考虑使用特定于数组的数据结构,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
