选择排序

“选择排序”问题的详细指南和 Python 实现。

问题陈述

简单

编写一个函数 selection_sort(arr),使用选择排序算法按升序对整数列表 arr 进行排序,并返回排序后的列表。

约束条件
  • 0 <= len(arr) <= 500
  • -10^4 <= arr[i] <= 10^4

示例

Example 1
Input
arr = [64, 25, 12, 22, 11]
Output
[11, 12, 22, 25, 64]
Explanation

We repeatedly find the minimum element from the unsorted part and swap it with the beginning.

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
