選擇排序

“選擇排序”問題的詳細指南和 Python 實作。

問題陳述

簡單

寫一個函數 selection_sort(arr),使用選擇排序演算法依升序對整數列表 arr 進行排序,並傳回排序後的列表。

約束條件
  • 0 <= len(arr) <= 500
  • -10^4 <= arr[i] <= 10^4

範例

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?
考慮使用特定於排序的資料結構,例如集合或堆。
Edge Cases to Watch
  • 空輸入結構
  • 單元素輸入
  • 大數值範圍
