將數組的元素進行排序

「對陣列元素進行排序」問題的詳細指南和 Python 實作。

問題陳述

簡單

寫一個函數 sort_array(arr) ,它接受整數列表 arr 並傳回一個新列表,其中所有元素均按升序排序。

約束條件
  • 0 <= len(arr) <= 10^5
  • -10^9 <= arr[i] <= 10^9

範例

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?
考慮使用特定於數組的資料結構,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
