合并数组

“合并数组”问题的详细指南和 Python 实现。

问题陈述

简单

编写一个函数 merge_sorted_arrays(arr1, arr2) ,它接受两个排序整数数组 arr1arr2 ,并将它们合并为一个排序数组,然后返回该数组。

约束条件
  • 0 <= len(arr1), len(arr2) <= 10^4
  • -10^9 <= arr1[i], arr2[j] <= 10^9

示例

Example 1
Input
arr1 = [1, 3, 5], arr2 = [2, 4, 6]
Output
[1, 2, 3, 4, 5, 6]
Explanation

We merge elements from both arrays sequentially preserving the sorted order.

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
