Implement a function in Python that takes in two sorted arrays of integers and merges them into a single sorted array without using any built-in sorting functions. What data structure would you use for this implementation and what would be the time complexity of your solution?

To implement a function in Python that merges two sorted arrays of integers without using any built-in sorting functions, we can use the following code snippet:

```python
def merge_sorted_arrays(arr1, arr2):
merged_arr = []
i = 0
j = 0
while i < len(arr1) and j < len(arr2): if arr1[i] < arr2[j]: merged_arr.append(arr1[i]) i += 1 else: merged_arr.append(arr2[j]) j += 1 merged_arr.extend(arr1[i:]) merged_arr.extend(arr2[j:]) return merged_arr ```For this implementation, we will use the data structure of a list to merge the two sorted arrays into a single sorted array. The time complexity of this solution is O(m + n), where m and n are the lengths of the input arrays.By employing this efficient solution for merging sorted arrays in Python, you can seamlessly handle the task without relying on any built-in sorting functions.
