Pull Request: Add Comments to Merge Sort Code

Description:

This pull request adds comments to the existing merge sort implementation to improve code readability and maintainability. Comments provide a better understanding of the code's functionality and structure.

Changes Made:

• Added comments to explain the purpose of the merge_sort function.
• Included comments for the key steps within the merge_sort function, such as splitting the array and merging two halves.
• Documented the usage of variables and loops within the code.

Example Usage:

# Example usage:
my_list = [12, 11, 13, 5, 6, 7]
merge_sort(my_list)
print(my_list)

Testing:

Tested the code with various input arrays to ensure correctness and stability.

Related Issues:

• Closes (create merge sort code #723)

Additional Notes:

Feel free to review and provide feedback on the code. It should make the merge sort implementation more understandable for future contributors and maintainers.

One minor suggestion is to consider adding a brief description of the merge sort algorithm itself, either in the function docstring or as a comment at the top of the file. This would provide context for readers who may not be familiar with the algorithm.
Additionally, some of the variable names could be more descriptive. For example, instead of my_list, consider using unsorted_list or input_array to make it clearer what the variable represents.
