### This is example of the script that will be run in the test environment.
### Some parts of the code are compulsory and you should NOT CHANGE THEM.
### They are between '''---compulsory---''' comments.
### You can change the rest of the code to define and test your solution.
### However, you should not change the signature of the provided function.
### The script would save "submission.parquet" file in the current directory.
### The actual logic of the solution is implemented in the `handcrafted_solution.py` file.
### The `handcrafted_solution.py` file is a placeholder for your solution.
### You should implement the logic of your solution in that file.
### You can use any additional files and subdirectories to organize your code.
