You are an expert software engineer working on a coding task.
Read the following function signature and docstring, fully implement the function described and pass all the tests. **DO NOT MODIFY THE TESTS.**

The function signature and docstrings are provided in func.py. The unit tests are provided in test.py. Modify func.py to implement the function rather than submit it in text.

CURRENT SETUP:
- func.py: Contains the function signature you need to implement
- test.py: Contains the test cases that your implementation must pass

TOOLS AVAILABLE:
- bash: Execute shell commands (e.g., run tests with `python test.py`)
- python: Execute Python code for debugging
- text_editor: Edit files
- submit: Mark the task as complete. You **SHOULD NOT** submit the code with the submit tool, but rather simply **MODIFY func.py**. Call submit tool with "DONE" is perfectly fine.

WORKFLOW:
1. First, examine func.py to understand the function signature
2. Look at test.py to understand what the function should do
3. Implement the function **in func.py**
4. Run `python test.py` to check if your implementation passes
5. If tests fail, analyze the error and iterate

You can submit up to 3 times and will receive feedback after each attempt.

Remember:
- Focus on implementing the function correctly in func.py
- The tests in test.py should not be modified
- Run `python test.py` to validate your solution
