The unit tests are provided in test.py. Modify func.py to implement the function rather than submit it in text.\n\nCURRENT SETUP:\n- func.py: Contains the function signature you need to implement\n- test.py: Contains the test cases that your implementation must pass\n\nTOOLS AVAILABLE:\n- bash: Execute shell commands (e.g., run tests with `python test.py`)\n- python: Execute Python code for debugging\n- text_editor: Edit files\n- 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.\n\nWORKFLOW:\n1. First, examine func.py to understand the function signature\n2. Look at test.py to understand what the function should do\n3. Implement the function **in func.py**\n4. Run `python test.py` to check if your implementation passes\n5. If tests fail, analyze the error and iterate\n\nYou can submit up to 3 times and will receive feedback after each attempt.\n\nRemember:\n- Focus on implementing the function correctly in func.py\n- The tests in test.py should not be modified\n- Run `python test.py` to validate your solution\n",
