Hey there - I've reviewed your changes - here's some feedback:
- In the Python solution, consider adding a standard LeetCode Solution class wrapper and type hints (e.g. List[int]) to align with typical submission formats.
- You could simplify Gray code generation by directly computing each entry with
i ^ (i >> 1)instead of using the reflection loop for a more concise implementation. - The Markdown explanation is very thorough, but the "Brute force vs. optimized strategy" section feels a bit verbose—consider trimming it to focus more on the reflection method.
