Pull Request Overview
This pull request implements two key features: a run-length encoder and a fix for a thread-safety issue in the ID generator.
- Implement run-length encoding (RLE) in python/rle.py
- Fix thread-safety in next_id() by introducing a lock in buggy_counter.py
- Update documentation in SOLUTIONS.md to reflect changes and the approach taken

- [nitpick] Consider reviewing the necessity of time.sleep(0) inside the lock. If it is not required for yielding control, removing it might improve performance.
time.sleep(0)
| This approach is optimal of performance and simple. It achieves O(n) time complexity by processing the string in one pass. | ||
