Pull request overview
This PR addresses a Python version compatibility issue by replacing the bit_count() method (Python 3.10+) with a backward-compatible alternative that works with older Python versions.
- Replaces
int.bit_count()withbin(int).count('1')to count set bits - Ensures the challenge code runs on Python versions older than 3.10
- Maintains functional equivalence while improving compatibility
