Adding CLAUDE.md with task information for AI processing. This file will be removed when the task is complete. Issue: #85
This commit addresses issue #85 by implementing the optimal performance solution for checking child existence flags in AVL tree nodes. Performance improvements: - Replaced UncheckedConverter approach with direct bit manipulation - Achieved ~4-5x performance improvement (from ~71μs to ~17μs) - Direct bit operations: ((value >> N) & One) != Zero Changes: - Updated GetLeftIsChildValue() and GetRightIsChildValue() methods - Added comprehensive benchmarks comparing all approaches - Maintained backward compatibility - all tests pass - Added detailed performance analysis documentation The direct bit manipulation approach outperformed: 1. UncheckedConverter (previous): ~71μs → ~17μs 2. EqualityComparer approaches: ~91-98μs 3. Unchecked variants showed minimal benefit 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
