Binary Tree Traversal
Advanced
Implement in-order, pre-order, and post-order traversal. Implement efficiently for production-grade data structures and algorithms.
Constraints
- Optimize for time and space complexity
- Handle edge cases (empty inputs, single elements)
- Consider cache locality and real-world performance
Hints
Hint 1
Think about the fundamental structure: is it a search, sort, dynamic programming, or graph problem?
Hint 2
Identify the bottleneck: what operation repeats most often?
