Frequently Asked Questions
?What is a binary search tree?
A tree data structure where each node's left children are smaller and right children are larger.
?What traversal orders are supported?
In-order (sorted), pre-order (root first), and post-order (root last).
?Can I delete nodes?
Yes, enter a value and click Delete. The tree restructures automatically.
?What happens with duplicate values?
