Binary Search Trees (BST) & Tree Traversals

Insert, search, and delete BST nodes in O(log N) average time, and master In-order, Pre-order, and Post-order Depth-First Search traversals.

Binary Search Tree Invariants

### BST Invariants A Binary Search Tree is a hierarchical node structure where for every node: - All values in its **left subtree** are strictly LESS than the node's value. - All values in its **right subtree** are strictly GREATER than the node's value.
