Binary Search Tree (BST) & Traversal Laboratory
Nodes: 7|Search: O(log N)
Standard Depth-First Tree Traversals
Inorder (L → Root → R)Always Sorted!
[20, 30, 40, 50, 60, 70, 80]
Preorder (Root → L → R)
[50, 30, 20, 40, 70, 60, 80]
Postorder (L → R → Root)
[20, 40, 30, 60, 80, 70, 50]
Invariant Property:
For any node N in a Binary Search Tree, all keys in the left subtree satisfy key < N.val, and all keys in the right subtree satisfy key > N.val. This property guarantees that an Inorder Traversal produces strictly sorted elements in O(N) time!
