Study Notes
Binary Search Tree Characteristics
- Each node entry in a Binary Search Tree has a unique key.
- All keys in the left subtree of a node are less than (not greater than) the key of the node.
Traversal Methods
- In an Inorder traversal, the parent node is visited after traversing the left subtree and before traversing the right subtree.
- In a Postorder traversal, the parent node is visited after traversing both the left and right subtrees.
Binary Tree Characteristics
- A Binary Tree is a type of tree where each node typically has at most two children (i.e., a left child and a right child).
