Hence, the binary tree structure expands downward vertically as nodes are added. To visualize a binary tree, you can imagine it as an inverted tree where the root node is at the top and the branches ...

Binary Tree: Each node has a maximum of two children.; Binary Search Tree (BST): A binary tree where each node's left subtree has values less than the node and the right subtree has values greater.

Binary Search Trees. Given a binary tree, suppose we visit each node (recursively) as follows. We visit left child, then root and then the right child. For example, visiting the following tree . In ...
