Solution: Inorder Successor in BST

Explore how to identify the inorder successor of a given node in a binary search tree by applying depth-first search techniques. This lesson teaches you to use BST properties to traverse the tree effectively, determining the next higher node value with optimal time and space complexity.

We'll cover the following...

Statement

You are given the root node of a binary search tree and a specific node p. Your task is to return the inorder successor of this p node. If there is no inorder successor of the given node, return NULL.

Note: The inorder successor of p is the node with the smallest value greater than p.data in the binary search tree.

Constraints:

  • The tree contains nodes in the range ...
