Solution: Inorder Successor in BST
Explore how to find the inorder successor of a given node in a binary search tree by applying depth-first search and BST traversal properties. This lesson guides you through an efficient algorithm that compares node values to locate the smallest value greater than the target node. Understand the traversal steps, decision-making process, and complexity analysis to solve this common tree problem confidently.
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
pis the node with the smallest value greater thanp.datain the binary search tree.
Constraints:
The tree contains nodes in the range
