Solution: Find Ancestors of a Given Node in a BST
Explore how to identify all ancestor nodes of a specific value in a binary search tree. This lesson covers both recursive and iterative solutions in Java, explains their implementation steps, and discusses time and space complexity for effective coding and interview preparation.
Statement
Given the root node of a binary search tree (BST) and an integer value k, find all the ancestors of the node whose value is k.
An ancestor of a node in a tree is any node on the path from the root to that node.
Constraints:
Let n be the number of nodes in a binary search tree.
