Solution: Find Ancestors of a Given Node in a BST
Explore how to find all ancestor nodes of a given value in a binary search tree using both recursive and iterative techniques. Understand the step-by-step process to traverse the tree efficiently and analyze the time and space complexities involved. This lesson helps you apply tree traversal concepts to solve typical coding interview problems in JavaScript.
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.
