Solution: Find Ancestors of a Given Node in a BST
Explore methods to identify all ancestor nodes of a given value in a binary search tree. Learn both recursive and iterative traversal techniques along with understanding their efficiency and space requirements in different BST scenarios.
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.
