Solution: Find Ancestors of a Given Node in a BST
Explore how to find all ancestors of a node in a binary search tree by implementing both recursive and iterative traversal algorithms in Go. Understand the step-by-step process and analyze time and space complexity to strengthen your problem-solving skills for coding interviews.
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.
