Question 1
Given a binary tree, how would you find the lowest common ancestor of two nodes if each node also has a parent pointer?
I received an Online Assessment (OA) invitation from Amazon. The assessment consisted of two coding questions of medium to hard difficulty, focusing on data structures, algorithms, and problem-solving skills.
