Find the maximum depth of a binary tree.
AI-Expanded — inferred from the question title, not from the original candidate report
Given the root of a binary tree, write a function to determine its maximum depth, defined as the number of nodes along the longest path from the root node down to the farthest leaf node. Your solution should return an integer representing this depth, where an empty tree has a depth of zero.
Context & Summary
Second round began with an introduction followed by questions on projects. The interviewer revisited 3 questions from the first round, focusing on pointers, signed and unsigned integers, and probability. Additional questions were asked on anagram checking, maximum depth of a binary tree, pass-by-value vs. pass-by-reference, stack overflow, stack usage, recursion, cache performance in loops, and multithreading with semaphores.
