Quick Overview

This question evaluates a candidate's ability to combine tree traversal with coordinate-based grouping and tie-breaking logic. It tests understanding of breadth-first traversal, sorting, and handling nodes that share the same position, commonly used to assess data structure proficiency in coding interviews. It falls under coding and algorithms and requires practical implementation skill rather than purely conceptual knowledge.
