Algorithm questions primarily from linked lists, graphs, stacks, and queues
AI-Expanded — inferred from the question title, not from the original candidate report
Given a directed graph represented as an adjacency list, implement a function that uses a queue to perform a topological sort of the nodes. If the graph contains a cycle, the function should return an empty list; otherwise, it should return a valid linear ordering of the vertices such that for every directed edge from node A to node B, A appears before B in the sequence.
