Algorithm: Topological sort Difficulty: Medium Time: 45 minutes
Return the lexicographically smallest topological ordering of field IDs or null when a cycle exists.
Form Dependency Order is a coding (algo) interview exercise that trains prompt interpretation, explicit assumptions, a concrete response, and a clear explanation of tradeoffs. The catalog marks it as medium difficulty. It focuses on Technical Reasoning, Testing, Validation. The signed-in workspace provides the tools for the round and evaluates the attempt against task-specific criteria. Reference solutions, hidden checks, evaluator instructions, and candidate work remain private.
