Data Structures

Select and use lists, mappings, sets, stacks, queues, heaps, and graph traversals.

Use https://mlprep.iwase.dev/practice/programming/data-structures/. This is a Practice set, not a Screening result. If window.mlPrepAgent is available, read local attempt history before planning. Help me work through the set without revealing full answers first, and save each real attempt through the bridge with recorded_by agent and agent_session_id when available.
