Compare common data structures and uses evaluates algorithm design, data structures, correctness, complexity, edge cases, and implementation details in a realistic interview setting. A strong answer states assumptions, handles edge cases, explains trade-offs, and shows how to validate the result clearly.

Compare common data structures and select appropriate ones for specific tasks. For arrays, linked lists, stacks, queues, hash tables, binary search trees (balanced and unbalanced), heaps, and graphs, state average and worst-case time/space complexities for search, insert, delete, and iteration; list key invariants; and provide one example where each excels and one where it performs poorly.
