For a data-structure design problem whose behavior is easy to understand but whose implementation is lengthy, describe your step-by-step approach: clarifying operations and constraints, sketching state/transition diagrams, selecting core data structures, reasoning about per-operation time/space complexity, handling boundary cases, and organizing code and tests to minimize bugs.
Quick Answer: This question evaluates a candidate's ability to design and implement complex data structures, testing algorithmic reasoning, time/space complexity analysis, state modeling, and organization of code and tests.
