In-Memory SQL Engine
Also known as: In-Memory SQL Engine (Custom)
In-Memory SQL Engine is a simulation problem: follow the process exactly without drifting from the rules. Interviewers love it because it reveals your step-by-step correctness and your edge-case discipline. If you keep the state explicit, you won't get lost halfway through.
