Interview Questions (1)
Low‑level design of a hash map (test‑driven)
Design a hash map from scratch using a test‑driven approach. Write unit tests that define the expected behavior (e.g., put, get, remove, handling collisions, resizing) before implementing the actual code. Focus on low‑level design decisions such as bucket structure, hashing function, collision resolution strategy, load factor management, and API design.
