Design a Read/Write-Optimized Data Structure (General Coding, Non-ML)

75-min Coding Interview: Design a Data Structure Optimized for Reads and Writes Implement a custom data structure in a language of your choice that is optimized for both reads and writes. The prompt emphasizes: Not related to AI/ML No complex algorithms (more about engineering design & clean code) You may Google standard library usage Evaluation focuses on problem solving and clean, well-designed code What you are expected to do (recoverable from the post) Define a reasonable API (e.g., read/write/update operations). Explain trade-offs for read vs. write performance. Produce runnable code and walk through examples. Tests & constraints The post does not specify the exact API, I/O, performance targets, read/write ratio, capacity limits, or concurrency requirements, so it cannot be reconstructed into a fully specified coding problem.
