Pregunta de entrevista de Butterfly Network

The task was to code API endpoints that would "simulate" a CSV—allowing data to be added, retrieved, and manipulated as if interacting with a CSV file. However, the challenge description was vague and lacked sufficient detail, making it difficult to understand the expectations clearly. As a result, I was unable to complete the challenge. That said, the interviewers were very kind and polite throughout the process.
