Q: How to handle huge inputs?

This question evaluates reasoning about scalability, memory constraints, streaming and chunked processing, external-memory algorithms and the trade-offs between time, space, and I/O.

In a coding interview, after you solve a standard algorithmic problem, the interviewer may ask a follow-up such as: "What would you do if the input were extremely large?"

Give a strong, structured answer to this follow-up. Your answer should explain:

what clarifying questions to ask first,
how to reason about whether the data fits in memory,
when it is enough to optimize in-memory space usage,
when streaming or chunked processing is possible,
when external-memory techniques such as disk-based sorting are needed,
and what trade-offs the interviewer is trying to evaluate.

Assume the original problem could be something common like interval scheduling or grouping elements into buckets, but the follow-up is general rather than problem-specific.
