Interview Prompt
A monitoring service records maintenance windows as `[start, end]` minute offsets in `windows`, arriving in no particular order and often overlapping or fully containing one another. Collapse them into the fewest non-overlapping windows that cover the same time.
Summary
Overlapping outages hide how much time is really dark. Collapse them into the truth.
