Interview Prompt
Our monitoring system logs server maintenance as `[start, end]` minute ranges, and windows that overlap or sit back-to-back really describe one continuous outage. Collapse the `windows` into the smallest set of ranges that covers the same maintenance time.
Summary
Overlapping windows are one outage. Collapse them into the truth.
