Quick Summary
- Merge pre-sorted event lists from multiple servers into a single chronologically ordered timeline.
- Format each merged event as a string containing timestamp, server ID, action type, and optional target.
- Process multiple sorted inputs efficiently without flattening and sorting all events at once.
What This Tests
- K-way merge algorithm design
- Min-heap and priority queue utilization
- Handling nested map/list data structures
- Optimizing time complexity for sequential data integration
