Most Frequent Event from Timestamps | Dataford Interview Questions

Given a list of events, each with a message and a timestamp, extract the most frequent event and return its timestamps for further analysis.

Asked in the coding round 1 stage. Example: [{"message": "error_1", "timestamp": 123}, {"message": "error_1", "timestamp": 234}, {"message": "error_2", "timestamp": 456}] returns {"message": "error_1", "timestamps": [123, 234]}.

Implement most_frequent_event(events). Each event is a dictionary with string message and integer timestamp. Return the timestamps in input order. If multiple messages tie, return the one appearing first. The input is non-empty.

Constraints

1 <= len(events) <= 1000
Each event contains a non-empty string message and an integer timestamp
Return timestamps in their original input order
If frequencies tie, choose the message appearing first

Function Signature
