Max Latency per Timestamp | Dataford Interview Questions

Given a log file with columns timestamp and latency (unsorted, repeated timestamps), print for each timestamp the maximum latency, sorted by timestamp.

Asked in the onsite stage. Practical SRE-style log parsing task.

Implement max_latency_by_timestamp(records), where records is a list of [timestamp, latency] pairs. Return a list of [timestamp, maximum_latency] pairs ordered by ascending timestamp. Return an empty list when the log has no records.

Constraints

0 <= len(records) <= 5000
Each record contains exactly two integers: [timestamp, latency]
Timestamps are integers
Latencies are non-negative integers

Function Signature

def max_latency_by_timestamp(records):
