Question
A health checker appends one line per probe: "<timestamp> <service> <status>", where status is "ok" or "fail". An incident page should fire when any single service fails n times in a row — counting only that service's own probes, in log order; probes of other services in between do not reset the streak. Given the log lines and n (n >= 1), return true if some service reaches n consecutive "fail" probes, and false otherwise.
has_consecutive_failures(lines: list[str], n: int) → bool[["t1 db fail","t2 db fail","t3 api ok","t4 db fail"],3]outtrueState your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.
