Collapse request status log
Your task
A mobile client retries flaky uploads, so the ingestion log can contain several lines for the same request id, each of the form "<request_id> <status>". Later lines for an id supersede earlier ones. Collapse the log so each request id appears exactly once, formatted as "<request_id> <status>" with its most recent status, but keep the ids in the order in which they FIRST appeared. Return the collapsed lines.
Examples
dedupe_retries(lines: list[str]) -> list[str]Example 1
Input
dedupe_retries(["r1 pending", "r2 pending", "r1 failed", "r1 succeeded"])Output
["r1 succeeded", "r2 pending"]
