Solution: Logger Rate Limiter

Explore the implementation of a logger rate limiter that filters out repeated messages within a given time window. Learn how to optimize this solution using hash maps to achieve constant-time message checks and efficiently handle incoming message streams based on timestamps.

Statement

For the given stream of message requests and their timestamps as input, you must implement a logger rate limiter system that decides whether the current message request is displayed. The decision depends on whether the same message has already been displayed in the last SS seconds. If yes, then the decision is FALSE, as this message is considered a duplicate. Otherwise, the decision is TRUE.

Note: Several message requests, though received at different timestamps, may carry identical messages.

Constraint:

  • 11 \leq request.length 102\leq 10^{2}
