Solution: Logger Rate Limiter

Explore how to build a logger rate limiter that determines if messages should be displayed based on timestamps using hash maps. Understand time and space complexity trade-offs, compare naive and optimized approaches, and implement an efficient solution that rejects duplicates within a time window.

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}
