Solution: Logger Rate Limiter
Explore how to implement a logger rate limiter system that prevents repeated messages within a specific time frame by using hash maps. Understand both naive and optimized approaches, focusing on managing message timestamps and ensuring efficient message filtering with constant-time lookups.
We'll cover the following...
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 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:
-
request.length
