Solution: Logger Rate Limiter
Explore how to design a logger rate limiter system that controls message display based on recent duplicates. Understand naive and optimized hash map approaches to implement constant-time checks for repeated requests within a time window, improving efficiency in message handling.
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
