Solution: Logger Rate Limiter
Explore how to build a logger rate limiter that filters duplicate messages within a specified time interval. Learn to apply hash maps to track message timestamps efficiently, ensuring constant time checks and updates. Understand the balance between naive and optimized solutions and their time-space complexities.
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
