Solution: Logger Rate Limiter

Explore how to implement a logger rate limiter system that prevents repeated messages within a set time frame. Learn to use hash maps to track message timestamps, optimize decision-making in constant time, and reduce duplicate logs effectively.

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 $S$ 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:

$1 \leq$ request.length $\leq 10^{2}$
