Client-Side API Rate Limiter | Dataford Interview Questions

Implement a client-side rate limiter for API requests. Given a list of request timestamps in non-decreasing order, an integer max_requests, and an integer window_size, return a boolean array where each value indicates whether the corresponding request should be allowed under a sliding-window policy. A request is allowed only if fewer than max_requests requests were allowed in the last window_size seconds, including the current timestamp.

Constraints

1 <= timestamps.length <= 10^5
0 <= timestamps[i] <= 10^9
timestamps is sorted in non-decreasing order
1 <= max_requests <= 10^5
1 <= window_size <= 10^9

Function Signature

def rate_limit_requests(timestamps, max_requests, window_size):
