Sliding window limiter

CodingNetworking & APIsAlgorithms & data structuresMid–Senior~30 min

Implement a sliding-window-log rate limiter. Given a list of integer request timestamps (non-decreasing seconds), a 'limit', and a 'window' size in seconds, a request at time t is allowed if the number of previously-allowed requests with timestamp strictly greater than t-window (i.e. within the last 'window' seconds, half-open) is less than 'limit'; an allowed request is recorded. Rejected requests are not recorded. Return a list of booleans aligned to the input. Empty input returns an empty list.

Implement
sliding_window_log(timestamps: list[int], limit: int, window: int) → list[bool]

in[[1,2,3],2,10]out[true,true,false]
What a strong answer looks like

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
