Stream Log Deduplication Window

Problem

Given a list of log entries logs representing a continuous stream and an integer window_size, write a function that returns the log entries after removing duplicates seen within the most recent window_size accepted entries. Preserve the original order of kept logs. A log is considered duplicate if its exact string value already exists in the current deduplication window.

Constraints

• 1 <= len(logs) <= 10^5
• 0 <= len(logs[i]) <= 200
• 0 <= window_size <= 10^5
• Log comparison is exact and case-sensitive
