Answer: No

## Analysis of the Hopping Window Solution ### Goal Requirements: - Count tweets in **each 10-second window** - Ensure **each tweet is counted only once** ### Hopping Window Behavior: A hopping window with **5-second hop size** and **10-second window size** creates **overlapping windows** that advance every 5 seconds. This means: - Window 1: 0-10 seconds - Window 2: 5-15 seconds - Window 3: 10-20 seconds - And so on... ### Problem with Overlapping Windows: - **Tweets occurring between 5-10 seconds** would be counted in **both Window 1 and Window 2** - **Tweets occurring between 10-15 seconds** would be counted in **both Window 2 and Window 3** - This violates the requirement that **each tweet must be counted only once** ### Correct Window Type for This Scenario: A **tumbling window** with 10-second intervals would be the appropriate choice because: - Tumbling windows are **non-overlapping** - Each tweet falls into exactly one 10-second window - No duplication of tweet counts occurs - Meets both requirements: counting in each 10-second window AND ensuring each tweet is counted once ### Why This Solution Fails: The hopping window with 5-second hop creates 50% overlap between consecutive windows, causing tweets in the overlapping regions to be counted multiple times. This fundamentally contradicts the "counted only once" requirement. **Conclusion:** The solution does NOT meet the goal because the overlapping nature of the hopping window causes tweet duplication.
