Interview Prompt
The content team is pruning dead pages, where each page_url is already stored in its final canonical form and should be treated exactly as recorded. Find the content with the fewest unique viewers, counting a visitor who returns to the same page many times only once. If several pages share that lowest viewer count, include all of them.
Summary
Nobody is watching. Should it still exist?
