About Algorithm Notes

Algorithm Notes is an independent educational reference rebuilt from verified historical archive evidence. It turns recoverable interview-problem topics into newly written explanations rather than copying archived pages.

Editorial approach

Each article identifies its evidence tier, historical source path, and Wayback snapshot. The archive proves that a topic existed; the published explanation, examples, and structure are independently rewritten and manually reviewed.

Independent status

This site does not claim ownership of the historical domain or affiliation with the companies, interview platforms, or archives mentioned in source notes.
