About Codeforces Notes

Codeforces Notes allows you to take notes on the problem page. You can take notes while solving the problem, or after you’ve solved it. Simple, but powerful! - The idea: Writing “what you learned” once you’ve solved a problem helps you retain the learnings for a long time. This method of practice is used by countless competitive programmers. - Notes are safe: The notes are attached to your email address, this allows them to be retained across machines and codeforces accounts. Future updates: - “Export to CSV” will be added ASAP. - “All notes” option on your codeforces profile page
