Dear all,

You may have used https://kenkoooo.com/atcoder#/table/ to check for Atcoder Problems and their difficulties. I like this tool so much that I decided to write a CF version of it (I have got permission from the author to copy the exact same style of his website).

It has been posted on my blog https://tom0727.github.io/cf-problems/.

Here is a preview of it:

If you encounter any problems using this tool, or you have a bad experience using it on phone, please inform me, thanks!

• This list is updated automatically every day.

Update1: It is a good idea to add Login function and track AC status of the problems. I will work on this feature recently. For other features, since this page is written in pure html/css/js, it might be costly to add new complicated features. Therefore I plan to refactor this project next year if there are many people using it.

Update2: Added Login Feature! You only need to input the handle, password is not needed! Also when you mouseover a contest name, the whole name can be shown. Enjoy!

Update3: The contest names are shorter now, the rendering logic has been changed to make the page faster.

Update4: Fixed a bug where some new contest problems have rating "undefined". Now the list will not contain any problem that does not have a rating.

Update5: The tool is now updating automatically everyday.

    Thank you for your reply! I currently do not plan to add the feature of tracking AC status, mainly because of my limited frontend knowledge and time. I may consider adding new features next year (that is when I have finished my application of graduate schools).

Thanks for this wonderful tool. But can you tell me how to find an educational round in that? Sorry if I'm not able to find that?

Just getting handle name and updating the table with AC status might be a quick solution while you are implementing full login features.

Thank you! It is really cool.
One request, Can you remove "Codeforces Round", "Educational Round" etc prefixes from Contest name column so that one can see Contest number only in the column itself, and don't have to hover over the contest name to see contest number in tooltip. For example, #644 (Div.3) in Div 3 list. It will be much better experience that way.

    It is updating! I just removed the gitee link, originally it is for serving Mainland China users, but because of regulations gitee is not available now.

    You can still get everything from my github blog!

Do you have to update it manually each time there is a new contest? I am wondering why the most recent CF rounds (745, 746) are not visible here.

    The update is automatic. It is done every 3 days. And for a contest if the problem ratings are not yet released, then the list will not include this contest. So please do wait for a few days, it should be appearing soon!
