Codeforces Ladders A2OJ web app to see your progress.
By Isanchez_Aguilar, history, 5 years ago, In English

Currently I developed a web app using the codeforces API. Due to current situation of a2oj.com https://mirror.codeforces.com/blog/entry/71249, for most people that known the list of problems ladders from Codeforces and still solving this problems is a little difficult to see your progress due that only exist the static version of ladders but with this proposal I hope be helpful and you enjoy it. This is the first version, It is simple but with main functions to see the progress in solving ladders problems of any user of codeforces, If you found some bugs or have any opinion about new features please tell me as you know this is first version and I will work for better version.

Notes:

  1. You can see the list of problem without introduce your user handle.
  2. If you want to see your progress just introduce your user handle.
  3. If you submit any problem this web app is making request to codeforces API that means that your progress must update and reflected in table and user information without refresh the web page.

Why split problems in groups of 10? I think making all 100 problems from a ladder appear on the same page would make it more identical to the a2oj ladders. BTW, nice work.

    YES! I think it's a good idea to put more problems per page. Thank you!

How a level is assigned to a problem ?

1800-1899 ladder means 1900 difficulty problem in codeforces ?

One more Problem which will be helpful if corrected!! Some problems are common in Div 1 and Div 2 rounds I have submitted my code on problem 373C(Div-2) but not on 372A(Div-1)

and your webapp shows me that I have not solved 372A (Ladder 1400-1499) It would be beneficial if corrected Thanks and regards

Thank you!!! and it would be nice if it had a side menu instead of the tab bar (makes it simple to navigate).
