Codeforces Real-time Search Tool

Revision en4, by limabeans, 2020-01-10 09:06:51

Hi all, happy new year!

I recently started developing a new Codeforces Search tool to help search for problems quickly in real-time. This can help for people who want problems for a particular topic (like interval, subarray, permutation, etc).

Right now you can only search by Problem Title, but I intend to add more advanced search functionality (like search by rating, or even search text inside of problems, etc) when I have time.

If interested, please comment below with feature requests and I'll consider adding them -- it'll be more motivating the requested feature can help a lot of people.


Update 1

Thanks everyone who expressed interested via upvoting or commenting with suggestions :)

I have added a couple things:

  • You can click on a column and it will sort that column in ascending/descending order.

  • Search is now global. This means you can search not only by problem name, but also by rating, contest, etc.


html tables are a bit slow to render when they have 5000+ rows of problems, so please be patient when initially sorting and searching. Sorting becomes faster once you've narrowed down the number of rows with a search query. I'm still looking into ways to make the rendering faster.

Also, here are some interesting queries for you to get started:

  • search "Educ" to see all Educational Round problems quickly

  • search "3000" to see all 3000 rated problems

  • search "segment" to see all problems with "segment" in their title

  • search "Div. 2" to see all Div. 2 problems

Let me know if you find any bugs in the comments or if you have any feature suggestions.
