Problem filtering by tags on ProblemSets on Codeforces.
By ndof, history, 5 years ago, In English

Can I do filtering like tag=dp and tag!=greedy on problem sets.

Actually I do filtering on tag=dp and disables tags view on unsolved problems (to avoid knowing other tags like metrics, tree, maths etc before solving) but it contains greedy problems as well. Thats why wanted to remove greedy from them.

Any trick on this ??

Thanks in advance .. :)

  1. Open two tabs in your browser.

  2. In one of them filter with dp and greedy.

  3. In the other one filter with dp.

  4. Sort both lists with the same order, then solve the problems that appear in the dp list and don't appear in the dp-and-greedy one.

    why do you need two tabs?

      It's because there are so many questions which can be solved by both greedy and DP, That's why they have both the tag's and in general case the greedy solution is obvious and hence seems to us that it's a greedy question instead of DP even though a DP solution too exist.

      To still be able to hide tags for unsolved problems.
