Hi everyone,
I have a question about searching problems in the Problemset.
Sometimes I want to practice problems while avoiding certain topics/tags. For example, I may want to solve problems of a particular difficulty range but exclude some tags that I'm not interested in practicing at the moment.
I know that Codeforces allows filtering by tags, but is there a way to search for problems while excluding specific tags?
If not, how do you usually find problems that avoid certain topics? Do you use any built-in filters, mashups, or external tools?
Any suggestions would be appreciated. Thanks!
Hi Double2D, Thanks for asking this! Codeforces natively only lets you include tags, but your post actually gave me an incredible idea.
I recently built an open-source extension called CF Monolith to create a cleaner, unified workspace for Codeforces. Because of your post, I'm working on adding a "Tag Excluder/Filter" feature into the next update so users can easily hide specific topics (like DP, math, etc.) while practicing.
If you want to check it out or track the upcoming feature, you can find it on the Chrome Web Store as CF Monolith. Thanks again for the great suggestion! Google web store:(https://chromewebstore.google.com/detail/codeforces-monolith-cf-mo/alailmojcgnjfgclagniegeeaeecndni)
