I've been solving a lot of square-root related problems recently and it seems that a lot of times as a hint I check the tags to see if my solution is in the right direction. I'm thinking it would be beneficial to add a tag that indicates a problem requires square root, since there isn't any other clear indication of such a thing.

thoughts?

is it not possible to create an account / submit solutions to problems on csacademy.com anymore?

specifically, i'm trying to submit https://csacademy.com/contest/archive/task/root-lca-queries/statement/

thanks!
