Hello, fishy15
Thanks for the PR

May I know why you want to add these dependencies to the script?
It works without them on my browser

I am using Firefox 109.0 on macOS 13.1. The scripts used to work, but they stopped working maybe a few months ago since it was unable to use the $ and tablesorter variables otherwise. Without those dependencies, I get the following error:

Similarly, if I only include jQuery, then the tablesorter function is not defined. I am not sure why the script is unable to use the libraries on Codeforces itself though.

hmm, I see
I'm using Chrome and Tampermonkey

I would want to apply your change, but another diffrent error occurred when I tried applying it on my local
It sais some function is not found, I think this jquery and tablesorter has overridden the original ones on Codeforces (that's maybe the version is different)

I think Codeforces is still using jquery and related libraries
$ should be able to use
Let me try to find a better solution

Maybe we shouldn't override the libraries on the original site
Otherwise, might want to adjust it to the same version
