Hello Codeforces,↵
↵
It has been a long while, but in [this project](https://github.com/fjzzq2002/is-my-problem-new) we close the long-standing open problem proposed by [Umnik 2021](https://mirror.codeforces.com/blog/entry/95956). You can try it[here](http://45.63.4.94:1234/) (deployed on my tiny server, be nice!) _(discontinued, see the new link below)_ while supplies last. Currently I only imported problems from Codeforces & BZOJ (the dead Chinese OJ) but adding other OJs should be easy as long as we have the statements crawled (PRs?).↵

Cheers! Cheers!↵

**Update (8 months later):** We finally got an update! In the new version I collected and uploaded most of vjudge (which means 160k problems!). It also got a shiny new domain [http://yuantiji.ac](http://yuantiji.ac). Enjoy! :D
