We are delighted to announce that TOKI Open Contest Special — April Fools is coming again this year! ↵
Moreover, for the first time, we also open this to non-Indonesian coders! :D ↵
↵
**TOKI Open Contest Special — April Fools 2018** consists of "unique" and "oddly satisfying (or annoying?)" problems. ↵
Of course, there is no *division of division*. And oh, every problem is written in English only right now, :)↵
↵
You may see last year's problems of [TOKI Open Contest Special — April Fools 2017](https://training.ia-toki.org/problemsets/86/problems) (only in Indonesian language) or [Codeforces April Fools Contest 2017](http://codeforces.net/contest/784) to grasp the idea of what kind of problems you'll face.↵
