Hello Codeforces Community, TOKI Open Contest is back again! :D↵
↵
We would like to invite you to participate in this TOKI Open Contest January 2018. TOKI Open Contest is Indonesian monthly online programming contest. It's been a long hiatus since we decided to make this contest international: on [February](http://mirror.codeforces.com/blog/entry/50318) and [March](http://mirror.codeforces.com/blog/entry/51134) 2017! :')↵
↵
Every problem is written in both Bahasa Indonesia and English. The contest will be divided into **two divisions**: Division 1 and Division 2. It is pretty similar to the divisions in [Atcoder](http://atcoder.jp/) (Beginner and Regular). You are free to register in any division (it's extremely OK if you are a Div2 Codeforces user and register to our Division 1 contest)! The expected difficulties of the problems are much the same with Atcoder's contest problems.↵
