Hello!↵

Indonesia will hold 2017 National Olympiad in Informatics next week (July 3rd — July 5th 2017) in Pekanbaru, Indonesia. It is a competition for Indonesian high school students as one of the preliminary round of Indonesian IOI selection. ↵
↵
And this is the third year for Indonesia ([2016](http://codeforces.net/blog/entry/44892), [2015](http://codeforces.net/blog/entry/17924)) to invite everyone around the world to try solving the problems by participating the Open Contest! The contest will be conducted on [TLX Online Judge](https://competition.ia-toki.org/contests). You may need to register for a TLX account if you do not have one. If you have a TLX account, you can login and go to the contest link to register for the contest.↵

There will be three different contests, one for each day. You may participate them separately (e.g. only participate in Day 1 and Day 2, but not in Day 0), but we expect you to join them all.
