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 and March 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 (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.
TOKI Open Contest January 2018 will be held on Saturday, 27 January 2018, 19.00 — 21.00 Western Indonesian Time (UTC+7). This contest is written by Kwee Lung Sin (Klungs) and Maximilianus Maria Kolbe (Yoshiyuki); also monitored and supervised by Agus Sentosa Hermawan (aguss787), Ammar Fathin Sabili (athin), and Anthony Ng (anthonyhkf).
Several details related to the contest:
The contest will use ACM-ICPC scoring type.
For each division, there will be FOUR (4) problems with various difficulties but the weight for each problem is the same. The contest duration is 2 hours.
The problems are sorted by their expected difficulty from easy to hard. Participants are recommended to read all the problems.
Any non-Accepted submission will get 8 minutes penalty but it will only be counted after the respective problem got Accepted.
The rank will be sorted according to the most number of solves (problems with Accepted verdict). If there are ties, it will be determined by least (sum of solving time + sum of penalties). The rank will be separated for Division 1 and Division 2.
The allowed programming languages are C, C++11, Pascal, Python 3, and Java 8. However, please note that we do not ensure that every language can solve all the problems on the given time limit.
The contest will be held on https://competition.ia-toki.org/contests/253 for division 1 and https://competition.ia-toki.org/contests/254 for division 2. Registration is already opened at the same place. Registering the contest requires a TLX (http://competition.ia-toki.org) account. You may need to register for an account if you don't have one.
