Hi Codeforces Community,

I would like to invite you to participate in TOKI Open Contest. TOKI Open Contest is our (Indonesian's) monthly/bi-monthly online contest. Starting this month, we have decided to make this contest international :) Every problem is written in both Bahasa Indonesia and English.

TOKI Open Contest February 2017 will be held on Saturday, 18 February 2017, 19.00 — 21.00 Western Indonesian Time (UTC+7). This contest is written by athin, anthonyhkf, aguss787, and I.

Several details related to the contest:

1. The contest will use ACM-ICPC scoring type.

2. There will be FIVE problems with various difficulties but the weight for each problem is the same. The contest time is 2 hours.

3. Any non-Accepted submission will get 8 minutes penalty (but the penalty will only be counted after the respective problem got Accepted)
