Hot on the heels of Finland's contest, the Swedish olympiad finals also took place this weekend, and for those who want to try out the problems, we have put up a site where you can participate during any 5 hour period during this week: https://pofinal19-open.kattis.com/.

If you don't have 5 hours to spare you can also look at the problems directly at https://pofinal19.kattis.com/. The last problem is IMO quite neat.
