2020 Petrozavodsk Winter Camp, Jagiellonian U Contest

Revision en3, by ko_osaga, 2020-04-22 16:51:46

I uploaded 2020 Petrozavodsk Winter Camp, Jagiellonian U Contest to the CF Gym.

The problemset was used in 2020 Petrozavodsk Winter Camp, and North America Programming Camp 2020. Both ghosts are in scoreboard, so it's a good opportunity to test your skills.

In the version used in PtzCamp and NAPC, problem K had a weak test and the model solution failed in my simple handcrafted tests. I just added that test, and changed the problem limit leniently to allow model solution to pass. I guess this made the problem much easier now.

Thanks to the problemsetters (I don't know who are them). Enjoy!
