Contest day 2: https://dmoj.ca/contest/cco20d2

Hi CodeForces,

DMOJ will host a mirror of the 2020 Canadian Computing Olympiad this Wednesday and Friday 3:00PM ET.

The start time will be approximately 2 hours after the end of the official competition. Timeanddate links can be found within the links above. It will be a 3-problem, 4 hour contest, similar to IOI-style.

If the mirror time doesn't work for you, the problems will still be available for solving afterwards on the main judge. Good luck and have fun!

Are editorials published anywhere for CCO problems?

    Did you find Editorials? Or can you please share your ideas/strategy for the problem a game with grundy . Only thing i could think of other than using a prefix sum for the first subtask is to use a segment tree. But it got RTE. (i was kinda expecting that).

    thank you.
