TROC announcements are always filled to the brim with emojis as well as very colorful, just like the colors of the writers of this round! Also, as a tester, I can confirm that this TROC has problems. (Who wants to do a problem-less contest?)

    Will there be a contest without problems? The world is already problematic as it is so why bother adding more problems. :(

Problem G is very similar to https://codeforces.com/gym/103102/problem/F, just with one more dimension in dp

wasted 10+ minutes (and 1 penalty submission) because my clarification for problem B asking whether the velocity can still be adjusted at the $$$N$$$-th day was incorrectly answered. I did not notice the correction until I read a Discord message from the committee :'(

I solved problem G right after the upsolving is opened, which is about 3 minutes after the contest ends. If the issue with problem B did not occur, I should have had solved problem G during the contest :'(
