OMG a TROC!!! JvThunder can you see this???
Wait what? Another TROC? OMGGGG!!!
IT'S DONE ALREADY ?????? WHAT ???
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?)
Waiting for a problem-less TROC...
I suggest we create a bugaboo-filled, problem-less TROC!
in TROC #26? :o
Will there be a contest without problems? The world is already problematic as it is so why bother adding more problems. :(
As a problemsetter, I can ensure you that
.
As a tester, I can also confirm that this TROC has problems
UWOOOOOOGGGGGHHHHHH!!!!!! TROC!!!!!!!
Imagine a TROC announcement without shitposts
That's like imagining joshjms having a girlfriend
Please note that this contest is at the same time as Codechef Snackdown (and corresponding parallel contest)
Yeah, another TROC round :)
Friendly bump! The contest will start in less than 4 hours, good luck and have fun! :D
Another friendly bump! 30 minutes before the contest starts. Good luck :D
Problem G is very similar to https://mirror.codeforces.com/gym/103102/problem/F, just with one more dimension in dp
among us in real life
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 :'(
