Reminder: the contest starts in one hour.
Sad this is going to be the last COCI of the year
Are testers at least 2x times slower than codeforces? It felt like submissions which should easily pass on CF TLEd in COCI evaluator. Or am I estimating my running time incorrectly?
Also, I am not sure if it is done on purpose, but I personally would like to see submissions running time, at least the AC ones.
I think the Evaluator is a bit faster than Codeforces (or approximately the same speed).
The info about running times are unavailable during the contest, but after the contest finishes you can see all the details about all your submissions.
Some hints for (D or B)!?!
And E
