I was training in the gym. When I tried to solve the problem H in ECPC 2013(gym number 100283), I've got Denial of judgement verdict. See 6939694.
I suspect that the special judge for the problem crashes. I have little clue how to fix the crashes. Could anyone give me an advice? I'd love to do some work if necessary.
It was not because of broken checker but because of main solution. It was too slow to fit in TL, I replaced it with vepifanov's solution.
Thank you for taking the time to look at this.
