Last year at GoodBye2023 there were also some mistakes by the authors, which seemed to me to be much larger. So I hope that this next year will be better than the previous one)
I also wonder if anyone was able to come up with the right solution for I2 or is it impossible?
P.S. Also here is my experience of solving this problem: looked closely at the code for I1 -> hmm this should be improved to I2 by simply adding a few structures -> started writing the code -> after 5 minutes realized that some arrays are taken into account several times -> stop writing -> think -> go to problem H.
