This was my first ARC. I only solved one problem after a long time, are all ARC this hard?
I hate permutations.
The word "permutation" appears in the statement of every problem.
good picture. can i share it?

Can't say PermutationForces since it's atcoder
damn A is toooooooo hard
fr
what was that !!!
B<<<<<<A
Although problem A shouldn't be at A, it's an excellent problem!
The contest is not competing about who's better at CP, but about who can solve B faster. The one ranked 77 who solved only B gets 2592 perf. The one ranked 506 who also solved only B, gets only 1623 perf.
Please consider making ARC (or at least ARC++) rated for everybody with rating [1600, INF). The problems are clearly challenging enough.
Since AGC is so rare,it is a correct choice to adjust the rating range of ARC++ to [1600,INF)
How about making them rated for 429 to INF since I'm 429 rating?
A is very challenging. I was stuck on the case that "P(i)=Q(i)" and didn't realize that we can tag the numbers 0/1 and for all of the tags do the count. Nice problem!
It was too difficult for me to FINISH A
My AT rating is less than 500
