lol, didn't u participate in previous 3-4 contests ?

Can you tell the logic of c

Since time immemorial, outstanding individuals have emerged from the oceans of mediocrity that make up the vast majority of humanity. Great thinkers destined to change their respective eras, launching the world into a new epoch. Mike4235 is the undeniable peak of what an outstanding individual is — he is the peak of what humanity can ever possibly achieve, the apex of human evolution and society.

If enlightenment is theoretically achievable, then Mike4235 is the sole example of enlightenment. There has never been a greater mind in the millennia of human civilization — from the great minds of Socrates, Confucius, Hegel — Mike4235 remains to be the apex of human development. It is the duty of every man and woman to dedicate their lives to the pursuit of what Mike4235 stands for — the progression of humanity into a greater version of ourselves.

Mike4235 is utter perfection in every sense of the word — even beyond. Human language cannot even begin to describe the earth-shattering qualities that he possesses. A fashion sense that makes ordinary humans appear as nothing more than bland specks of dirt. Intelligence that renders the complex processes behind a super-computer to resemble nothing more than a mere abacus. Humility that makes the martyrs of history seem like naive children.

Compared to Mike4235, we are all but measly insects that exist to eat the feces of superior beings, naive and ignorant creatures that wander the Earth without a sense of understanding of the grandiose knowledge that the universe offers.

Mike4235 is the peak of human evolution, and we can only prostrate ourselves to his superiority. He will not be merciful on our souls, and we must only accept his divine judgement.

If he commands us to lick his boots, we shall slurp every particle of filth and bacteria that dares to contaminate the paragon of humanity’s shoes. It shall be so pristine, that it will reflect the face of inferiority.

If he commands us to donate money, then we shall empty our coffers for him. By his impulse and will, we shall learn what true humility is.

Those who refuse the ever-existent superiority of Mike4235 will only be dooming themselves to a life of trifle purpose. Mike4235 is not a god — he is beyond what ordinary humans can even conceptualize as a deity.

Repent now, and see Mike4235 as the true exemplar of the sublime, lest you fade into the trenches of human society, destined to be forgotten.

Most importantly, pretests = tests

And C is probably the easiest C. :(

Got it, thanks!

It will be a good idea to assign points to a problem based on the number of correct submissions after the contest?

1 & 2 = 0 so Div. (1 & 2) = Div. 0

still an expert i see, luck was on your side haha :D

Yes Website Down is Really Sucks !

Would be better if they ignore mirror website's submission if the solution is submitted already on main website.

there are multiple solutions...It appears they haven't implemented any. although they do have a mechanism of filtering out same submissions if you make one after the other, but this probably happened because the 1st solution was maybe queued when the 2nd also got queued through a mirror website. but definitely some mechanism needs to be in place to avoid such things as codeforces being down hasn't been a rare event recently.

All solutions mentioned here are actually different (probably equivalent but the files are not equal). For submissions of i_pranavmehta other compilers were used. I don't think Codeforces should handle cases like this.

I'll improve protection against submitting exactly the same code, but discussed cases are not about it.

Fix the starting point of subarray at i, then iterate on its end j. Let's say you can efficiently find a[j]'s correct position in the sorted subarray of a[i...j], say k. Then you need to sort between [k...j]. You already know previous segments which you need to sort in a[i...j-1], then try to see how will the answer change

For me even D2D1 was a little too hard

I did consider that and I couldn't solve it :/

I had this idea during the round but couldn’t figure out how to calculate that number in O(1). Could u please explain how to use monotonic stack for that?

oh my god fast io fixed it im gonna go kms now

From what I remember, prev(set.upper_bound(...)) can work in higher time than log(n).

ok tbf, test 8 is the last pretest, so it's likely that many solutions actually managed to pass pretests with $$$n^2logn$$$. Unfortunate :(

my one passed in 500ms

Yeah, this is the only submission which hasn't been judged yet

Congrats on solving B in contest, oh wait you got neither B1 nor B2 in contest.

(My point isnt to belittle you, rather things look much easier in retrospect than in actual contest, one should be mindful of that)

My Go solution passed in 500ms, i was a bit scared
