Good Luck to everyone.

let's go!

good luck to everyone giving it

Orz

On the last conteset, I only have 300 scores. I'm very mad.

Thanks to Atcoder that it is SOOO consistent, in contrast to codeforces unfortunatly... :(

Good luck to everyone!

Good luck guys

Hope AC E vOvOv

yay i hope i do atleast 2 questions today :) goodluck

Hope everyone can get good score

Good Luck!

Hope to AK!

qpzc

oh, I can't access atcoder.(sad I got only 300points qwq.

SUPER RUBBISH ROUND.

why is it so hard???

i got 1575 last round and 300 this round...

DOWNVOTE!SUPER RUBBISH ROUND.(

Worst ABC I have seen.

Sorry, but D was one of the most annoying, tedious case work problem I've ever encountered on AtCoder. I genuinely hated this round.

Anybody else use PBDS to solve C ?

very bad round

this was the first time i ever gave a contest, i could only do A and B, that is all, I got fileted by question C, Its over, life is not worth living

how to solve C

Is there any optimal approach other than LinkedList for question F.Erase between X and Y

why is f easier than d and e

great round

problems were a mess—either too boring or way too complicated. The difficulty doesn’t make sense, and some problems seem designed just to waste time

F<<<<<D

upd: i can somehow understand that D is much easier than E in thinking of their solutions, but how the hell is a linkedlist F? in terms of thinking F≈D and in terms of coding F<<<<<<<<<D

RUBBISH ROUND. 300 ppl E 600 ppl F 130 ppl G

Wasted so much time on E(still don't know how to solve it) makes me have no time to solve G.

trash D, G is great.

我过了ABCDEF,G来不及看

Worst ABC.

For question D i tried to do some simulation like this can someone tell me why it wont work , i tried merging line with like similar direction updates to make a straight line and check their intersections

  while (!dq.empty() && !dq1.empty())
        {
            ll copies = 0, copies1 = 0;
            auto curr = dq.front(), curr1 = dq1.front();

            while (curr.s == dq.front().s)
            {
                copies += dq.front().a;
                dq.pop_front();
            }
            while (curr1.s == dq1.front().s)
            {
                copies1 += dq1.front().a;
                dq1.pop_front();
            }

            line end, end1;

            apply(end, curr.s, start, copies);
            apply(end1, curr1.s, start1, copies1);
            line res;
            res.x = LONG_LONG_MIN;
            if (doIntersect(start, end, start1, end1, res))
            {
                // overlapping ho rhi bahut bhayankar
                if (res.x == LLONG_MIN)
                {
                    if (start.x == start1.x && start.y == start1.y && prev1 == prev2)
                    {
                        ll len1 = manhattan(start, end);
                        ll len2 = manhattan(start1, end1);
                        ans += min(len1, len2);
                    }
                }
                else
                {
                    ll dist1 = manhattan(start, res);
                    ll dist2 = manhattan(start1, res);
                    if (prev1 + dist1 == dist2 + prev2)
                        ans++;
                }
                start = end;
                start1 = end;
                prev1 += copies;
                prev2 += copies1;
            }

rubbish round

D is sh*t!

very bad round,downvote!!!

The worst one I have ever seen.Why are you guys always giving out stupid problems to us?

A shit contest.

hp

F is a lot easier than D and E. D was too impl heavy + boring and hence had no motivation to solve it. Really feeling the quantity over quality...

For F, an offline way to check if X comes before Y: Create the digraph (type 1 x->i) and check toposort order.

D is a bit boring with heavy implementation. I have no motivation to solve the problems :(

D是什么东西 D is 【"Harmonious" words】

The worst ABC I have participated! Downvote it! Make it be the end of CodeForces!

F is much easier than E and D. Swapping E and F makes a lot of sense.

swap(D, F) plz... D is tooooooooo boring.

what a super rubbish round.

awful contest.

Hope can replace D with F.

I am so mad when I have WA*10 in D everytime.

Shit Contest

Atcoder Implementation Contest

Fuck D

史

this contest is meaningless at all

Oh, this contest is the WORST one I've taken part in.

Why is the next ABC on Sunday at 12:10 (Beijing time)

SUPER RUBBISH ROUND

i got 2575 last round and 600 this round...

Bullshit contest.

I am new to AtCoder, how much time does it take tentatively for the ratings to update?

No comment. Plz downvote this ??? contest.

Although I got a good result, I still have to say that this contest was really bad, especially the D problem.

The person who created the question will be criticized as Fwb

It's hard to believe that scores of 650 and 2025 came from the same contestant. I think it was a bad round.

atcoder 正在蒸蒸日上

downvote to this problem. this contest is the same rubbish as abc387
