It's a bowing down sign

orz

ahsoltan can you please add the implementations

can you explain for the 2D thing the editorial says to match Xl∩Yl with a point in Xr∩Yr but how to implement this idea and also which point to choose from both the sets.

Yes

countful thanks!! xD

I'd like to see the proof of D2C I'm sure most of the people guessed it

I knew it so didnt give it :)

Can you explain your solution? I did not understand it. Edit : I understood it from another comment. Thanks for the new idea.

Thanks

Let's go I might become expert today then love you <3. Also loved the problems c and d especially

Sometimes I myself come up with a solution that I can proove why it works but I don't know how did the solution come to me and I would try to back track my my chain of thoughts, sometimes I fail to backtrack simply because the solution randomly appeared to me and that feels unsatisfying and I remain irritated with that.

Call me too, despite having so many authors and testers this is pathetic

So true, F was so baddddddddd. I dont know what were the authors high on while keeping F at F

wdym you really think F was worth F?

As a specialist I have never read E in div2 contest within contest

Codeforces : 1577 , Lichess : 1655

When will the editorials be released? Also I wanted to add that the problems were good but please make the testers proof read the final problem statements, c had so many issues, b was unclear, a didnt mention if it was a decimal symbol or multiplication symbol. I hope youll fix these issues next time. Also i wanted see proof of correctness of problem D. [I am talking about the Div2]

very true c had so many issues

Can someone please tell why does this get tle how do i optimise this solution

Pray to god

Worst E ever. I appreciate that the author thought of such a creative idea but still Im not conviced this was a good E

fr

was E just a luck checking task or there is some formal proof ?

Mee tooo (I'll try to ak it)

nice one !!!!!

I did proove for B, rest of it i just guessed too, i dont know if it just me , but it feels annoying to give 2.5hrs and get nothing of it and also its so unsatisfying to guess and pass

Couldn't solve this (Gave brute force)

F was smart

Or he is so smart that he is trolling codeforces and you guys, to escape WA penalty this is a clever way

I agree

lmao this is barely 1000 rated greedy problem

Yeah higher the jump in between the problems higher is the difficulty change

sadly, i agree to that and have seen my college mates getting penalised often
