Stop writting editorials for MIKE.
By GDCass1ni, history, 9 months ago, In English

I got completely comfused in the editorial of DIV2 E.

let it be number $$$y$$$. Then it is clear that all bits from $$$w$$$ will be included in the answer, then we make a new pair $$$(x'_i, y'_i)$$$ = $$$(x_i - w, y_i - w)$$$

What is $$$w$$$? Where did the $$$w$$$ come from? Are you meaning $$$y$$$ ?

Iterate over bit $$$i$$$ and similarly to the case $$$x = 0$$$ consider the same cases, but for the array $$$y'$$$. Also, take into account that the bit occurs in $$$W$$$.

I think this sentence is written for people who have already known how to solve this problem. It is completely unreadable and meaningless.

Don't write editorials for MIKE. Please, write something understandable.

Please always remember, people who read your editorials do not know how to solve this problem, and not all readers can understand it as easily as tourist.

UPD1: It seems that the writter has modified the editorial and the first issue has been fixed.

Sorry I don't get that your point here, many people who problem set the codeforces rounds are doing it voluntarily; hence, I think you should respect the problem authors/editorial writers more.

Don't be angry about it, instead, you should show the error to the writers under the comments section/private DM to fix it.

I usually find codeforces editorials useful, when I have already solved the problem. Sometimes after reading it I get some insight that I missed, or I see a whole different approach.

But when I am searching for editorial for a problem that I have not solved yet, I usually search through comment section under round announcement.

And if it does not help, sometimes it is useful to find a youtube video of someone high rated, usually their short explanations are easy to understand.

    same with me ,if i have solved the problem the editorial looks quite easy but if i couldn't solve the problem i look for a youtube video rather than looking at the editorial

You know, editorials are always Incomprehensible in codeforces. I usually get a useful one in LUOGU. Although some of them are also bad, I could still find what I need. More is BETTER. Maybe someone is good at creating problems/solving pronlems but not teaching others.

Yeah it seems like the masters/grandmasters who write them assume you are at/near their level. I honestly don't mind the challenge of deciphering an editorial though because I think it helps me really understand the solution, even if it takes a while.

Editorials are mostly useless. They are written for someone who already knows the solution. And if your criticize the editorials/writers you are attacked for not being thankful enough.
