In problem [INMAT][1], I get this type of verdict of WA (-1.000000) and WA (0.000000) !! What does WA (-1.000000) mean ?

Maybe it means that you’re using more operations(K) than allowed.

@mgch, I am getting this type of verdict (refer link)!!

A verdict of -1 time tells that the something which you did made interactor violate one of the assertions throwing a RE error. It means you are not adhereing to the constraints (eg- at most K queries).

That is either because your output buffer is not clear or because you are making more operations(k) than allowed.

the cordinate compression qs is quite unclear. what does it mean by the subsequence amax(1,i-k)…amin(N,i+k)

I have a doubt in problem INTERACTIVE MATRIX problem statement. Can I ask it here? I asked it in comments sections 3 days ago but no one replied yet :frowning:

@admin @mgch please someone reply :frowning:

The problem statements are very much clear. I didn’t had any doubt while reading. May be you just need to read the problem more carefully!

@jagreetdg As, far as I know, you are not allowed to answer any query related to the problem statement, even if it’s a clarification of problem statement. Otherwise I could have replied to it the day it was asked.
someone please correct me if I am wrong(I don’t know rules properly)…

@pshishod2645 - Yes, you’re right. I deleted that comment now. @all please note that, posting your clarification requests is here primarily for contest admin @mgch to see in case the setter is not looking (so @mgch can contact the setter and get things right.) Other things may include addressing any serious complaints you got against anything during contests &etc. (You might be asked to discuss it elaborately over a private channel depending on if its fair to make it public).

As the setter, I would also like to clarify that I intentionally publish all comments so that others are aware of what doubts are being asked and expect them to atleast see the comments before asking their doubts as it is very annoying to write the same reply everytime and if I try to not reply, people rant everywhere that there doubt was not clear. So, I expect people here to also understand that they should also keep on looking at comments if something is not clear and ask a question which has not been asked before, I would be happy to clarify your doubts.

Also, please don’t hints regarding solution or more test cases.

I liked all these problems, and they’re all easy to understand, even MYST is clear when carefully read. Don’t know why so much question in coordinate compression. But I have problem with that idiot prince. 4 days ago I thought I found the solution and got 10 points with quick coding, and good partially correct answers. Improved it a lot with hundreds of custom tests, fixed little bugs since then but after 4 days later I’m still getting the exactly same result. Now I’m stuck and don’t wanna touch to any other problem… I’m gonna kill that prince myself… or let me try to put a big sign saying “Sorry prince but our princess is on another land” :stuck_out_tongue:
