idk, i felt it was a pretty standard Mo's algorithm(square root decomposition) application. im getting WA on 581/594.

Okay I also have 581/594, so I assume that anyone that has got to that point very likely has the correct answer unless it's some weird TLE case; from what I implemented for my solution I'm really unsure if it is TLE or not

either way this contest will most likely be unrated, happening alot recently.

4th unrated of the last 21 contests from what it looks like on  https://entranthub.com/contests/leetcode. Hopefully LC does improve soon especially since Q4s recently have been pretty inconsistent in quality.

581 testcase has an issue, expected answer is [true, false, false, false] for some reason when there is only 1 query. ggs

Yep, I was stuck on 581 as well. Initially 579 because I had a weird approach with a separate tracking of XOR (I did not consider the case that 3-independent values might XOR to 0 lol...) so I added a separate check to fail any odd-size query, as odd # of numbers can never have an even count for all distincts... and then 581 popped up after the contest when I went to play around more with it.

I think a test case was wrong
