The round is also clashing with Leetcode biweekly contest 35. Can there be possibly any change in contest time?

hi, I am stuck at a point where i am unable to find out a way in which i can build the segment tree , that can process adding interval,removing interval and querying about the number of non-zero elements in segtree. Can anyone please provide me a somewhat detailed explaination on this. Thank you and sorry for by bad english.

According to me KNN is worth trying, since the task is same as finding the nearest neighbours with similarities ,but you can also try other unsupervised learning algos.

It should have been updated by now.but i think they will most probably be updated within 30 minutes.

When will the ratings update?

Yes, system tests are done. but i don't know why its taking time to update ratings.

According to my experience, I think it will be updated within an hour ,but can't say for sure!

This was the Hardest A i have seen till now.

I was talking about D.

oh. i got it .I was wrong.

I think your code is giving wrong answer in test case: 1 5 9 Correct me if i am wrong.

Due to actions of some of these people whole community suffers.Something should be done against them so that this is not repeated.

Problem resolved!!! Codeforces is Back.

when will the random T-shirts winners for the contest be announced?

The answer lies in practice only.since most of the AB don't require you to know much algorithms and B sometime require some knowledge of stl so if you use c++ you should give it a try and you can solve AB of previous contest until you feel comfortable in solving them.this worked for me.hope it will work for you too.
