Shopee Code League 2022 - Qualification Round

Where Can I get the final list except for emails? 

Since you can't upsolve on HackerEarth, here are the problems on other online judges:P1 - billboard: https://leetcode.com/problems/tallest-billboard/P2 - fireworks: https://codeforces.com/contest/372/problem/CP3 - connecting numbers with smaller constraints, and different input format: http://poj.org/problem?id=3207Thanks people in this forum + people in VNOI community for finding these links.

After the update at 8AM (GMT+8) today, our team rank is still not updatedTeam name: Only2Problems, solved 3 problems but in leaderboard is 0

Background: It seems solution given by problem setter has a few bad cases. I thought perhaps the post in https://www.hackerearth.com/en-us/challenges/competitive/shopee-code-league-2022-qualification-round/discussion/is-connecting-the-nu-354823c6/ was totally ignored. So I resend a post.I discuss with my teammate after the contest and get a solution O(nlogn) finally. We only need consider Intersection of line segments, while using Bipartite graph decision directly is O(n^2).For Line (li,ri) and (lj,rj), we sort segments in increasing order according to left point. That means, when i<j, li<lj. Intersection happens when li<lj<ri<rj, let j to i connect an edge.The contribution of line segment i is recorded on ri. Segment j intersects with segment i when and only when lj<ri<rj. Traverse n segments in sequence to ensure li<lj. Add each segment i (to be exact, ri) on SegmentTree.Then traversing the line segment tree in reverse order, use Segment Tree to check whether there is color conflict between adjacent edges(when current segment is black, check adjacent segment is white(or haven't been colored now), and vice versa), and then color segments. Code can be seen in https://ideone.com/cKCkYkA Blog Version for Chinese：https://blog.csdn.net/Code92007/article/details/123606684Changing input/output logic only, it passes the problem poj3207(http://poj.org/problem?id=3207), a same problem with small data range. However, it traverses segment by reverse order, instead of dfs and bfs order. I'm not sure about its correctness.Could you give proof of correctness or counter-examples? I'm very confused now.

 After the contest, we've discussed the solution of this problem with other teams that got AC on that problem. When I gave this testcase to their solution, they output "no" when there's actually a solution for it (shown in the illustration).1 4 1 2 3 2 4 3 1 4

We have two codes acceptted. But cannot see us in the leaderboard. Can you help to check it? Our team name is FreeBoBo.

This year is the second time I participate in Shopee Code League. Every time, HackerEarth has so many issues. After 2 years, the platform never improve and it is even worse than last time:No support for team participationCan't handle load at beginning of contest - took forever for us to register and start looking at statementsBroken leaderboardJudge queue too long - has to wait forever for submission to be judgedOn problem overview page, accept status takes forever to be updated.(Edit, based on comment below): No clarification system. So contestants need to ask question via Zoom.No announcement system. For example, statement of P1 was changed (to add missing constraints). However contestants received no announcement. I only know the statement changed because I randomly refreshed the page.I participate in lots of programming competition and literally no platform is as bad as HackerEarth. Can't Shopee use something else? Edit: Oh it even showed my name incorrectly :|

my friend's code has result for this test:141 2 1 3 4 3 2 4is NO , and he AC but i can find the solution for this test

Leaderboard not updating my team's rank

HackerEarth doesn't update my team problem status and leaderboard.

Please only click "Finish Test" once you are confident that you do not want to make any more changes to your codes. You will NOT be able to re-access the competition once you click "Finish Test".I want to ask where "Finish Test" button?Tks.

Leaderboard not updating my team's rank and submissions :(

Can't access the problem question

I can not open the problem by clicking "START NOW". Anyone see the problems now?
