So brute force or naive solutions will get partial scores right?

I think the subtasks will be designed that wayâ€¦

Yes they will be designed in that way, if your code is correct but TLEs for large inputs, you should still get a partial score.

Will editorials be posted for the contest after it ends?

Yes editorials will be uploaded within 24-48 hours of the contest ending, unless some technical issues are faced by the team

How to Solve CU4ROOM? I tried to solve it using Binary Search but my solution didnâ€™t pass it. Can anyone help me out there?

@dhairyaveera79 please move the problems to practice sectionâ€¦

move the problems to practice section , itâ€™s one day to ended the contest

It can be solved using simple greedy approach with 2 pointer technique. Assign the smallest possible room to the person who requires the the least size room.

The leaderboard is yet not updated. My score should be 700, and my rank should also be updated to 1 accordingly, but itâ€™s not yet resolved. Please do something about it. @dedsec_29 , @scyther67 , @samhat7 , @admin
