Now, the long challenge has completed. So, can someone share his approach on the problem Change the Sign?

Thanks!

Here is my approach for change the sign… I have used algorithm for finding max sum subsequence such that no two adjacent are taken at a time(not only max sum but the subsequence also)… Have a look at my solution …

@vijju123 I was in div-1 and got 107 rank will I get 300 laddus ? I set filter to India in ranklist and if 20 different rank values are considered then I should get them.

Can some one please tell me where my solution is going wrong for FAKEBS!! This is my solution. This is another solution I’ve tried to the same question. Irony is that both of them failed for the same test cases :frowning:

How long till the editorials come out?

Also, there aren’t any editorials for April Lunchtime yet. ( The links are there but they redirect to a 404 )

Where is the editorial for May LONG Challenge?

Hello all,

In view of delay of editorials, I had a discussion with @mgch and @admin , and we decided that due to issues with current Editorialist, Problem Tester (Suchan Park) will now write the editorials. I assure you that this task is at highest priority for contest admin @mgch and @admin and they will try their best to provide you guys with quality editorials of the problems.

Regards
@vijju123
