@aryanc403, you may have to wait for around 1.5 months, I got my laddus (for some challenge), during the last days of next challenge...

Hello Guys. I hope you all had a fun solving problems of November Challenge. So, time for Editorials, Editorials for problems other than RECIPES, MAXDTREE, CHEFEQUA, and BINSTR has been posted (will be available as soon as moved to public by admin). I'll try to complete these editorials too, as soon as I can. For now, I am sharing brief setter's notes for these problems.

See you on announcement page of 100th CookOff.

If someone just attempts non-scorable problems, then will the contest be rated him?

I mean if I just solves div2 problems not part of div1, will the contest be rated for me?

@admin @vijju123

@lakh are you sure about this? have you ever done this?

(02 Nov '18, 20:12) pshishod26454★

Its not rated for you, and your participation is also not considered.

(02 Nov '18, 21:35) vijju123 ♦♦5★

But it will be considered for plagiarism checks, and if caught, you will be penalized.

@admin Request to extend Long challenge by atleast 2 days
due to diwali holidays in india, most of the indian students went their home to celebrate diwali and its quite difficult to get time in between diwali festival at home. After diwali festivals, students started solving long challenge but now only 1 and half day left.

So @admin plz extend ongoing long challenge 1-2 days so that one can give full effort.
