Please don’t post solutions this time. In last long challenge many ppl have uploaded solutions on youtube.

Please change it to tester from taster

I thought maybe since the theme is related to “Chef” and “Cooking” , that’s why it’s taster xD

harish_49 · January 3, 2020, 6:33am

Didn’t go that far XD

What’s the point of solving this challenge… when the solutions of major problems of last challenge(december) weren’t released… @admin isn’t your work to see all this… Just look at the way how codeforces work(today contest… editorials(of all problems) within 2 days)…

knakul853 · January 3, 2020, 5:31pm

Always love his editorials ,specially for hard problems

anon2040365 · January 3, 2020, 5:44pm

Really good problems,
Especially Chefina and Prefix sums seems good one.

hetp111 · January 3, 2020, 5:55pm

…and release it on time before discuss is filled with unofficial editorials : )

hitch_hiker42 · January 4, 2020, 4:56am

The comment section of the problem statements are quite inactive, responses take forever (if any). Though it feels good if you figure things out yourselves, it takes the time that you could’ve utilized in solving the problem. So I really hope my queries are answered before the contest ends this time.

vijju123 · January 4, 2020, 10:18am

I do not see how unofficial editorials are bad.

hetp111 · January 4, 2020, 11:57am

I never said they are bad. I am saying there’s no point of releasing the official editorials afterwards since everyone has already referred the unofficial editorials already.

vijju123 · January 4, 2020, 12:31pm

I disagree. I feel that there is a point and need of official editorials despite unofficial ones in the forum.

Can you give me some worst test cases to check whether my code is correct or not?
Problem: Equality (ISBIAS).
