February Long challenge div2 is like math exam :/



Previously there use to be Long challenges where we have to put too much of our time to solve those questions for example JULY18B and JUNE18B and there was alot to learn from those challenges but now we can easily solve 4 to 5 on day1 itself Please make challenges such that there is alot of learning .
we couldn’t solve 4 to 5 questions on day1 in challenges like JULY18B and JUNE18B but now many can solve 4 to 5 questions in one day itself so Please make contest like that of JULY18B .

Thank you.


yes! of course
I think these questions are going to improve your Aptitude/mental ability but not much for your programming means i am not saying that math based question should not be given but there should be balance among data structure, Algorithms , Dynamic Programming and some thing like that.

There are some question which are totally math base means if you know the concept of Array and loop you can easily solve these questions so what about programming is this the right place for these question or not.
thanks to all.

I agree that some problems could have been algorithmic, like DPs and Segment Trees, or some graph theory. I really enjoyed solving ‘Art of Balance’ and ‘Guess it Right’. It’s rightly said that before the division, there was a lot more to learn from Long.

I believe 4 cakewalk problems were too many, and if users really want to improve, they should solve something they haven’t solved beore.
Overall, it was good contest in my opinion, but easy.


Don’t you people think Programming is an art of mathematics, sometimes pure math related problems are also important. Honestly speaking, for those like me solving even 4 questions in long challenge was really a challenge. But this time after solving 6 questions i really got good confidence for future problems also. Now i’ll look forward to solve most of them.


can anyone explain how to solve last two problems of this contest.


Don’t like math exams((Math exams are complicated usually!


yup !!!
it’s my first participation in long challenges on codechef
FEB19 increased my confidence (DIV2)
Most of the problems are linked with math




+1 … …


Yes ofcourse we enjoyed a lot but my question is just put some questions related to algorithms where previous long challenges had atleast 3 algo based questions for division 2 so that people learn new concepts.i don’t think these contest have such problems it just remind us geometry and probability not new algorithms and programming is all about math but we need to take care of computer fundamentals like data structures and algorithms also those are very important too


I observe one thing that every long challenge belongs to some common concept, this time it’s math turn maybe.


lol… next two were DP only(practice question for div2)… you should have tried them… I was stuck there since first day of long challenge…


Well you have plenty of platforms for improving maths skills… codechef is competitive programming platform…
Why don’t you try maths there ?


I would have understood if there were like two three problems of maths… but this time all 7 were mostly so simple… without DSA…


Problem solving and Coding is all about math
It shouldn’t be only math otherwise its not a programming question in the first place… Yes,it can include maths…


I ll have a look but problems in long challenge before January were really amazing.
we had problems like HMAPPY,INTXOR,GMEDIAN and many more they included mathematicsleft. too but were way better. Maybe some of the problem setters


Not saying that questions this time were not good. They were also good but the easiest problem in DIV1 could be replaced with something better.


this time contest was very easy imo…


Yes ofcourse programming is all about math but not in this way like formula based this will lead lot of people do cheating …yeah we need problems related bit manipulation and some algo questions atleast 2 or 3 in division 2 guys so that they can try algos rather than math


" Just making problem statement long doesn’t mean you increase difficulty. " - lol
