Celebrate the new year with CodeChef’s January Long Challenge 2019 sponsored by ShareChat. This programming contest lets you tackle 8 problems over 10 days and it’s open to programmers in every country and at every skill level. The contest problem statements will also be available in English, Hindi, Bengali, Russian, Mandarin and Vietnamese.
Participants will also have the opportunity to apply for jobs at ShareChat - India’s fastest growing social network. Visit the contest link for more details.
I hope you will join your fellow programmers and enjoy the contest problems. Joining me on the problem setting panel are:
Registration: You just need to have a CodeChef handle to participate. For all those, who are interested and do not have a CodeChef handle, are requested to register in order to participate.
Prizes:
Top 10 performers in Global and Indian category will get CodeChef laddus, with which the winners can claim cool CodeChef goodies. First to solve each problem except challenge - 100 laddus. Know more here: https://www.codechef.com/laddu. (For those who have not yet got their previous winning, please send an email to [email protected])
Good Luck!
Hope to see you participating!!
Happy Programming !!
Questions are good but not as good as most of the previous long challenge problems. Interactive problems from December long challenge were interesting.
This time Questions are too easy considering for a long challenge. And many questions’s solutions are just few lines that does not match with the word “Long Challenge”.
Also I noticed that there are not different variety of questions in this month’s contest. Please put questions of different different types and topics from next challenge onwards. So that we can enjoy problem solving,thinking and debugging till full 10 days, as in previous long challenge.
Ok, let’s try. Some people complained that CC contests are implementation-only. So, this long challenge was attempt to disprove that claim. In ideas we have not many problems from other topics.
Maybe it would be good to make some voting about the type of contest. I feel that now we have a lot of problems: slow system, weak tests(if adding systests then there is almost no sense to submit solutions during the contest) cause the system is slow and not allowing to use a lot of TCs, an imbalance of the difficulty(sometimes happens), the lack of creative ideas(especially med+ problems).
Actually there is a good variety of problems in this challenge. You can try lots of advanced techniques on last 4 problems of div1. And first time I saw more than 1000 participants in div1. I’m feeling motivated now
I assume them to be distinct(can’t overlap) and I also assume that they should be A1,A2,A3 in order(not random)… (Obviously ?)
I wonder how can you mark them randomly…
You are not supposed to ask this query in discuss… you should ask it in comment section below problem statement…
i got a serious issue i was at rank 38 just 15 min before and my score was 0.482 points and now putted my best code of the ques MATCHIT and got 0.483 points but now rank is 138.
I mean seriously man guys with points 0.482 are having 37 rank and me having 0.483 points is having 138 rank.
i think there is some bug or error in checking process plz fix it asap : (
This contest was pretty good.I solved 6/8(left the challenge problem + Pizza Slice) …but there is some problem.
My point of view from Div.2–>
All the questions were based on observing some pattern and then writing the code. That’s it.Same was the case in December-Challenge except for “Color-binding Feast” and that graph-based problem.
I am really missing those algorithmic and mathematical problem(s) which ‘Codechef’ used to have in their Long Challenges and then, those were the problem(s) from which we get to learn the most.
For example,
Really? I have to disagree. Last 4 problems: some high school geometry, ad hoc graph theory, sqrt decomposition to squeeze under TLE, again sqrt decomposition to squeeze under TLE.
I agree with @meooow I didn’t solve the last two questions (because sqrt decomposition didn’t strike me :P) and didn’t enjoy solving rest of questions. As a result, I didn’t submit the challenge problem.
On a side note, last two cf rounds had pretty creative tasks.
@aryanc403 yes, @wxh010910 rejected almost all med-hard+ problem ideas I accepted & thought to use. Seems the next longs will be easier.
After jan18 I posted this comment https://discuss.codechef.com/answer_link/121277/ almost one year passed and it seems I’m unable to solve these issues… Sorry about that quote. It won’t happens again with nobody
