      And why do you think so? The other solutions I have checked are also along similar lines so I don't see your point.

I see only 8 problems added to the contest at the time of writing this (and no challenge/approximation problem). Are you going to add the remaining 2 problems (up to 10, like in previous contests), or are these 8 problems all of them?

    No, they always have 10 problems. Sometimes the problems are added little late but Quantity of 10 is fixed as far as I know.

    The challenge problem is uploaded now. I am really sorry that it took longer than expected to add it to the contest.

Is there any reason why they always postpone uploading the full problem set and the translation in Mandarin Chinese, Russian and Vietnamese??

    There are many factors which lead to delay of some problems, one of them is the lack of proposals that codechef team receive which lead to difficulty of finding suitable problems and that will lead to late start of preparation and testing.

    Anyway, the challenge problem is already up and the last problem should be ready soon

      If you don't mind, can you share how many problem proposals CodeChef team gets on average for every long contest ? I have always been curious about this.

      Also, can someone at green level send a proposal for a problem, (If he has an idea about the problem but doesn't know how to rigorously set test cases or doesn't know an efficient solution for it) ?

      Thank you in advance

        In my opinion, can't "setting test cases" is OK (anyway, you have to know corner cases and set them by yourself), but if you want to send problem to contest, you must know its AC solution...

        BTW, I have some problems and I want to see them in some contest :) Let's wait answer from admins

        I don't have an idea on quantity of proposals.

        as far as I know, it's okay to propose idea of a problem without preparing it, but you should at least provide constraints for this problem and describe a solution that would pass those constraints. furthermore, not preparing the problem will lower your compensation.

The challenge problem really challenges the reading capability. How many years it took to write this problem?
It has 10614 characters in it :D
Probably the longest problem description ever.

    You seem very excellent reader that you could also count number of characters while reading :)

    There is a small apology disguised as a constraint. You must check it! Also, I am sorry that there was no potato for the long post.

    On a much serious note, writing a statement this long is not the hard part. The hard part is explaining what you mean and making sure that all constraints are clearly specified.

    This happens sometimes as the test cases aren't always perfect. You can inform about it by creating a post on discuss.codechef.com.
