In the score based ranking system(in Long Contests), whose name appears first in case of ties?? I know it doesnt matter as ranks are similar, just asking out of curiosity coz its neither alphabetical wise nor rating wise.

Okay, I see the issue. Send them a screenshot of your payment (the one with UTR number as well). That will safeguard you against ALL such issues, and will be your proof that you did payment on time [hence they will HAVE to accept.]

Most probably, the delay is expected, but yeah, do take the precaution and send them a screenshot. Hope your issue gets resolved soon :slight_smile:

EDIT: I suspect that the delay is because 15th Oct was the last date. If they’re saying that it will take 3-4 days, the I think its ok, there shouldnt be any issues. Just make yourself “Safe” and “foolproof” by sending a screenshot as well. I have heard it worked very well (I got accepted in an hour after sending the screenshot). The thing is, there can be mistake while typing your UTR number, or perhaps what you copy-pasted isnt the UTR number but something else (like reference number etc.). To safeguard against these fallacies, its better to send a screenshot.

The problems in the above contest are copied from codeforces and hackerrank.

Even problem statments are not changed, so simply googling the statement would fetch you the code.

I am not expecting comments like “a honest coder would not copy” and statements like that.

Thank you.

Can someone explain what WA means for executing the codes for the contest. I won’t ask for help with the code. I just want to know how the competition works and how does the code execution take place for checking my answer submission. Thanks.

Would it be possible for the author of CHEFNIL (or somebody else) to share the piece of code that is used to calculate the score of a solution?

I’m asking for this because I wrote a program which generates two possible solutions, computes the sum of points for both, and outputs the one with a larger sum. When I change the program to output just the first of those solutions (and ignore the second), the score of my submission goes up, and I can’t make sense of why this is happening.

Is it legal to ask questions related to codeforces problem set (practice) on codechef?
As both are coders platforms! Initially i started coding for the first time at codechef but was scared so someone suggested me solving on codeforces and i feel more comfortable there because you can see your failing test cases there.

65

I have a Question. If you are topmost coder of Codechef but you have 0 karmapoint then can you ask question or Not ? Is it fair to decide only according to karmapoints and not your rank and rating?

66

First off thanks for doing this, because I have questions. How do I get better at understanding the problems? I am doing beginner and just read the problem and want to claw my eyes out because I have no clue what they are asking. Is there a trick to getting better at it?
