REMOVE PENALITY or CHANGE JUDGE FOR FIRST QUESTION (DISCSHOP)||ACM ICPC19

[kumarpratyush1]

i could feel being a student of top iit myself. solved 4 that too even without much penalty but dont even have a distant chance of qualifying

[vinodkr123]

yes, i also got two penalties because of that and also lost too much time because it was confusing.
I commented on the question raising the problem and after 20 minutes it got resolved and at that time almost 1000 teams has successfully submitted. Yes codechef should remove the penalties.

I get that many people had submitted their solution without even checking the sample test cases.That’s why they never knew that the leading zeroes in the answer need to be discarded in the output. One of my teammates made the same mistake, which cost us one penalty. We then waited until we were sure our solution was correct before making another submission.

What I don’t get is why some teams have more than one WA’s for the first problem ? It’s clear that a single WA costs you 20 minutes.Were you trying your luck or what ?

Not checking sample input output is a big big mistake. I don’t think they should consider removing penalties in that case.
It just takes 10 secs and will save you from 20 mins penalty.
Also why didn’t people ask in comments section if they had an ambiguity about leading zeroes. I think they forgot to remove leading zeroes and hence they got penalties.

They clearly show in the test case 104 gives 4 by removing 1 so clearly understood by it. Accepted in one go thanks Codechef for this problem. It made more chances for my team for the regionals.

Exactly. It’s not entirely CC’s fault. Ambiguity in the problem statement is usually cleared up by the sample test cases. My teammates don’t do a lot of CP, so it’s understandable. But what about experienced coders with a rating of 3* and above complaining about the first question ? Blameshifting is not acceptable.

And second of all, our team read the test cases, but the leading zeroes line was bit misleading too.
Everyone would have their doubts who have sound knowledge of English and grammar.

Like this one. If you have doubts, ask them in the comments. Why submit your solution and try your luck ? Also, I don’t think these people matched their code’s output with the sample test cases. If they did, they wouldn’t be in this position. And even after checking the test cases, you decided to submit the solution thinking that ‘maybe codechef judge will accept both’, you need to familiarize yourself with how these online judges work.

Frankly, they have a point.

Whether leading 0 is allowed or not cannot be cleared by the sample cases, because then there are multiple answers this case. Just because sample mentions 4 instead of 04 is not a strong argument that leading 0's are not allowed. It could be just one of the many answers which setter’s solution prints.

These things are expected to be clarified in the problem statement explicitly.
