Can you please tell, me the reverse of 100 ? And do we have to print leading zeroes in the answer ?? Is 00231 allowed ?
There is no response to the comment section for a long time. This question describes n in the constraints but there is no variable called n in the question.
Edit: I got a reply a few seconds ago after >1 hour and 3 comments later.

No not allowed , don’t think in terms of string …

This problem had wrong constraints throughout the contest. The constraints should have been 1\le n \le 10^5

Yoooo… All questions did… Right
Will there be any on-site round?

Sorry for any Inconvinence @anon55659401 all doubts were updated soon within first 10-15 mins as announcement. I hope you would have checked the announcements. Like codeforces, codechef doesnt send you a notification of any announcement so we are really sorry for that.
Rest how was the contest.
It would be great if you guys give us a feedback so that we may get better for our next contest which will go live in 2 months time.

And by the way @anon55659401 It was mentioned in the output format that integer value was to be printed so leading zeroes doesn’t make any sense.

I will be as polite as I can though my feelings are not good.
1)There were too many wrong submissions on that problem cuz of incorrect explanation.
- “5” and “005” both are integers in mathematics.
3)The real problem statement had no information . The question which you are looking now is the different one.
4)20 minutes before the contest ended, they changed the problem statement and added the relevant details, that is the question you are seeing now .
5)It was not even mentioned if we have to reverse the second number or not during the first 1:20 hours of the contest.
6)I could do that question in 5 minutes, but I took 45 minutes and 5 penalties due to this.
7)Contest was great, my only feedback is, that problem setter should always add at-least 3-4 lines more and explain fully clearly what the question is asking, if they want a fair contest.
8)They can check the lunchtime and cookoff questions of Codechef, how clear and complete the question is, that is all that we expect from you

Thanks, @anon55659401 for your feedback. We would surely learn from that and would be cautious about it next time. This time it was our first contest of this year (we are the new members just formed after are seniors and conducted the exam) so we would learn from it.

I tried to be polite, but now I won’t be. Time to give some tough love.
I tagged you and asked the question very early in the contest , but 2 hours went by and you didn’t reply, don’t you have the responsibility as a setter to reply a comment ?
I wish you guys improve on it as its very disappointing .
No-where, in the problem statement was mentioned that “we have to reverse both the numbers” till 20 minutes before the contest ended!! .You can see the amount of WAs due to this problem in the contest. I am not blind, I was there in the contest, and I know what was the problem statement for 1 hour,20 minutes, it would be better if you guys at-least replied as they do in codeforces. Responsibility and management are very important. I am out of this discussion now.
If these things are not taken care of next time, sadly I’ll have to report these things to Codechef 
Did an amazing job reporting my post so that community members won’t be able to see who is at fault…
When you are hosting a contest on codechef, you must be aware that thousands of programmers all over the world will participate in it. Isn’t it a big responsibility to make problem with all the clarity it can have? The problem indeed has many ambiguities. Even input is described as “first line is test cases followed by testcases, each line containg two numbers”. Just see the description other problems have on codechef. It shows that you spent a very little time preparing problem and did not even proof read it. Don’t you think it is your fault?

This isn’t exactly replying to comments on time in short contests.
Though the problem ideas were good, what messed them up were the vague problem statements. For example, in the question RPH001 a lot of people got unnecessary time penalties(including myself) as it was not mentioned whether to reverse the second string or not and whether to print the leading zeroes. Even though it is understood that the check for the leading zeroes was a considerable edge case for the question, but due to the vague problem statement, many people considered that printing 003 was the same as printing 3 as both of them are integers with similar value in the decimal number system. The problem RHSAT also had wrong constraints for n throughout the contest. Even that cost me a few unnecessary penalties during the contest. I hope that the next (and all future contests) are better than this one and the mistakes are not repeated.

You can see how the community is responding to you as of now…and I plead all of you guys to please read his this comment and give him the credit :-
"
The problems were updated within 5 mins of the starting of contest and tested correctly. Moreover the output clearly states that we expect integer format, so you can’t blame us if you yourself didn’t read question carefully.
Moreover integer of 003 is 3 so if you print it that ways it’s obviously your fault."
Yes, he is not at fault at all. We are at fault
He is the best setter Codechef could ever have.

I am sorry for the problem rhsat but we updated the constraints and rejudged the solution as soon as we found the mistake. And I believe that was in the first few mins of the contest, and we are sorry for that.
But please understand that for a setter a problem always appears to have been set from his point of view, so we got testers to check the problems but still minor mistakes got ignored which we corrected in first few mins of the contest.
