I think you are not evaluating all the possible sums involving the elements of the sequence, so you need to change the algo. Try this input:

4
1 3 5 8

Your output is:
Case #1: 1 3 5 8
This is an A-sequence.

And should be:
Case #1: 1 3 5 8
This is not an A-sequence.

Unfortunately, there is an input where the value 1003 appears. I have already seen the input of this problems many times, but I could only see this error now :(

I will try to fix this error and to send the new input to UVA's site.

I am sorry!

When I decide whether two slopes are the same, I allow an error of 1e-14. It is OK. I am putting some more test cases: INPUT 10 0.3 0.5 0.0 0.9 0.2 0.8 0.4 1.0 1.4 0.6 0.4 1.0 1.7 0.7 12.5 3.2 0.1 15.7 3.3 4.6 2.3 0.5 2.2 3.1 333.6 1.4 0.8 0.6 2.0 0.9 1.3 1.9 0.1 1.4 0.0 0.7 0.0 0.7 1.6 1.0 0.1 0.1...

I friend mine also got AC in the problem 190 but he was getting WA in this problem. When we tested his program it failed in this input: 0.7 1.0 0.9 0.2 0.1 0.2 The answer should be: The equidistant location is (0.5, 0.5). He was getting something like (nan, nan) But I think it is a little bit diffic...

During the contest the explanation about the -0.0 was given, but it is really missing now :)
I will try to change the problem description and send it to the UVA.
I got AC too :)

Hi! During the contest, we changed the problem description, so a answer (-0.0, 2.0) should be (0.0, 2.0) and the output should not have a coordinated -0.0. I compared the outputs and I think this is the problem, look the cases below: 2 0.1 1.2 1.3 0.4 0.2 1.2 0.0 0.8 0.6 2.4 0.9 1.6 The equidistant ...

So, I think we have a problem now :) I will post some test cases here, so we can compare our answers: INPUT 10 0.3 0.4 0.3 0.4 1.1 0.7 2.1 23.4 5.9 0.3 4.5 -2.0 1.0 0.0 0.2 0.8 0.1 0.9 8.2 -1.7 5.4 3.0 -4.0 15.1 7.2 3.5 5.2 9.3 0.7 8.2 -7.2 -3.4 6.3 9.7 -9.0 5.4 1.9 8.4 0.4 1.9 0.4 1.9 8.1 -0.2 0.5 ...

I sent the special corretor program to UVA this Monday (08/30). I think they are a little bit busy now, so lets wait a few days and they should rejudge the submissions in this problem :)

Hi! I am one of the problemsetters of this problem. As during the contest we noted that nobody was getting accept in this problem, so after the contest I took some source codes from people in our university and changed some inputs which can produce a float point error. So after this we were expectin...

Hi, everybody!!

I tried to correct the problems during the contest, but occurred a problem with the mail service at UFRN, and I did not receive any question and I think the messages I sent did not arrived.

We are fixing the errors now and I will send the corrected version.

Re: 10061 WA

Hi, mido! I think your mistake is when you are trying to find how many trailing zeros the factorial has in the base b, the other part is ok :) Try this: Input 1000000 798 1000000 799 Output 55553 1917886 21737 1917527 Your program's output was different of the my accept's problem output.
