Changed my solution and Accept Igor E. Tuphanov Let's talk [5] // Problem 1429. Biscuits 1 Mar 2006 16:32 Why there is so large discussion about easy problems and so few about interesting ones? FE, let's talk about floating point arifmetics. Did you maid eps (very small 'soft' constant) to 'soft' your calcualtions? What value of your constant? I made it 1e-12 - it vas too small, even 1e-8 was too hard. But with 1e-6 everything was O'Key. Denis Koshman Re: Let's talk [4] // Problem 1429. Biscuits 29 Aug 2008 04:16 So far I have WA13 and tried 1e-6, 1e-8 and 1e-10. All give WA13. There is a test nearby in this forum: 2 0 0 10000 9999 0 1 Edited by author 29.08.2008 16:22 Vedernikoff Sergey (HSE: EconomicsForever!) Re: Let's talk [3] // Problem 1429. Biscuits 29 Aug 2008 13:36 All the calculations can be done with exact arithmetics - you have integer numbers in the input! Denis Koshman Re: Let's talk [2] // Problem 1429. Biscuits 29 Aug 2008 14:56 I doubt integer solution is possible under given TL/ML. And 1e-8 is enough to solve the problem using double. Edited by author 29.08.2008 18:14 Denis Koshman Re: Let's talk [1] // Problem 1429. Biscuits 29 Aug 2008 16:22 I have a question - is WA13 about precision or not? Denis Koshman Re: Let's talk // Problem 1429. Biscuits 29 Aug 2008 18:13 Finally got it!!! :) WA13 is about coinciding circles, they requied different handling... Sandro (USU) Be careful! [5] // Problem 1429. Biscuits 1 May 2006 21:41 Remember that two cuts can coincide. Sandro (USU) Re: Be careful! [4] // Problem 1429.

Biscuits 29 Aug 2008 14:54 Sory, I checked it for 9999 0 1 :) For 9999 1 1 the answer is 4. I hope nobody will be hurt. any hints for this problem~~ ? [2] // Problem 1429.

Edited by moderator 25.06.2006 23:01 Denis Koshman Re: any hints for this problem~~ ? // Problem 1429. Biscuits 29 Aug 2008 04:12 I'll post my hint because it is a general approach and common theory rather than a solution for this particular problem. For 3D primitives there is Euler formula v+f-e=2 where 'v' is number of vertices, 'f' is number of faces and 'e' is number of edges (plus/minus is easy to memorize via parallelepiped, v=8, f=6, e=12, so only v+f-e=2 gives the right answer). This formula also applies to planar graphs in the form v+f-e-c=1 where 'c' is number of connected components, and outer face of planar graph is also counted. fOrgIvE Why WA 35? [1] // Problem 1429. Biscuits 16 Sep 2007 17:03 I checked all around but found nothing wrong...... help please... EvAngElIOn No one give a hint? // Problem 1429. Biscuits 13 Nov 2007 10:14 Wind of La la la To admin, n of test 22 is more than 500 in problem description. [2] // Problem 1429. Biscuits 15 Apr 2006 13:39 When the array size = 500, I got Crash (ACCESS_VIOLATION) at 22. I change the array size to 1000, and I got TLE at 24. I think that n of test 22 is more than 500 that states in problem description. Please give out the correct maximal n. Wind of La la la Re: To admin, n of test 22 is more than 500 in problem description. [1] // Problem 1429. Biscuits 15 Apr 2006 14:01 Sorry, I'm so stupid. The maximal n is correct, it's 500. Two circle may have 2 intersected point. So the array size = 1000. KAV Re: To admin, n of test 22 is more than 500 in problem description. // Problem 1429. Biscuits 15 Apr 2006 16:23 The amount of points can be much more than 1000 ;) KAV Test #22 - Bisquits [4] // Problem 1429. Biscuits 6 Apr 2006 14:15 I have WA 22 for about 30 times. I saw, that many people had the same problem - WA 22. What is the trick there? Dmitry 'Diman_YES' Kovalioff Just the first large test :) (-) [2] // Problem 1429. Biscuits 6 Apr 2006 17:14 KAV Re: Just the first large test :) (-) [1] // Problem 1429. Biscuits 6 Apr 2006 17:23 I haven't got anywhere arrays with 500 elements. Moreover, I skip N written the input (I read while there is something in the input and count). Everything is kept in vectors and it doesn't matter if N is 500 or 100... So, isn't there something special? P. S. What is the sign (-) ( or sometimes (+) ) in the caption of the message? Dmitry 'Diman_YES' Kovalioff I don't know, it was not me who created the tests. "(-)" means that there is nothing inside the message (-) // Problem 1429. Biscuits 6 Apr 2006 18:18 KAV Re: Test #22 - Bisquits // Problem 1429. Biscuits 7 Apr 2006 11:28 And those who had WA 22 - can you answer, how you overcame this problem?
