Cucaracha 19 Feb 2023 16:08 After so many years, I tried my WA#27 code again. with G++ 9.2 x64 or Visual C++ 2019 x64, the same code got AC. Compilers!!! Sirko Not a word about input precision // Problem 1340. Cucaracha 1 Feb 2019 23:07 So for this test: 0 0 90 5 0 -0.00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001 correct answer is 31.4159, right?

I'm getiing WA again and again :( Edited by author 22.06.2016 19:38 Korduban [Kiev] Accepted from the first attempt! [1] // Problem 1340. Cucaracha 21 May 2005 22:12 What an amusing problem! Now it seems to be easy - in contrast to prima facie :^) Special thanks to Vorokh Sergey and Mamonov Anton, who proved correctness of my solution. And some test data input #1: 0 0 90 5 5 4.9 output #1: 28.2176 input #2: 0 0 90 5 0 -0.000001 output #2: 31.4159 wtw Re: Accepted from the first attempt! // Problem 1340.

Cucaracha 27 Aug 2008 11:49 Are you sure there isn't 3rd case when initial path is a piece of line? Especially when crumb is closer to back side of the right circle. Denis Koshman Re: If it is correct, I'll hallow your name! (-) // Problem 1340. Cucaracha 27 Aug 2008 22:15 line+arc is never necessary. At least on given tests. Sid How can cockroach reach the crump... [3] // Problem 1340. Cucaracha 18 Mar 2005 18:26 How can cockroach reach the crump if it in circle he starting running along (I mean circle which center is closer to crumb). Can he go stright ahead and then go along the circle or he has to go along other circle firstly??? I' ve tried both variants.. but i have WA#13. Dmitry 'Diman_YES' Kovalioff My solution is also WA(13) (+) [2] // Problem 1340. Cucaracha 18 Mar 2005 21:42 I've tried lots of variants of my solution... But if the optimal solution in this case is spiral, it gonna fail... BTW, here is approximately this very test after my normalization: 0 0 90 94.85 4.5 10.07 My answer is 605.5647, but it seems to be wrong P.S. My geometry has always been unbeatable, so one day I will solve this problem ;) Pavel Egorov (USU) Re: My solution is also WA(13) (+) [1] // Problem 1340. Cucaracha 6 Apr 2005 16:49 It is realy wrong Right one is 604.4120 Denis Koshman Re: My solution is also WA(13) (+) // Problem 1340.

Edited by author 22.12.2006 19:29 Denis Koshman Re: What mean... // Problem 1340. Cucaracha 27 Aug 2008 11:44 It means that no arc on a cocroach path can have radius less than R. Lines are considered as arcs of infinite radius and sharp turns are considered as arcs of 0 radius. ErOPb|4(Lesnoy. Sverdlovskaya obl.)[USU] People from USU please help the first-year student!!! [3] // Problem 1340. Cucaracha 30 Jul 2008 11:34 WA#3!!! I cann't find the mistake in my code. I don't know what is wrong! ErOPb|4[USU] Anybody please help the first-year student!!!

Cucaracha 1 Aug 2008 02:18 You got WA3 because this test was incorrect. It is fixed now. Now you have WA22 :) Maybe this test will help you: 1 1 90 1 0 0 Correct answer is 3*PI/2. Good luck! ErOPb|4[USU] Re: Anybody please help the first-year student!!! // Problem 1340. Cucaracha 6 Aug 2008 23:06 Thanks for the test, it helped me, but there are still mistakes.
