WA#25 any hints? | zwqzwq | 1199. Mouse | 22 Sep 2021 17:21 | 2 |
I've got AC My heap was so small...(Could anyone talls me why 400 is unenough?) Edited by author 22.09.2021 17:55 Is there any special test? |
a question | LX&R Bacherikov | 1199. Mouse | 12 Aug 2021 06:42 | 4 |
Can the mouse go under the furniture? I mean, can it's way cross the polygons? I didn't solve it. But I think mouse CAN'T cross the polygon. If i think that mouse can go under furniture get WA3. If can't, get WA10 at the moment. So probably mouse can't go under furniture. I think it can't. I got WA3 if it can go under the furniture. But I got AC if it can't. Sorry,my English is very bad. |
600 lines of code to get wa21 :( | Martin_fmi | 1199. Mouse | 3 Dec 2017 20:28 | 4 |
Hi everybody, After a lot of testing I have wa21 ... Is there anything spacial about this test case ? Thanks in advance. Edited by author 18.07.2009 22:28 Yes, be sure you will not output more than 1000 vertices. |
WA #30 Any hints? | Baruvka | 1199. Mouse | 12 May 2014 23:24 | 2 |
Hint #1: The mouse or the cheese can be less than 10cm from the polygons Hint #2: Be careful of your first segment from the mouse or the last segment from the cheese. If you do not check correctly, they might cross a polygon. For example, think of the case of a very thin rectangle with the long side called A and a mouse that is less than 10cm from the rectangle. You have to make sure that the mouse runs to side A not the side opposite to A. |
If two consecutive points in your output coincide, you get WA. | crdp | 1199. Mouse | 21 Apr 2013 20:22 | 1 |
Which is strange, since everything else is allowed in output. |
some tests | Erop [USU] | 1199. Mouse | 19 Apr 2012 15:14 | 3 |
-0.5 0.5 1.5 0.5 1 4 0 0 1 1 0 1 1 0 0 0 3 0 1 3 1 50 1 -50 2 0 first test is incorrect. see : The furniture is a set of convex polygons. Here says nothing about order of vertices, so test is correct However, if I do not sort the vertex by angle, I don't lost AC |

Some hints | Martin_fmi | 1199. Mouse | 21 Jul 2009 05:41 | 1 |
1) print 0 instead of -0 2) print 7 digits after decimal point 3) One can use Dijkstra over shortest segments between two polys ( without having to check for any intersections at all ). |
Test 13 WA | EarthShaker | 1199. Mouse | 23 Mar 2009 06:58 | 1 |
Is there anyone who can help me with test#13? |
I want to know test8...or who give me some tests.. | данные | 1199. Mouse | 9 Mar 2009 16:36 | 2 |
I have passed all tests made by myself..but still wa8. (When my program was incorrect and with a lot of bugs..it began wa8... and now still... |
Why wa 15?????????????????????? | dejiyu | 1199. Mouse | 18 Dec 2008 17:53 | 1 |
I always get WA on 15 Can anyone tell me why |
it's so faint | yuhch | 1199. Mouse | 10 Aug 2008 19:49 | 3 |
printing 4 or 5 or 6 fractional digits will all get wa on some test cases. but when i try to submit the programme with printing 7 fractional digits, i got ac...... Edited by author 03.09.2007 06:09 Thanks you a lot! I tried 4, 5, 6 digits but had WA#17, WA#21, WA#8 correspondingly. Strange, isn't it? After reading your post I tried 7 and got AC! I think there is problem with checker |

#input 0.0 0.0 2.0 0.0 0 #output 3 0.0 0.0 1.0 0.0 2.0 0.0 This output is correct, isn't it? |
