| Anyone else getting WA16? | timus__dimus | 1566. Треугольные открытки | 18 авг 2011 04:00 | 2 |
Pls help me out. I keep getting WA16. Use eps = 1e-10 when checking that the points of one triangle are inside the other triangle. |
| Can anyone offer some tricky datas? | SerailHydra | 1566. Треугольные открытки | 16 авг 2011 15:36 | 9 |
Are you sure?
Can you explain, why? Yeah exactly why NO? If you put them as two triangles with two equal sides with 1000 mm long then the answer will be YES. And the bases should be 2 and 1. ans: NO
[height of postcard] sqrt(999999.75) > [height of envelope] sqrt(999999)
with the bases 1 and 2.

2.7784887979 3.6878177829 4.2
ans: YES This test is incorrect, sides of triangles must be integer numbers.
Edited by author 16.08.2011 14:59 Yes. But it checks the case when the edges don't have to be aligned at a common vertex instead centrally.

Edited by author 13.11.2007 12:13 Re: Mister Chery Dart MirzMan C++ Edition (Mirzoyan Alexey, Rybinsk SAAT) 9 окт 2007 20:22 Try this:
1000 510 510
900 900 1
Ans: YES
PS: Thanks for you code =) It helped me to get AC =) Re: Mister Chery Dart MirzMan C++ Edition (Mirzoyan Alexey, Rybinsk SAAT) 9 окт 2007 20:32 First I tried to put the second triangle to the bottom side of the first triangle ((3!)^2 ways), but it gets WA16. I don't know, why. Maybe, it was the problem with precision.
Next I combined my solution and your and get AC =) Алексей мой код дал
1000 510 510
900 900 1
ответ: "NO"
Я решил задач из высати. Я думую ещё условия ест.Помоги если сможис. No, the answer is "YES".
Сорри, но мне это по англицки просто не сформулировать. Берешь "открытку" и кладешь горизонтально стороной 900 на основание 1000 "конверта". Нарисуй на листочке, все сойдется.

I am get WA on test 6, please give me test 6 please. |
| 6 - тест! | ApriCot | 1566. Треугольные открытки | 7 апр 2008 19:40 | 2 |
Что там в этом 6-ом тесте?! |
| WA #12. My algo seems to be true... | Yashar Abbasov | 1566. Треугольные открытки | 4 янв 2008 04:19 | 1 |
I have wa 12. my algo is simple. i compare the heights and bases of triangles and print the answer. base is the side with max long. my prog passes all tests that are here as well. can you help me? where is my bug? |
| To:Admin | ScaleRhyme | 1566. Треугольные открытки | 3 янв 2008 00:34 | 2 |
Please add this test:
3 3 2
2 2 2
the ans is YES while my prev Accept program got No.Now I fix the bug but I'm sure that several Accepted author will lost AC |
| Problem "Triangular postcard" has been rejudged again (+) | Vladimir Yakovlev (USU) | 1566. Треугольные открытки | 15 окт 2007 12:41 | 4 |
Some new tests have been added. 5 authors lost AC.
Sample input #2 (as well as test #2) has been modified, now all triangles in all tests have positive area. Can this problem be solved with float arithmetics? Or must I use long integer arithmetic? Yes, this problem can be solved with float arithmetics even without epsilon-precision comparison (but it only because tests at present is enough easy) |

Edited by author 06.10.2007 17:06 Why I have lost (+) ???
My status was Accepted, but now is WA???
Is the reason sqrt(-)? Why was my first message deleted?
Was the reason using russian language or no?

Edited by author 06.10.2007 17:49 200 200 200
210 100 110
It is only 1 test with singular triangle?
Now I receive AC with code
...
if (tr.m[1]+tr.m[2] == tr.m[0]) { cout << "NO" << endl; return 0;}
...
Very strange test.
