ответьте на вопрос:
допустим есть цилиндр с размеромами: 1 на 1000
и отверсие в стене размером 2 на 4,
можно ли нарезать мелкими лоскутками цилиндр на размеры 1 на 2, таких отрезков понадобиться 4 штуки, подобный ход удовлетворяеет поставленной задаче ? The sample input shows that 234 3456 is "too small" to cover 314 x 314. а в чём тогда моя ошибка ? Никак не могу пройти тест 4. В отсутствии пространственного воображения. Вы хоть намекните в чем смысл правильного решения, а то мне эта задача спать не даёт, хотя бы вышлите мне тест 4 по возможности as i understand u can rotate cylinder почти правильно сказал предыдущий автор. нужно поворачивать боковую поверхность вокруг центроида, и если её площадь "захлёстывает" прямоугольное отверстие, тогда "Block the hole"

Try this one:
1 1000000
1
1001 1000
Really right answer:
Block the hole
And the problem can be solved in integer numbers. thanks. it helped me a lot.

May I to bend the cut cylinder? Errors of calculations - reason of mistakes :) |
| WA24 and WA30 | Michael Plusnin (USU) | 1919. Titan Ruins: Transformation of Cylinders | 5 Nov 2012 14:48 | 1 |
If you have WA24 then swap(Li, Hi), and if you have WA30 use aspect ratio in a similar triangle)) |

WA#4 QWERTY 20 Oct 2012 14:07 the problem seems to be very easy but idk, i have WA#4 too Same for me, fails at 4. Please double check. Re: WA#4 ...†.†.†... Stigius ...†.†.†... 20 Oct 2012 15:38 There are many fails on test 4. But it is absolutely correct, both test and answer were checked by hands multiple times. Look for error in your code.

Take a look at the sample inputs again. Re: WA#4 Oracle[Lviv NU] 21 Oct 2012 21:25 I've checked my formula with both kinds of formulas given in this article: http://www.jstor.org/discover/10.2307/2691523?uid=3739232&uid=2129&uid=2&uid=70&uid=4&sid=21101178420913 (if someone is interested in full version of article - mailto Oracle@acm.lviv.ua) I use BigInteger in Java - should be no precision issues. Results are the same for all rectangles with 1 <= sides <= 100 and for about a billion random test cases with 1 <= side <= 1000000. And still WA#4((( Is it definitely correct? Now I wonder if the problem is exactly in checking if one rectangle fits into others? Or I've missed something? Re: WA#4 Oracle[Lviv NU] 22 Oct 2012 02:20 Sorry for complaint. Seems that tests are correct - I've misunderstood the statement. |

Have you used any formula? or some sort of binary search?
