Yashar Abbasov Re: Can anyone offer some tricky datas? [1] // Problem 1566. Triangular Postcards 3 Jan 2008 19:48 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. timus__dimus Re: Can anyone offer some tricky datas? // Problem 1566. Triangular Postcards 14 Aug 2011 02:02 ans: NO [height of postcard] sqrt(999999.75) > [height of envelope] sqrt(999999) with the bases 1 and 2.

Triangular Postcards 16 Aug 2011 14:59 This test is incorrect, sides of triangles must be integer numbers.

But it checks the case when the edges don't have to be aligned at a common vertex instead centrally.

Triangular Postcards 9 Oct 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 =) Meni Packeou Re: Dart MirzMan C++ Edition (Mirzoyan Alexey, Rybinsk SAAT) [3] // Problem 1566.

Берешь "открытку" и кладешь горизонтально стороной 900 на основание 1000 "конверта". Нарисуй на листочке, все сойдется. Edited by author 11.10.2007 13:38 Meni Packeou No subject [1] // Problem 1566.
