That depends on your compiler. I use cygwin and it's %llu for me
Visual Studio 2005 also supports %llu.

### 11317 - GCD+LCM

hello,

can anyone please post some hints for the first part of the problem?
if one knows how to solve the first part, second is more or less trivial

### 11315 - Attacker

can someone please give a hint or an idea for this problem?

my idea was to rotate the plane for 45 degrees but it didn't handle the boundary constraint ( it counted fields outside the chessboard as well )

There is a solution with O(n) too. For the previous posted test, my code outputs 21341254742 6326026258 93611494 92130101 can you please tell me what do you get before you round your solutions i get: 21341254742.435440063476562 6326026258.263971328735352 93611493.600922271609306 92130100.9769803583...

Well..I tried that problem during the contest..I guessed there was a solution when (n-4)%3 == 0, you can make the sample for 4, 7, 11 and you will find that the solution follows a pattern.
