It is ensured that each cylinder can touch no more than one cylinder at its left and no more than one cylinder at its right.

What cylinders is it refering to? 3 is touching 4 and 6 on the right, right?

if all the weight you're adding is to the right, your root couldn't possibly shift to the left, it could only shift to the right (or stay the same) to compensate. I can see why that is intuitive to believe in, but it is still not clear to me that it is true for all cases. can you explain some more ...

So the abs(long long) doesn't work on UVa? That's really weird! I've used it for other problems but for this one I had to hand make abs or I get WA. I guess I was just lucky in all my previous problems.......

Here's one more way: cos(a+b) = cos(a)cos(b) - sin(a)sin(b) cos(a-b) = cos(a)cos(b) + sin(a)sin(b) so cos(a+b)+cos(a-b) = 2 cos(a)cos(b). Now let a = (N-1)A, b = A, and you get the formula cos(NA) = 2cos((N-1)A) * cos(A) - cos((N-2)A) and it is clear that cos(NA) is a polynomial of degree N in cos(...
