I wanna ask what is going on with the test cases I sent for
1099? I think I talked with Marat Bakirov and he said that
he will have them uploaded right away. Well I am sure that
they are not because if they were some solutions wouldn't
work. Please upload the cases. I don't write this as email
because it usualy gets lost with your server (or at least
the last time). If you post my cases this could stimulate
me to waste some of my time on creating even more test
cases so the problem accepts more "correct" solutions.

Btw the last contest had the best problems so far (from the
contests held at timus). Did you set so low limits for the
circle problem (1103) so that you can verify there aren't
more than 3 colinear points, or more than 3 cocircular
points in the inputs?
Btw whats the complexity of the algorithm for checking if
there are more than 3 cocircular points that you used? The
best thing i thought was O(n^3) which is actualy C(n, 3).
