OK. Thanks. I'll try some interpolation methods to solve this system

Help! Need a LITTLE help. I have got TL in problem 107 (about cats and hats). Maybe my algorithm is really slow?

I present height of initional cat as prime numbers degrees. After than finding all possible n's

[pascal]
program zzz;
var i,j,k,m,s,min,gcd : longint;
h,num,l,sum,r,n,t : int64;
p,x ...

Actually, I have tags. It just didn't copy.

Thanks, I'll look better on my floating operations. But I use EPS ans all like this.

Please, help me. I always get WA in this problem. My algorithm:
1. Make convex hull with Graham scanning for each kingdom
2. For each kingdom count it's square
3. For each missle enable kingdom (or no kingdom)
4. For all enabled kingdoms sum their square.

May be, that sms wrong with:
1. When missle ...
