Instead of factoring, just try to think the inverse problem... If you know sopf, can you calculate sopf[j] where j is a multiple of i?

I've also been trying the same icpc problem, and I only get TLE (lots of TLE's :cry: ). If sb find a fast algorithm please email me at txandi@gmail.com. What I'm doing now is: 1) Fill all "sure" blanks (the ones that can only be filled with a number) 2) Sort the blanks I have to fill. The first one ...

You can simplify your formula:

Code: Select all

dist = acos( sin(rad1) * sin(rad3) +
       cos(rad1) * cos(rad3) * cos(rad2) * cos(rad4) +
       cos(rad1) * cos(rad3) * sin(rad2) * sin(rad4) ) * r;

10873 - Splat, Inc.

I can't understand the sample I/O. Perhaps I've misunderstood the problem. In the first case (5 5 1 50 50 4 0 2), for example I think the output should be 9 6 6 4 and not 8 7 6 4 because: X = paintball 00000 00000 00000 00000 00000 00000 00000 00000 0000X 00000 00000 00000 00000 00000 0000X 0000X 00...

The next buoy to visit is determined by the closest buoy in the mission that has not yet been visited. In case of a tie, the buoy information that comes first in the input is given preference. It means that when you're in a place A, the next place B to visit must be the not already visited one that...

I got AC now. The input above this is ok. My (silly) mistake: There is one line after each map, ignore them. I assumed this line was empty, but I was wrong, it was full of garbage... I shoud have thought about this before wasting a lot of time debugging a correct program... In my opinion these kind ...
