I wonder how to make nlogn algorithm for this problem!
Can you explain more? (I know set<> in STL, but I can not get approach to make it nlogn).

11017 - A Greener World

Is there a way to apply pick's theorem?
If not, what should be done? sweeping?
And, can I map everything to a normal grid before starting?

I do not know why all explanations are "encrypted" ! Is it forbidden to post a complete explanation here? Here is a complete explanation: 1) Get the 8 corners of the bounding box of the points. 2) For each corner, get the nearest point to it (in tie, choose any). 3) For each of these 8 points, compu...

Help me please!

I get TLE for this problem. How to make the whole state in ONE integer? I am using 4 integers. And I do not think that I will pass even if I do this. I made meet in the middle attack as described, but it takes a long time also for number of steps = 6 or 7. I am making BFS and I do not generate anyth...

I agree with you. Although I have known the algorithm to make it work, I do not know why it works. I thought of a lot of time.
I would like that someone who understands this problem well to explain it to us. (Why it works, and what is the way of thinking that leads to this solution).
Thanks a lot.
