not yet, let me think a while :)

:P

You can probably push yourself as a human, then implement that in the machine. No dehumanising needed.

The reference implementation is really what I did by hand, nothing more (though quite a lot).

Would you like a hint?

That is a little bit hard for me as I have implemented algorithm that I would use if I were to solve this problem myself (pure logic).
Now, I have to forget about my human nature and start thinking like computer (to find faster solution).

You are evil man as you are turning good humans into machines. But whatever. I will do it.. your way :) Just give me some time to push myself beyond my human limits :)

Don't optimise your code. Improve your algorithm.

There is room for 8×8 skyscrapers. People have crazy fast solutions.

For now, good luck and have fun with the 7×7!

I have similar problem.
Sample test passed in 2.5s but to pass entire Kata it is much harder =/.

In fact, it is very, very hard to optimize code (meanwhile waiting for 8x8 Skyscrapers :)

Once again the guy who solved all 1kyu katas... ups sorry, all the python 1kyu katas;-)... Good work, seems to me python is your language:-)...

Second one to finish! Congrats!

small gift ;)

I could but don't think I will try until the inevitable 8x8 skyscrapers kata appears :P Ah yeah good shout! I'll give them a go once I've cracked the last couple 2 kyu I haven't done yet.

660 ms in 7x7. You can do better... ;p

By the way, you might want to do these ones too (upvoting and ranking will help them to go out of beta):

Optimizations done! Feels damn good, 3 seconds to solve all 7x7 tests and 0.4 seconds to solve all 6x6 tests too :)

Solved 6x6 yesterday but this is just crazy, optimized my test solution from 12.5 seconds to 5.2 seconds but still not enough. I'll get there, just need to figure out where to optimise next!
