Of course
It's  n queens puzzle
Solution can be found in wikipedia
I got AC now. It is solvable without random. There is a certain algo for placing the queens. Look wikipedia for example.

I agreed with you.To use random to don't know!
But in wiki algo named as heuristics? Why it not a theorem?
I do't understand.
random FOREVER - 0.21
I think that the matter not in wikpedia algorithm
but in manner of thinking that help us to produce
right algorithm quickly during context
From this position random is more perspective
Or problem must be understood in some standard way.

0.21 with random while 0.1 with O(N) wiki solution? HOW?
