For some reason, I computed 678656 for the input n=17,k=1 and get WA.
But when I change it to 678856 I get AC, but I'm think 678656 is the correct answer.

If you want, you could pm me your code and explain why you think one
is correct, and the other is wrong. Thanks.

I also get 678656 now with a different slow brute force program.
I have sent in a correction.
Hopefully, it will be rejudged soon.
The contest will also be rejudged (one person tried it).
In the meantime, if you want to get AC, just change to 678856.
All the other numbers in the datafile are still corect.
Thanks sclo.

The data files have been corrected and all solutions for both the
contest and the archive have been rejudged.

"However its(queen's) powerful attack can be blocked with a Pawn, just like chess on Earth"
what does it means? can anybody explain? thanks ^^

it means the following is a valid placement: (Q is queen, P is pawn)
