what a stupid problem
solution is ALL IFs
I used 3 queens for positions 2,7 7,7 2,2 and 7,2 and was failing a few test cases. Still don’t see how 2 is possible
It's always sufficient to use at most 2 queens.
For example:
1
5 3
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
2 0 0 0 0 0 0 0
0 0 1 0 0 0 0 0
0 0 0 0 2 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
And:
1
2 2
0 0 0 0 2 0 0 0
0 1 0 0 0 0 0 0
0 0 0 0 0 0 0 0
2 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0

If you are truly trying to help, you should either email this to us, or post it after the contest is over. Right now, you are just making it easier for many others to cheat, which is moronic.
These questions are so classic that I'm a bit bored.
Rocket Pack was cool beans B)
Also
MAKEIT1and other problems were also cool I think, at their respective positions. Enjoyed this contest a lot beyond the 3hrs time :)How do you solve MAKETIT1 ?
