      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.
