 So if you are told the white queen is at `c5` (zero-indexed at column 2, row 3) and the black queen at `f2` (zero-indexed at column 5, row 6), then you know that the set-up is like so:
 
-```text

 You are also able to answer whether the queens can attack each other.
 In this case, that answer would be yes, they can, because both pieces share a diagonal.
