    Queen Attack

In the game of chess, a queen can attack pieces which are on the same row,
column, or diagonal.
A chessboard can be represented by an 8 by 8 array.
Write a program that positions two queens on a chess board and indicates
whether or not they are positioned so that they can attack each other.
