The Attack of Queen Codechef Solution
Chef has started developing interest in playing chess, and was learning how the Queen moves.
Chef has an empty N×NN×N chessboard. He places a Queen at (X,Y)(X,Y) and wonders – What are the number of cells that are under attack by the Queen?
Notes:
- The top-left cell is (1,1)(1,1), the top-right cell is (1,N)(1,N), the bottom-left cell is (N,1)(N,1) and the bottom-right cell is (N,N)(N,N).
- The Queen can be moved any number of unoccupied cells in a straight line vertically, horizontally, or diagonally.
- The cell on which the Queen is present, is not said to be under attack by the Queen.

Explanation
Test case 1: The only cell on the board is (1,1)(1,1). Since Queen stands on this cell, it is not under attack.
Test case 2: The Queen can attack the following cells: {(1,1),(1,2),(1,3),(2,1),(2,3),(3,1),(3,2),(3,3)}{(1,1),(1,2),(1,3),(2,1),(2,3),(3,1),(3,2),(3,3)}.
Test case 3: The Queen can attack the following cells: {(1,1),(1,2),(2,2),(2,3),(3,1),(3,2)}{(1,1),(1,2),(2,2),(2,3),(3,1),(3,2)}.
Test case 4: The Queen can attack the following cells: {(1,1),(1,2),(2,1)}{(1,1),(1,2),(2,1)}.
