On a standard chess board with (8 * 8) squares, a chess piece starts to move from the lower left corner, which we shall label as square (1 * 1 This piece is allowed to move only upwards or rightwards. At any point, the piece cannot move downwards, leftwards or diagonally, e.g., from square (2 * 3), the piece may go towards (3 * 3) or (2 * 4) but not any other direction. If this piece continues to
