var square = new Rectangle(SQUARE_SIZE, SQUARE_SIZE); square.setPosition(x, y); square.setFilled(true);

However, getting the "fixed" version—where the grid perfectly alternates colors without overlapping or skipping—can be tricky. The objective is to create an

:

By understanding the common pitfalls and implementing the strategies outlined in this guide, you can successfully complete the assignment and build a solid foundation for more advanced programming challenges. Remember that the checkerboard pattern is not just an isolated exercise—it's a building block for more complex projects like game boards, pixel art generators, and graphical user interfaces.

The "fixed" code addresses these by ensuring the loop parameters match the grid dimensions precisely and that the offset logic ( row + col ) is implemented correctly.

: Failing to target exactly the top three (indices 0, 1, 2) and bottom three rows (indices 5, 6, 7). 3. The Fixed Solution Strategy

// Checkerboard logic: alternate color based on (row + col) % 2 if ((row + col) % 2 == 0) square.setColor(Color.RED); // or Color.GRAY else square.setColor(Color.BLACK);

Iterate through every row and column. Check if the row index is part of the top three ( is less than 3 ) or bottom three ( is greater than 4 : my_grid[r][c] = Use code with caution.

if ((row + col) % 2 == 0) square.setColor(Color.red); else square.setColor(Color.black);

: Using board[row][col] = 1 satisfies the CodeHS requirement that you must actually modify the list elements.

In this CodeHS JavaScript (Karel) exercise, you are instructed to create a checkerboard pattern on the screen. The pattern must:

The pattern doesn't match the required alternating structure.
