# Check if the sum of indices is odd or even to alternate colors (row + col) % : current_row.append( : current_row.append( # Add the completed row to the grid my_grid.append(current_row) # Print each row to display the board my_grid: print(row) # Call the function to execute Use code with caution. Copied to clipboard Key Logic Steps Initialize the Grid : Start by creating an empty list, , which will eventually hold eight separate row lists. Nested Loops : Use a outer loop to iterate through 8 rows and an inner loop to iterate through 8 columns. Alternating Pattern Logic
// Draw the checkerboard using the stored colors for (int row = 0; row < ROWS; row++) for (int col = 0; col < COLS; col++) int x = col * SQUARE_SIZE; int y = row * SQUARE_SIZE; GRect square = new GRect(x, y, SQUARE_SIZE, SQUARE_SIZE); square.setFilled(true); square.setFillColor(checkerboard[row][col]); add(square);

Assuming you are using the (which includes acm.graphics.* and java.awt.Color ), here is the most direct and effective solution.
