# Print a new line after every row is finished print()
A checkerboard pattern is mathematically defined by the sum of the row and column indices. If the sum is even, the cell is one "color" ( ); if it is odd, it is the other ( Step-by-Step Implementation 1. Initialize an Empty Board 9.1.7 Checkerboard V2 Codehs
For the next row, Modulo knew it couldn't be the same, or the colors would touch. He told the second apprentice, "Start with pearl (1) instead, then obsidian (0). Repeat that four times."The second apprentice laid out: [1, 0, 1, 0, 1, 0, 1, 0] . 3. Automating the Entire Floor # Print a new line after every row
for row in 0..N-1: for col in 0..N-1: x = col * squareSize y = row * squareSize if (row + col) % 2 == 0: color = "black" else: color = "white" rect = Rectangle(squareSize, squareSize) rect.setPosition(x, y) rect.setFillColor(color) rect.setStrokeColor(color) // optional add(rect) He told the second apprentice, "Start with pearl
To solve 9.1.7 Checkerboard V2 , you need to be comfortable with these four pillars:
[Black] [Red] [Black] [Red] ... [Red] [Black] [Red] [Black] ... ...
