9.1.6 Checkerboard V1 Codehs ((full)) — Trusted

The challenge is deciding when to use gray and when to use black. There is a simple mathematical trick:

rect.setColor(Color.WHITE);

Show you a more advanced way to fill the board using a single loop. 9.1.6 checkerboard v1 codehs

if (row + col) % 2 == 0: evaluates the grid position. For example: Row 0, Col 0: →right arrow Row 0, Col 1: →right arrow Row 1, Col 0: →right arrow

A checkerboard pattern relies on the parity of the coordinates. You can visualize the index sums like this: ✅ Final Result The program successfully generates an grid where every adjacent cell alternates between , starting with at position [0][0] . The challenge is deciding when to use gray

# Initialize the board board = []

If facing East, it turns North, moves up, turns West, and prepares to move backward along the row. If facing West, it does the inverse. For example: Row 0, Col 0: →right arrow

grid and populating it with a specific checkerboard pattern using nested loops and conditional logic.
