Before submitting, test these cases manually: 9.1.7 Checkerboard V2 Codehs
The goal of Checkerboard V2 is to create a grid-like pattern of "markers" or "beepers" on a canvas of any size. Unlike the first version, V2 often requires the program to be dynamic—meaning it must work whether the grid is for (int row = 0
Many CodeHS versions first ask for a text-based version using nested loops. row++) for (int col = 0
: Each square's x position is col * SQUARE_SIZE and its y position is row * SQUARE_SIZE . The Code Solution (JavaScript/karel) javascript
Let’s assume the following constants (typical in CodeHS):
