9.1.7 Checkerboard V2 Codehs !!exclusive!!

This exercise often follows a simpler, less restrictive version, requiring students to now not only create a checkerboard pattern but to structure their code according to specific, sometimes challenging, automated testing requirements.

Initialize your constants for the board size and square size. Create an outer loop that iterates through the rows.

var rect = new Rectangle(size, size); rect.setPosition(x, y);

# Define square size square_size = 50

specifically tests your ability to use logic to create a repeating, alternating pattern across the entire grid. Procedural Solution Summary The final answer is a grid where cell is odd, and

add(square);

Ensure your loop boundaries use strictly "less than" ( < ) and stop at array.length (for rows) and array[row].length (for columns). Hardcoding numbers like 8 can cause your code to fail if CodeHS tests it with different grid sizes. 9.1.7 Checkerboard V2 Codehs

: If your rows look identical instead of shifting, check your math. Simply alternating colors sequentially without accounting for the row index causes rows to align perfectly rather than stagger. Always base the color on row + col .

You need an outer loop to control the vertical movement (rows) and an inner loop to control the horizontal movement (columns). 2. Apply the Conditional Logic

You need two loops: an outer loop for rows and an inner loop for columns. This exercise often follows a simpler, less restrictive

If you are stuck on a specific error or requirement, let me know:

: Do not hardcode the loop limits as 8 if the exercise provides variable inputs. Always use board.length for rows and board[r].length for columns to keep the code dynamic.

Let's break down the solution for a basic 8x8 board. var rect = new Rectangle(size, size); rect
