Inside the nested loop, use an if-else statement paired with the modulo operator to check if the coordinates add up to an even or odd number. 3. Assign the Values

: Avoid manually typing out all 64 values. The exercise is designed to test your mastery of loops. specific error message you're seeing, or should we walk through the print_board function

Alternatively, the same logic can be written in a slightly different but functionally identical way: 9.1.7 Checkerboard V2 Codehs

: Every cell in a 2D array is defined by its row index ( r ) and column index ( c ).

What of CodeHS are you using? (Python Tracy, Python Graphics, or JavaScript?) Inside the nested loop, use an if-else statement

To complete this exercise, you must master three core programming concepts:

If you are still having trouble with the specific syntax of your language (like Java or Python), I can provide more tailored examples.

Copy the JavaScript solution above, run it in your CodeHS IDE, and watch the red and black grid appear perfectly. Then, experiment by changing BOARD_SIZE to 800 – and watch how the entire program adapts without any other changes. That is the power of writing flexible, "V2"-quality code.
