9.1.6 Checkerboard V1 Codehs //top\\ May 2026
In the CodeHS 9.1.6: Checkerboard, v1 exercise, the objective is to create an 8x8 grid where the top three and bottom three rows contain alternating 1s and 0s (representing checker pieces), while the middle two rows consist entirely of 0s. The final result should look like this:
To create the in CodeHS, you need to use nested for loops to place circles in a grid pattern . 🏁 Core Logic The goal is to create an grid of circles. The outer loop controls the rows (vertical movement). The inner loop controls the columns (horizontal movement). The spacing is determined by the radius of the circle. 💻 Solution Code javascript
# Determine the color based on the sum of row and col indices # If the sum is even, it's one color; if odd, it's the other. if (row + col) % 2 == 0: square.set_color(Color.black) else: square.set_color(Color.white) 9.1.6 checkerboard v1 codehs
If you want, tell me which language or CodeHS API (console vs. graphics) you're using and I can produce a ready-to-run solution.
This exercise focuses on using nested loops modulus operator In the CodeHS 9
Core observation: parity (even/odd) of row+column determines which symbol to place.
