CodeHS 9.1.6 Checkerboard v1: FIXED & WORKING! Struggling with the logic for the Checkerboard problem in Python? I finally got the

  1. The "Striping" Error: Failing to offset the rows, resulting in vertical columns of single colors rather than a checker pattern.
  2. Coordinate Calculation Errors: Forgetting that graphics coordinates start from the top-left corner (0,0) and increase downwards and to the right. A fixed script carefully calculates x and y by multiplying the loop counters by the square size.
  3. Off-by-One Errors: Looping one time too many or too few, leaving a gap or drawing outside the canvas.

Verification: The middle rows (indices 3 and 4) are skipped by the if statement, ensuring they remain empty as requested. Common Pitfall 916 checkerboard v1 codehs fixed

The Fixed Solution (Java Version – CodeHS Graphics)

CodeHS often uses a custom GraphicsProgram class. Here is the correct, working, fixed code for 9.1.6 Checkerboard (v1) in Java: CodeHS 9

Now, loop through the rows and columns. According to the instructions, you need 1s in the top three rows (indices 0, 1, 2) and the bottom three rows (indices 5, 6, 7). To get that alternating checkerboard look, use the modulus operator The "Striping" Error: Failing to offset the rows,

C. The Color Logic ((i + j) % 2)

This is the mathematical trick to the checkerboard pattern.

Nested Assignment: The inner loop (for j in range(8)) goes through every column in those specific rows and changes the value from 0 to 1.
