916 Checkerboard v1 Codehs Fixed

The 916 Checkerboard problem on CodeHS is a classic challenge that requires creating a checkerboard pattern using a loop. Here is a fixed and well-documented solution:

Why CodeHS Wants You to Learn This

The checkerboard problem isn’t just about drawing a pretty pattern. It teaches: 916 checkerboard v1 codehs fixed

Ensure your for loop conditions use < SQUARES_PER_SIDE and not <=. Using <= will attempt to draw a 9th row/column, which usually breaks the layout or triggers a "limit exceeded" error in CodeHS. 916 Checkerboard v1 Codehs Fixed The 916 Checkerboard

✅ If it’s Python with Turtle (Tracy):

import turtle

Finally, pass your completed grid to the provided print_board function to display the result. Final Output Structure Row 0, Col 0 → 0 % 2


The autograder requires you to use an assignment statement (e.g., board[i][j] = 1). You should loop through the rows and columns, checking if the row index i is in the top three (0, 1, 2) or the bottom three (5, 6, 7). 3. Implement the Print Function


    

  • Row 0, Col 0 → 0 % 2 = 0 (even → red)
    • 

  • Row 0, Col 1 → 1 % 2 = 1 (odd → black)
    • 

  • Row 1, Col 0 → 1 % 2 = 1 (black)
    • 

  • Row 1, Col 1 → 2 % 2 = 0 (red)

Testing Your Solution


    

  • Run the code; you should see a perfect 8x8 checkerboard.
    • 

  • Verify top-left is red.
    • 

  • Verify no gaps or overlaps.
    • 

  • Check that row 1 starts with black.
