If your code is producing a solid block of color, a misaligned pattern, or throwing out-of-bounds errors, you are not alone. This comprehensive guide breaks down the logic of the checkerboard problem and provides the clean, fixed code you need to pass the autograder. Understanding the Checkerboard Logic

Ensure your loop variables start at 0 and terminate strictly before reaching the maximum count: for (int r = 0; r < max; r++) . 3. Execution Scope Mistakes 916 checkerboard v1 codehs fixed

You need to . For example, to alternate between 1 and 0 in a pattern:

function transitionToEast() turnRight(); if (frontIsClear()) move(); turnRight(); Use code with caution. Step 3: Integrating Parity Checks What your asks for (for example, if they

Using <= instead of < in your loop conditions often causes the program to draw an extra row or column off-screen. This fails the CodeHS internal test cases, which strictly validate the total number of shape objects added to the canvas. The Logical Fix: Row plus Column Check

Here are some tips and variations to help you improve your solution: For example, to alternate between 1 and 0

: Off-by-one errors in loop conditions or canvas size calculations.

You must use board[row][col] = 1 . The autograder specifically looks for the = assignment operator being used on the list elements.
