You need to . For example, to alternate between 1 and 0 in a pattern: 916 checkerboard v1 codehs fixed
In the 9.1.6 exercise, the goal is to write a Python function that creates or manipulates a 2D list (a list of lists) so that it resembles a checkerboard. The board typically consists of alternating 1s and 0s, mimicking the black and white squares of a standard checkerboard.
If you’ve landed on this article, chances are you’re stuck on the problem in the CodeHS Java (or sometimes JavaScript Graphics) course. You’ve tried writing the code, but the checkerboard isn’t rendering correctly—maybe the colors are wrong, the rows aren’t alternating, or the squares aren’t aligned. function start() var squareSize = 50; var numRows
The problem statement is straightforward: create a 8x8 checkerboard with alternating black and white squares. Sounds simple, right? However, many students struggle with this problem, especially when it comes to implementing the solution in code.
function start() while(frontIsClear()) paintRow(); if(frontIsClear()) moveToNextRow(); If you’ve landed on this article, chances are
This is the "aha!" moment for the assignment. It teaches that patterns in computer science are often mathematical. By checking if the sum of the coordinates is even or odd, the code automatically creates the staggered pattern required for a checkerboard, regardless of the grid size.

Creating a checkerboard pattern is a classic challenge in programming education. In CodeHS, the exercise tests your understanding of nested loops, two-dimensional (2D) arrays, or grid manipulation, depending on your language track (Java or JavaScript).
var WIDTH = 400; // 400 / 8 = 50px per square (perfect) var ROWS = 8; var squareSize = WIDTH / ROWS; // Results in integer 50
