Once you've mastered "Checkerboard, v1," you can challenge yourself further:
for row in range(8): # Temporary list for the current row current_row = []
Using the parity rule (r + c) % 2 determines cell contents and yields a simple, provably correct O(n^2) algorithm. The provided textual and graphical templates adapt to typical CodeHS environments. If you supply the exact CodeHS problem text or target language/API (e.g., Java, JavaScript, CodeHS turtle), I will produce a tailored solution and classroom-ready explanation matching that context. 9.1.6 checkerboard v1 codehs
Starting with a clean slate of zeros. 3. Step-by-Step Solution Strategy Here is how you can approach the coding problem logically: Step 1: Initialize the First, create the
In this specific CodeHS exercise, you typically edit the file named Checkerboard.java . You are expected to fill in the logic inside the nested for loops to set the color of the Rectangle objects stored in a 2D array.

In this article, we will break down exactly what the 9.1.6 Checkerboard v1 assignment asks for, how to approach the logic, and provide a fully commented solution.
The secret to a checkerboard is simple math. To determine if a cell should be "colored" or "empty," you look at its row and column indices:
To create the offset pattern, look at the coordinates of the grid indices (Row, Column): Row 0, Col 0 →right arrow Color A (0 + 0 = 0, Even) Row 0, Col 1 →right arrow Color B (0 + 1 = 1, Odd) Row 1, Col 0 →right arrow Color B (1 + 0 = 1, Odd) Row 1, Col 1 →right arrow Color A (1 + 1 = 2, Even) Starting with a clean slate of zeros

In "9.1.6 Checkerboard, v1," you are told that in the next three exercises, you will be working towards creating a program that stores numbers corresponding to checkers pieces on a board. Our ultimate goal here is to make a grid that stores 1’s and 0’s, such that a 1 represents a checker piece and a 0 represents a blank square.
