This happens if you try to access board[8] or board[row][8] . Remember that for an 8x8 board, indices are Alternative Approach: Alternating Rows

print_board(my_grid)
Use the graphics function to draw the rectangle at with the determined color. Example Solution Snippet
function start() var boardSize = 8; var squareSize = 50; var colors = ["red", "black"]; for(var i = 0; i < boardSize; i++) for(var j = 0; j < boardSize; j++) var square = new Rectangle(squareSize, squareSize); square.setPosition(j * squareSize, i * squareSize); square.setColor(colors[(i + j) % 2]); add(square); 9.1.7 Checkerboard V2 Codehs
To successfully implement the checkerboard programmatically, you must understand two core concepts: 1. 2D Lists (Grid Matrix)
In , you might have created a static 8x8 board. In Checkerboard V2 , the requirements typically change in one of two ways (depending on your school’s version): This happens if you try to access board[8] or board[row][8]
I’ll assume you want a concise write-up explaining the solution approach and key points for the CodeHS problem “9.1.7 Checkerboard V2.” Here’s a clear, structured write-up you can use.
This article provides a comprehensive walkthrough for completing the exercise in CodeHS. This challenge builds upon basic looping concepts by introducing nested loops and conditional logic to create a complex visual pattern. Understanding the Objective Example Solution Snippet function start() var boardSize =
To ensure your solution is correct, you can test it with these example inputs:
