916 Checkerboard V1 Codehs Fixed !link!

The outer loop tracks the rows down the vertical y-axis. The inner loop tracks the columns across the horizontal x-axis.

Because printing a 2D list can sometimes look clunky in the console, CodeHS provides a specific list comprehension line to ensure your grid prints neatly as rows and columns. However, the core of the problem lies in the of the checkerboard itself. The Secret Formula: The Modulo Operator 916 checkerboard v1 codehs fixed

: Karel never stops moving or gets stuck painting. The outer loop tracks the rows down the vertical y-axis

function start() var size = 50; for (var i = 0; i < 8; i++) for (var j = 0; j < 8; j++) var rect = new Rectangle(size, size); rect.setPosition(j * size, i * size); if ((i + j) % 2 === 0) rect.setColor("red"); else rect.setColor("black"); However, the core of the problem lies in

public class Checkerboard public static void main(String[] args) // Create an 8x8 checkerboard grid int[][] board = new int[8][8]; // Populate the checkerboard using the fixed logic for (int row = 0; row < board.length; row++) for (int col = 0; col < board[row].length; col++) // The Sum Math Trick: Even sums get 0, Odd sums get 1 if ((row + col) % 2 == 0) board[row][col] = 0; else board[row][col] = 1; // Print the grid to verify the fix printBoard(board); public static void printBoard(int[][] matrix) for (int[] row : matrix) for (int cell : row) System.out.print(cell + " "); System.out.println(); Use code with caution. Code Breakdown: How the Fix Works

: The for row and for col loops ensure you check every "cell" in your grid.
