If you are getting stuck on the indentation, ensure that the inner loop is indented inside the outer loop, and the new_row.append is inside the inner loop 1.2.1 .

const ROWS = 8; const COLS = 8; const SQUARE_SIZE = 40; function start() for (let r = 0; r < ROWS; r++) for (let c = 0; c < COLS; c++) let x = c * SQUARE_SIZE; let y = r * SQUARE_SIZE; let rect = new Rectangle(SQUARE_SIZE, SQUARE_SIZE); rect.setPosition(x, y); // Apply alternating color logic if ((r + c) % 2 === 0) rect.setColor(Color.BLACK); else rect.setColor(Color.RED); add(rect); Use code with caution. 2.

Let me start writing.The following article is intended for educational purposes only. It provides a comprehensive breakdown of the exercise and its solution, but the best way to learn is to first attempt the problem yourself.**

s representing a checkerboard pattern. To solve this, you need to use and a conditional statement to decide whether to print a If you need to verify specific , port

If the entire grid prints on a single continuous line, ensure that your System.out.println() (or equivalent line break) is placed inside the outer loop but outside the inner loop.

In this approach, the two distinct rows are created first. Then, they are repeatedly appended to the my_grid to form the final checkerboard. This method relies on understanding pattern repetition rather than mathematical parity.

s using a nested loop. The most efficient way to achieve this pattern is by checking if the sum of the current row index ( ) and column index ( ) is even or odd. Python Solution

If your code is not passing the autograder, check for these frequent mistakes:

for row in range(size): for col in range(size): if (row + col) % 2 == 0: set color1 else: set color2 draw cell at (row, col)

function start() // Handle the very first row putBall(); rowTypeA(); // Loop to handle all remaining rows while (frontIsOpen()) if (facingEast()) transitionLeft(); if (frontIsOpen()) rowTypeB(); else transitionRight(); if (frontIsOpen()) rowTypeA(); // Handles rows that start with a ball function rowTypeA() while (frontIsOpen()) move(); if (frontIsOpen()) move(); putBall(); // Handles rows that start with an empty space function rowTypeB() while (frontIsOpen()) move(); putBall(); if (frontIsOpen()) move(); // Moves up to the next row when Karel is facing East function transitionLeft() turnLeft(); if (frontIsOpen()) move(); turnLeft(); // Moves up to the next row when Karel is facing West function transitionRight() turnRight(); if (frontIsOpen()) move(); turnRight(); // Standard turn right helper function function turnRight() turnLeft(); turnLeft(); turnLeft(); Use code with caution.
