9.1.6 Checkerboard V1 Codehs !full! -

First, you'll need an empty list to hold your board.

Here is a standard way to write the program:

if the prompt specifically requests them, as simply printing the pattern without storing it in a grid may cause errors. Typical Pitfalls Incorrect Function Placement : Defining the print_board function inside another block or incorrectly indenting it. Missing Middle Rows 9.1.6 checkerboard v1 codehs

while (frontIsClear()) move(); if (startWithBeeper) // Alternate pattern: after moving, we want opposite // Better approach: move, then if column index is even/odd // But simpler: use a counter

Alternatively, if you want a more visual representation: First, you'll need an empty list to hold your board

This handles the alternating start position needed for a checkerboard. 5. Tips for Success and Debugging

To touch every single square on the board, you need two loops. The outer loop iterates through the ( ), and the inner loop iterates through the columns ( ) for each of those rows. 3. Apply Alternating Logic The outer loop iterates through the ( ),

for (let row = 0; row < 8; row++) let rowArray = []; for (let column = 0; column < 8; column++) row > 4) if ((row + column) % 2 == 0) rowArray.push(1); else rowArray.push(0);

Crucial step: The if (frontIsClear()) move(); inside the loop handles the spacing. putBeeper(); is used to create the alternating effect. repositionToNextRow() Function This function manages the "checkerboard" aspect. It checks which way Karel is facing.

The code uses two loops. The outer loop ( for row in range(8) ) iterates through the 8 rows. For each row, it creates a new, empty list ( row_list ). The inner loop ( for column in range(8) ) then iterates through the 8 columns in the current row.
