Debugging CodeHS 9.1.6 Checkerboard v1: The Complete Fix Guide
If you only move left-to-right, you cannot create a checkerboard. Karel must turn around at the end of each row.
This will pass the CodeHS check.
# Inner loop for Columns for j in range(COLS):
The checkerboard problem isn’t just about drawing a pretty pattern. It teaches:
According to the official instructions for 9.1.6 Checkerboard, v1 , the grid is structured with the top three rows and the bottom three rows filled with an alternating pattern of 1 s and 0 s. The middle two rows are left completely blank, filled entirely with 0 s. The final board should have a structure that looks like this:
Example structure (not exact solution):
: Avoid hardcoding numbers like 8 inside your loop constraints. Always use board.length for rows and board[row].length for columns. This makes your code adaptable to any grid size.
