Codehs Fixed — 916 Checkerboard V1

To solve this efficiently, we divide the problem into three distinct logical components:

The core challenge of the "916 Checkerboard" is not drawing the squares, but determining their color. This is where many early attempts fail. A common misconception is that the color alternates simply based on the loop counter (e.g., if i is even, red; if i is odd, black ). While this works for a single line, it fails on a grid because the first square of a new row must be the opposite color of the last square of the previous row.

This approach uses a nested loop as required by the CodeHS autograder.

t = turtle.Turtle() t.speed(0) SIZE = 50

Printing 1 0 1 0... directly will pass the visual check but fail the "You should set some elements of your board to 1" test. While this works for a single line, it

If the sum is an , leave it empty (or place an alternate color).

# Determine Color # If (row + col) is even, draw black. If odd, draw red. if (i + j) % 2 == 0: t.color("black") else: t.color("red")
