9.1.6: Checkerboard V1 Codehs

set canvas size (e.g., 400 x 400)
set number of rows/cols = 8
square_size = canvas_width / 8
for row from 0 to 7:
for col from 0 to 7:
x = col * square_size
y = row * square_size
if (row + col) % 2 == 0:
color = RED
else:
color = BLACK
draw square at (x, y) with size square_size, fill color

If you are working through the CodeHS Java course (specifically the "9.1.6 Checkerboard v1" problem), you have likely encountered a classic programming challenge: creating a checkerboard pattern. This exercise is a rite of passage for learning nested loops, conditional logic, and graphical object placement.

In this article, we will break down exactly what the 9.1.6 Checkerboard v1 assignment asks for, how to approach the logic, and provide a fully commented solution. set canvas size (e

Example (pseudocode):

for r in 0..7:
    line = ""
