Many students try to use (i + j) % 2 to create a "true" alternating checkerboard pattern. While that is how real checkers look, specifically asks for solid blocks of 1s at the top and bottom with a gap in the middle. To build a checkerboard, you have to tell
Now, loop through the rows and columns. According to the instructions, you need 1s in the top three rows (indices 0, 1, 2) and the bottom three rows (indices 5, 6, 7). To get that alternating checkerboard look, use the modulus operator Now, loop through the rows and columns
