It looks like you’re asking for answers or a review of something called — likely from an online coding platform (such as CodeHS, Khan Academy, or similar) where students write a program to draw or manipulate a checkerboard pattern.
Finally, the code calls:
If your board displays solid vertical or horizontal stripes instead of a checkerboard, you likely checked only row % 2 or col % 2 individually. You must add them together: (row + col) % 2 .
Top-left corner is Row 0, Column 0. Sum: 0 + 0 = 0 (Even) -> Pattern X 9.1.7 checkerboard v2 answers

To generate the correct pattern, you need a rule that determines the color based on row and column indices. The chessboard pattern relies on (evenness or oddness of a number).
"Yes!" Leo whispered, pumping a fist.

If you are currently navigating the CodeHS Java course (specifically the exercise), you have likely encountered a classic programming puzzle. This task appears in the "ArrayList" or "2D Arrays" unit, depending on the version of the curriculum. It challenges students to manipulate a grid of squares to create an alternating black-and-red (or black-and-white) pattern, similar to a chessboard or checkerboard.
The screen is divided into a set number of rows and columns (usually 8x8).
These skills are not just academic—they are the building blocks for more complex projects like game development, data analysis, and artificial intelligence.
This creates perfect alternation in both directions, mimicking a real checkerboard.
