916: Checkerboard V1 Codehs Fixed

In the JavaScript and Graphics-based versions of this exercise, you typically loop through a grid of rows and columns to draw squares or toggle grid states. The Problem

The instructions require modifications only to the top 3 rows (indices ) and the bottom 3 rows (indices ). The middle two rows (indices ) must remain all

This code creates a sharp, red-and-black checkerboard where the top-left square is black.

: The program must determine the correct color for each square based on its position in the grid. Common Bugs in 9.1.6 CodeHS

Inside a nested loop, use the mathematical property of a checkerboard: an element should be if the sum of its row and column indices is an even number . Example: At board[0][0] , (even), so it becomes Example: At board[0][1] , (odd), so it remains

Place a 0 (or your primary color).

If the row index plus the column index is an , place a colored block.

You must use board[row][col] = 1 . The autograder specifically looks for the = assignment operator being used on the list elements.
