function start() var squareSize = 50; var numRows = 8; var numCols = 8; for (var row = 0; row < numRows; row++) for (var col = 0; col < numCols; col++) var x = col * squareSize; var y = row * squareSize;
The most common "non-fixed" issues students encounter:
The pattern doesn't match the required alternating structure.
System.out.print(array[row][col] + " "); prints elements of the same row side-by-side with a space.
You need to . For example, to alternate between 1 and 0 in a pattern:
The primary challenge lies in the alternating pattern. It cannot simply alternate every single step, because when a row ends, the next row must start with the correct alternating value to create a grid pattern rather than vertical stripes. The Mathematical Logic
The color must switch based on both the row and column index to create the staggered effect. The Logic Behind the Fix
Before we dive into the fixed code, let's discuss some common issues that students face when working on this problem:
