: fixArray(array, 1, array[1].length - 1, totalElements);
Do not swap matrix.length and matrix[0].length in your loop definitions, especially on non-square matrices (where the number of rows does not equal the number of columns).
What is the you're trying to implement (e.g., "swap rows" or "change specific characters")? Codehs 8.1.5 Manipulating 2d Arrays
Understanding 8.1.5 isn't just about passing CodeHS—it's a foundational skill for:
// Swap the element at (0,1) with the element at (2,3) int temp = grid[0][1]; grid[0][1] = grid[2][3]; grid[2][3] = temp; Use code with caution. 5. Avoiding Common Bugs ( ArrayIndexOutOfBoundsException ) : fixArray(array, 1, array[1]
Whether you need a direct solution or want to truly understand the underlying concepts, this article has you covered.
for (int row = 0; row < array.length; row++) for (int col = 0; col < array[row].length; col++) // Your logic goes here Use code with caution. 2. Using .length Correctly array.length gives you the number of . array[1].length - 1
return sum;
