: The new value is the total count of all items (11 in this example). : The new value is array[2][0] + array[2][1] (9 + 8 = 17). For more detailed explanations, you can refer to the CodeHS Textbook on 2D Arrays or community discussions on platforms like Reddit r/codehs Are you running into a specific compiler error test case failure with your current code? The final value should be the total number

Treat each row as a single unit. Instead of swapping individual elements, we can swap the references (in Java) or loop through columns (in languages without pointer arrays). For more detailed explanations, you can refer to
