Answer #1

Your code is perfect.

From your code, x[3] = -4 and x[4] = 6, so y[2] should be 2 after executing the code.

I have shown you 2 screenshots to confirm that it works. The first screen is just after assembling the code before execution. 2nd screen is after execution. Before execution you can see the data segment that y[2] = 0 and after execution y[2] = 2

Screen 1 (After assembling , before execution)
