Please help me with the code, I keep getting an "program timed out" message:

SUBI X$3,$ X$19,$ #$2$

loop:

CBZ X$3,$ end

B loop

end: Write a program to populate an array with Fibonacci numbers. The Fibonacci sequence begins with $0$ and then $1,$ each following number is

the sum of the previous two numbers. Ex: $0,1,1,2,3,5,8,13.$ Assume the size of the array is always at least $1.$ Use the $\text{'}+\text{'}$ button under the

Registers display to store the size of an integer array in X$19$ and the address of the first element of the array in the memory in X$20.$

Ex: If X$19$ and X$20$ are initialized in the simulator as $5$ and $5000,$ the data memory starting at address $5000$ will contain:
