Your E$20\text{'}$s memory unit has been initialized with two arrays. The first array begins at the address

identified by the label first and the second array begins at the address identified by the label second. Each

array contains a sequence of non$-$zero integers, followed by a single memory cell containing zero. Both arrays

are the same length.

Write a complete E$20$ assembly language program to subtract the pairwise elements of each array into a third

array beginning at the address identified by the label third. In other words, your program should provide the

following behavior $($expressed in $C++$ syntax$)$:

Your program should work for arrays of arbitrary length. You do not have to store a zero value at the end

of the third array. After subtracking the arrays, your program should halt. Use correct E$20$ syntax. Write

legibly, in neat rows. You may assume that the arrays' contents and the labels first, second, and third have

been defined for you, but you must provide all other elements of the program. Your solution must use a loop.
