Question

Please finish this Assembly code.

Modify it to compute the number of elements in the deiiference of SetA and SetB (as in HW1-2) and store that number at the memory
location labeled DifferenceSize. Again, assume that SetA has eight integers and SetB has ten,
and that the two sets are “sets” in that there are no duplicate elements within an individual set but
they may be in any order.

#
# This program determines difference of SetA (always of size 8) and SetB
# (always of size 10) and stores the size of the difference.

# NOTE:
# The program should work on multiple test cases, not just the one provided.
# For full credit, be sure to document your code.

.data
SetA: .word 8, 3, -27, -60, 25, 17, 26, 9
SetB: .word 5, 17, -7, 3, -25, 27, 42, 26, 8, -60
DifferenceSize: .alloc 1

.text      
       # write your code here...

       jr $31              # return to OS

Output

Note:-

I am using MARS 4.5

I assume you want SetA-SetB count
