Task: Write a short assembly code, that finds the sum of absolute differences $($SAD$)$ of all pairs

in a given array with at least two elements.

For example, if the array is $\{1,2,3,4\},$ the SAD is $|2-1|+|3-1|+|4-1|+|3-2|+|4-2|+|4-3|=10$

Your program must work with the predefined constant LENGTH and use indexed mode when

accessing array elements. It will write the SAD of all pairs to the variable called SAD. your program needs to work correctly for any array
