conditional jump instructions.

Assignment:
Write a simple assembly language program to find the minimum, middle value, maximum, sum, and
integer average of a list of numbers. Additionally, the program should also find the sum, count, and
integer average for the negative numbers. The program should also find the sum, count, and integer
average for the numbers that are evenly divisible by 3. Do not change the data types (double-words) as
defined below.
Declare the values:

You may declare additional variables if needed. All data is signed. As such, the IDIV/IMUL would be
used (not DIV/MUL). The JG/JL/JGE/JLE must be used (as they are for signed data). You may
assume the first number in the list is evenly divisible by 3.
Note, for an odd number of items, the middle value is defined as the middle value. For an even number
of values, it is the integer average of the two middle values. The 'middle value' does not require the
numbers to be sorted.
