Detailed Instructions: In this task you will be given a list of integers. You should find the minimum absolute difference between 2 integers in the list. The absolute difference is the absolute value of one integer subtracted by another. The output should be a single integer which is the smallest possible absolute distance.
See one example below:
Problem: [9, 40, -33, 12, 17, -32, 40]
Solution: 0
Explanation: The minimum absolute difference is 0 because '40 - 40 = 0' and '40' appears in the list twice. So this is a good example.

Problem: [69, 72, -95, -96, -79, -99, 35, 20]
Solution:
1
