You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

[9, 40, -33, 12, 17, -32, 40]
Solution: 0
Why? The minimum absolute difference is 0 because '40 - 40 = 0' and '40' appears in the list twice. So this is a good example.

New input: [-80, -89, -100, -44, 42, -77, 44, 9, 74, -91]
Solution:
2
