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.

Let me give you an example: [9, 40, -33, 12, 17, -32, 40]
The answer to this example can be: 0
Here is why: The minimum absolute difference is 0 because '40 - 40 = 0' and '40' appears in the list twice. So this is a good example.

OK. solve this:
[71, 87, 53, -98, 57, 21, 100, -10, -51, 99]
Answer:
1
