# Minimum Absolute Difference in an Array

The absolute difference is the positive difference between two values and , is written or and they are equal. If and , . Given an array of integers, find the minimum absolute difference between any two elements in the array.

**Example**.

There are pairs of numbers: and . The absolute differences for these pairs are , and . The minimum absolute difference is .

**Function Description**

Complete the *minimumAbsoluteDifference* function in the editor below. It should return an integer that represents the minimum absolute difference between any pair of elements.

minimumAbsoluteDifference has the following parameter(s):

*int arr[n]:*an array of integers

**Returns**

*int:*the minimum absolute difference found

**Input Format**

The first line contains a single integer , the size of .

The second line contains space-separated integers, .

**Constraints**
