#ChallengeAbsoluteDifference #Algorithm #DataStructure #Loop #Array

Consider an array of integers, arr[0], arr[1] ... arr[n-1]. We define the absolute difference between two elements, arr[i] and arr[j] (where i != j), to be the absolute value of arr[i] - arr[j]

Given an array of integers, find and print the minimum absolute difference between any two elements in the array. For example, given the array arr=[-2, 2, 4] we can create 3 pairs of numbers: [-2, 2], [-2, 4], and [2, 4] . The absolute differences for these pairs are |(-2)-2|=4, |(-2)-4|=6, and |2-4|=2 . The minimum absolute difference is 2.

Q: Define the minimumAbsoluteDifference function which has a parameter arr. It should return an integer that represents the minimum absolute difference between any pair of elements.
