# Minimum Absolute Difference in Array

Easy
33.3% Acceptance

In this lab, you will find pairs of elements with the minimum absolute difference in an array of distinct integers. You will implement the `minimumAbsDifference` function using JavaScript ESM import/export features, which takes an array of distinct integers as input and returns a list of pairs of elements with the minimum absolute difference in ascending order.

## Problem Description

Given an array of distinct integers `arr`, you need to find all pairs of elements with the minimum absolute difference of any two elements in the array. The function should return a list of pairs which:

• `a, b` are from `arr`
• `a < b`
• `b - a` equals to the minimum absolute difference of any two elements in `arr`

### Example

Example 1:

Input: arr = [4,2,1,3] Output: [[1,2],[2,3],[3,4]] Explanation: The minimum absolute difference is 1. List all pairs with difference equal to 1 in ascending order.

Example 2:

Input: arr = [1,3,6,10,15] Output: [[1,3]]

Example 3:

Input: arr = [3,8,-10,23,19,-4,-14,27] Output: [[-14,-10],[19,23],[23,27]]

### Constraints

• `2 <= arr.length <= 105`
• `-106 <= arr[i] <= 106`

## Challenges

1. Export the `minimumAbsDifference` function.
2. Verify the return value of the `minimumAbsDifference` function for a given input.
