# Minimum Absolute Difference in Array

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

- Export the
`minimumAbsDifference`

function. - Verify the return value of the
`minimumAbsDifference`

function for a given input.
