1502. Can Make Arithmetic Progression From Sequence Easy

1/**
2 * [1502] Can Make Arithmetic Progression From Sequence
3 *
4 * A sequence of numbers is called an arithmetic progression if the difference between any two consecutive elements is the same.
5 * Given an array of numbers arr, return true if the array can be rearranged to form an arithmetic progression. Otherwise, return false.
6 *  
7 * Example 1:
8 * 
9 * Input: arr = [3,5,1]
10 * Output: true
11 * Explanation: We can reorder the elements as [1,3,5] or [5,3,1] with differences 2 and -2 respectively, between each consecutive elements.
12 * 
13 * Example 2:
14 * 
15 * Input: arr = [1,2,4]
16 * Output: false
17 * Explanation: There is no way to reorder the elements to obtain an arithmetic progression.
18 * 
19 *  
20 * Constraints:
21 * 
22 * 	2 <= arr.length <= 1000
23 * 	-10^6 <= arr[i] <= 10^6
24 *
