1502 - Can Make Arithmetic Progression From Sequence\. Easy A sequence of numbers is called an **arithmetic progression** if the difference between any two consecutive elements is the same. Given an array of numbers `arr`, return `true` _if the array can be rearranged to form an **arithmetic progression**. Otherwise, return_ `false`. **Example 1:** **Input:** arr = [3,5,1] **Output:** true **Explanation:** We can reorder the elements as [1,3,5] or [5,3,1] with differences 2 and -2 respectively, between each consecutive elements. **Example 2:** **Input:** arr = [1,2,4] **Output:** false **Explanation:** There is no way to reorder the elements to obtain an arithmetic progression. **Constraints:** * `2 <= arr.length <= 1000` * -106 <= arr[i] <= 106
