+ * 1200. Minimum Absolute Difference
+ *
+ * Given an array of distinct integers arr, find all pairs of elements with the minimum absolute difference of any two elements.
+ * Return a list of pairs in ascending order(with respect to pairs), each pair [a, b] follows
+ * a, b are from arr
+ * a < b
+ * b - a equals to the minimum absolute difference of any two elements in arr
+ *
+ * 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 <= 10^5
+ * -10^6 <= arr[i] <= 10^6
