+'''
+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
