Given an array of distinct integers arr, find all pairs of elements with the minimum absolute difference of any two elements.

\n\n

Return a list of pairs in ascending order(with respect to pairs), each pair [a, b] follows

\n\n\n\n

 

\n

Example 1:

\n\n
\nInput: arr = [4,2,1,3]\nOutput: [[1,2],[2,3],[3,4]]\nExplanation: The minimum absolute difference is 1. List all pairs with difference equal to 1 in ascending order.
\n\n

Example 2:

\n\n
\nInput: arr = [1,3,6,10,15]\nOutput: [[1,3]]\n
\n\n

Example 3:

\n\n
\nInput: arr = [3,8,-10,23,19,-4,-14,27]\nOutput: [[-14,-10],[19,23],[23,27]]\n
