''' | ||
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 | ||
