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 fromarr
a < b
b  a
equals to the minimum absolute difference of any two elements inarr
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^{5} <= arr[i] <= 10^{6}
