<p>The <strong>distance of a pair</strong> of integers <code>a</code> and <code>b</code> is defined as the absolute difference between <code>a</code> and <code>b</code>.</p>
|
|
|
|
<p>Given an integer array <code>nums</code> and an integer <code>k</code>, return <em>the</em> <code>k<sup>th</sup></code> <em>smallest <strong>distance among all the pairs</strong></em> <code>nums[i]</code> <em>and</em> <code>nums[j]</code> <em>where</em> <code>0 <= i < j < nums.length</code>.</p>

<p><strong class="example">Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [1,3,1], k = 1
|
|
<strong>Output:</strong> 0
|
|
<strong>Explanation:</strong> Here are all the pairs:
|
|
(1,3) -> 2
|
|
(1,1) -> 0
|
|
(3,1) -> 2
|
|
Then the 1<sup>st</sup> smallest distance pair is (1,1), and its distance is 0.
