<p>给定一个整数数组,返回所有数对之间的第 k 个最小<strong>距离</strong>。一对 (A, B) 的距离被定义为 A 和 B 之间的绝对差值。</p>
<p><strong>示例 1:</strong></p>
<pre>
<strong>输入:</strong>
nums = [1,3,1]
k = 1
<strong>输出0</strong>
<strong>解释:</strong>
所有数对如下:
(1,3) -&gt; 2
(1,1) -&gt; 0
(3,1) -&gt; 2
因此第 1 个最小距离的数对是 (1,1),它们之间的距离为 0。
</pre>
<p><strong>提示:</strong></p>
<ol>
<li><code>2 &lt;= len(nums) &lt;= 10000</code>.</li>
<li><code>0 &lt;= nums[i] &lt; 1000000</code>.</li>
<li><code>1 &lt;= k &lt;= len(nums) * (len(nums) - 1) / 2</code>.</li>
</ol>
