<p>以数组 <code>intervals</code> 表示若干个区间的集合，其中单个区间为 <code>intervals[i] = [start<sub>i</sub>, end<sub>i</sub>]</code> 。请你合并所有重叠的区间，并返回 <em>一个不重叠的区间数组，该数组需恰好覆盖输入中的所有区间</em> 。</p>

<p><strong>示例 1：</strong></p>
|
|||
|
|
|
|||
|
|
<pre>
|
|||
|
|
<strong>输入：</strong>intervals = [[1,3],[2,6],[8,10],[15,18]]
|
|||
|
|
<strong>输出：</strong>[[1,6],[8,10],[15,18]]
|
|||
|
|
<strong>解释：</strong>区间 [1,3] 和 [2,6] 重叠, 将它们合并为 [1,6].

<p><strong>示例 2：</strong></p>
|
|||
|
|
|
|||
|
|
<pre>
|
|||
|
|
<strong>输入：</strong>intervals = [[1,4],[4,5]]
|
|||
|
|
<strong>输出：</strong>[[1,5]]
|
|||
|
|
<strong>解释：</strong>区间 [1,4] 和 [4,5] 可被视为重叠区间。</pre>
