tab: English
 
<p>Given an array&nbsp;of <code>intervals</code>&nbsp;where <code>intervals[i] = [start<sub>i</sub>, end<sub>i</sub>]</code>, merge all overlapping intervals, and return <em>an array of the non-overlapping intervals that cover all the intervals in the input</em>.</p>
 
<p>&nbsp;</p>
<p><strong class="example">Example 1:</strong></p>
 
<pre>
<strong>Input:</strong> intervals = [[1,3],[2,6],[8,10],[15,18]]
<strong>Output:</strong> [[1,6],[8,10],[15,18]]
<strong>Explanation:</strong> Since intervals [1,3] and [2,6] overlap, merge them into [1,6].
</pre>
 
<p><strong class="example">Example 2:</strong></p>
 
<pre>
<strong>Input:</strong> intervals = [[1,4],[4,5]]
<strong>Output:</strong> [[1,5]]
<strong>Explanation:</strong> Intervals [1,4] and [4,5] are considered overlapping.
</pre>
 
<p><strong class="example">Example 3:</strong></p>
 
<pre>
<strong>Input:</strong> intervals = [[4,7],[1,4]]
<strong>Output:</strong> [[1,7]]
<strong>Explanation:</strong> Intervals [1,4] and [4,7] are considered overlapping.
</pre>
 
<p>&nbsp;</p>
<p><strong>Constraints:</strong></p>
 
<ul>
	<li><code>1 &lt;= intervals.length &lt;= 10<sup>4</sup></code></li>
	<li><code>intervals[i].length == 2</code></li>
	<li><code>0 &lt;= start<sub>i</sub> &lt;= end<sub>i</sub> &lt;= 10<sup>4</sup></code></li>
</ul>

<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&nbsp;<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>&nbsp;。</p>
 
<p>&nbsp;</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].
</pre>
 
<p><strong>示例&nbsp;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>
 
<p><strong class="example">示例 3:</strong></p>
 
<pre>
<b>输入:</b>intervals = [[4,7],[1,4]]
<b>输出:</b>[[1,7]]
<b>解释:</b>区间 [1,4] 和 [4,7] 可被视为重叠区间。
</pre>
 
<p>&nbsp;</p>
 
<p><strong>提示:</strong></p>
 
<ul>
	<li><code>1 &lt;= intervals.length &lt;= 10<sup>4</sup></code></li>
	<li><code>intervals[i].length == 2</code></li>
	<li><code>0 &lt;= start<sub>i</sub> &lt;= end<sub>i</sub> &lt;= 10<sup>4</sup></code></li>
</ul>
