+<h2><a href="https://leetcode.com/problems/insert-interval/">57. Insert Interval</a></h2><h3>Medium</h3><hr><div><p>You are given an array of non-overlapping intervals <code>intervals</code> where <code>intervals[i] = [start<sub>i</sub>, end<sub>i</sub>]</code> represent the start and the end of the <code>i<sup>th</sup></code> interval and <code>intervals</code> is sorted in ascending order by <code>start<sub>i</sub></code>. You are also given an interval <code>newInterval = [start, end]</code> that represents the start and end of another interval.</p>
+
+<p>Insert <code>newInterval</code> into <code>intervals</code> such that <code>intervals</code> is still sorted in ascending order by <code>start<sub>i</sub></code> and <code>intervals</code> still does not have any overlapping intervals (merge overlapping intervals if necessary).</p>
+
+<p>Return <code>intervals</code><em> after the insertion</em>.</p>
+
+<p><strong>Note</strong> that you don't need to modify <code>intervals</code> in-place. You can make a new array and return it.</p>

+<p><strong class="example">Example 1:</strong></p>
+
+<pre><strong>Input:</strong> intervals = [[1,3],[6,9]], newInterval = [2,5]
+<strong>Output:</strong> [[1,5],[6,9]]
+</pre>
+
+<p><strong class="example">Example 2:</strong></p>
+
+<pre><strong>Input:</strong> intervals = [[1,2],[3,5],[6,7],[8,10],[12,16]], newInterval = [4,8]
+<strong>Output:</strong> [[1,2],[3,10],[12,16]]
+<strong>Explanation:</strong> Because the new interval [4,8] overlaps with [3,5],[6,7],[8,10].
