You are given an array of non-overlapping intervals intervals where intervals[i] = [starti, endi] represent the start and the end of the ith interval and intervals is sorted in ascending order by starti. You are also given an interval newInterval = [start, end] that represents the start and end of another interval.
Insert newInterval into intervals such that intervals is still sorted in ascending order by starti and intervals still does not have any overlapping intervals (merge overlapping intervals if necessary).
Return intervals after the insertion.
\n
Example 1:
\n\n\nInput: intervals = [[1,3],[6,9]], newInterval = [2,5]\nOutput: [[1,5],[6,9]]\n\n\n
Example 2:
\n\n\nInput: intervals = [[1,2],[3,5],[6,7],[8,10],[12,16]], newInterval = [4,8]\nOutput: [[1,2],[3,10],[12,16]]\nExplanation: Because the new interval [4,8] overlaps with [3,5],[6,7],[8,10].\n\n\n
\n
Constraints:
\n\n0 <= intervals.length <= 104intervals[i].length == 20 <= starti <= endi <= 105intervals is sorted by starti in ascending order.newInterval.length == 20 <= start <= end <= 105给你一个 无重叠的 ，按照区间起始端点排序的区间列表。
\n\n在列表中插入一个新的区间，你需要确保列表中的区间仍然有序且不重叠（如果有必要的话，可以合并区间）。
\n\n\n\n
示例 1：
\n\n\n输入：intervals = [[1,3],[6,9]], newInterval = [2,5]\n输出：[[1,5],[6,9]]\n\n\n
示例 2：
\n\n\n输入：intervals = [[1,2],[3,5],[6,7],[8,10],[12,16]], newInterval = [4,8]\n输出：[[1,2],[3,10],[12,16]]\n解释：这是因为新的区间\n\n[4,8]与[3,5],[6,7],[8,10]重叠。
示例 3：
\n\n\n输入：intervals = [], newInterval = [5,7]\n输出：[[5,7]]\n\n\n
示例 4：
\n\n\n输入：intervals = [[1,5]], newInterval = [2,3]\n输出：[[1,5]]\n\n\n
示例 5：
\n\n\n输入：intervals = [[1,5]], newInterval = [2,7]\n输出：[[1,7]]\n\n\n
