Example 1:
Input: intervals = [[1,3],[1,5],[6,7]]
Output: [[1,5],[6,7]]
Example 2:
Input: intervals = [[1,2],[2,3]]
Output: [[1,3]]
Example 1:
Input: intervals = [[1,3],[1,5],[6,7]]
Output: [[1,5],[6,7]]
Example 2:
Input: intervals = [[1,2],[2,3]]
Output: [[1,3]]
Given an array of intervals where intervals[i] = [start_i, end_i], merge all overlapping intervals, and return an array of the non-overlapping intervals that cover all the intervals in the input.
You may return the answer in any order.
Note: Intervals are non-overlapping if they have no common point. For example, [1, 2] and [3, 4] are non-overlapping, but [1, 2] and [2, 3] are overlapping.
1 <= intervals.length <= 1000intervals[i].length == 20 <= start <= end <= 1000
