Statement

We are given an array of closed intervalsclosedintervals called intervals, where each interval has a start time and an end time and is represented as intervals[i] = [start_i, end_i]. Your task is to merge the overlapping intervalsOverlapping intervals are two or more intervals with at least one common point in time. and return a new output array consisting of only the non-overlapping intervals.

Constraints:

$1 \leq$ intervals.length $\leq10^3$
intervals[i].length $== 2$ ...
