Solution: Merge Intervals

Statement

We are given an array of closed intervalsclosedintervals, intervals, where each interval has a start time and an end time. The input array is sorted with respect to the start times of each interval. For example, intervals = $[~[1,4], ~[3,6], ~[7,9]~]$ is sorted in terms of start times $1, ~3$, and $7$.

Your task is to merge the overlapping intervalsOverlapping intervals have at least one time (start/end) in common. and return a new output array consisting of only the non-overlapping intervals.

Constraints:

• $1 \leq$ intervals.length $\leq 10^3$
