To implement this feature, we need to first sort the meetings based on startTime. Then, we will process the meetings that come before the new meeting, insert the new meeting, and merge the new meeting with the older ones if needed.

Here is how we will implement this feature:

First, we need to sort the meetings according to the starting times.

After the meetings are sorted, we will create a new list called output and add the meetings that start before the newMeeting to it.

Then, we will add the newMeeting to the output and merge it with the previously added meeting (if the new meeting starts before the previously added meeting).

Finally, we will add the remaining meetings to the output and merge it with the last added meeting (if the last added meeting starts before the previously added meeting).
