In this problem, we are given an array of intervals, where each interval is an object with a start and end property. The intervals are not necessarily sorted. Our task is to merge any overlapping intervals and return the resulting array of intervals.
This solution has a time complexity of O(n * log(n)), since the intervals are sorted using the built-in Array.sort() function, which has a time complexity of O(n * log(n)). The space complexity is O(n), since we create a new array to store the merged intervals.
I hope this helps! Let me know if you have any questions or suggestions for improvement.
