Merge Intervals - LeetCode 56 - Coding Interview Questions

----- ------

The problem of merging overlapping intervals is a common one that frequently appears in coding interviews.
In this problem, you are given an array of intervals, where each interval is represented as a list with a start and end value and Your task is to merge all overlapping intervals and return an array of non-overlapping intervals that cover all the intervals in the input.

In this video, we'll go over a simple and efficient solution to this coding challenge.
The solution involves sorting the intervals by their start values, then iterating through the sorted array and adding each interval to a result array if it does not overlap with any of the intervals already in the result array. If an interval does overlap with an interval in the result array, the end value of the interval in the result array is updated to the maximum of the two end values.

Practice this problem to improve your coding skills and increase your chances of success in your next coding interview.

Is the time complexity of this n2 or nlogn. Since as you continue looping you don't have to check the previous values, only the ones in front of it after sorting.
