Solution: Merge Intervals

Explore how to efficiently merge overlapping intervals by sorting and iterating through a list of intervals. Learn to detect overlaps and update intervals to form a non-overlapping set. This lesson helps you understand the problem, implement an optimized O(n log n) solution, and prepare for interval pattern challenges in coding interviews.

We'll cover the following...

Statement
Solution
- Naive approach
- Optimized approach using the intervals pattern

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 $== 2$ ...
