Solution: Remove Covered Intervals

Explore the method to remove covered intervals from a list by sorting intervals based on start points and endpoints. Learn to track the maximum endpoint seen to identify and count intervals not covered by others. Understand the approach and analyze its time and space complexity for efficient coding interview solutions.

We'll cover the following...
