Solution: Remove Covered Intervals

Explore how to remove intervals covered by others from a list by utilizing sorting and iteration techniques. This lesson teaches you to sort intervals with a custom comparator, track endpoints to identify coverage, and calculate the count of remaining intervals. You will understand the time complexity of O(n log n) and the space complexity involved in sorting, applying this approach to coding interview problems involving intervals.

Statement

Given an array of intervals, where each interval is represented as intervals[i] =[li,ri)= [l_i, r_i) (indicating the range from lil_i to rir_i, inclusive of lil_i ...
