Non-overlapping Intervals

Understand how to solve the non-overlapping intervals problem by identifying and removing the minimum number of overlapping intervals. This lesson helps you master an efficient algorithm running in O(n log n) time and constant space, a common pattern in coding interviews.

Statement

Given an array of intervals where intervals[i] contains the half-open intervalAn interval that contains only one of its boundary elements. The “(” parenthesis denotes the exclusion of the starting point. The “]” bracket denotes the inclusion of the ending point., (starti,endi](start_{i}​, end_{i}], your task is to find the minimum number of intervals you need to remove to make the rest of the intervals non-overlapping.

Note: Two intervals (a,b](a, b] and (c,d] ...
