Understanding the Maximum Score of Non-overlapping Intervals Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given a 2D integer array intervals, where intervals[i] = [li, ri, weighti]. Interval i starts at position li and ends at ri, and has a weight of weighti. You can choose up to 4 non-overlapping intervals. The score of the chosen intervals is defined as the total sum of their weights. Return the lexicographically smallest array of at most 4 indices from intervals with maximum score, representing your choice of non-overlapping intervals. Two intervals are said to be non-overlapping if they do not share any points. In particular, intervals sharing a left or right boundary are considered overlapping.
