Non-overlapping intervals

CodingAlgorithms & data structuresMid–Senior~25 min

Given a set of intervals, return the minimum number you must remove so that the rest are non-overlapping.

Implement
erase_overlap_intervals(intervals: list[list[int]]) → int
Examples
in[[[1,2],[2,3],[3,4],[1,3]]]out1
What a strong answer looks like

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
