Merge overlapping intervals

CodingAlgorithms & data structuresMid–Senior~25 min

Given a list of intervals [start, end], merge all overlapping intervals and return the result sorted by start.

Implement
merge_intervals(intervals: list[list[int]]) → list[list[int]]
Examples
in[[[1,3],[2,6],[8,10],[15,18]]]out[[1,6],[8,10],[15,18]]
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.
