Spiral matrix

CodingAlgorithms & data structuresMid–Senior~25 min

Given an m x n matrix, return all its elements in spiral order (clockwise from the top-left).

Implement
spiral_order(matrix: list[list[int]]) → list[int]
Examples
in[[[1,2,3],[4,5,6],[7,8,9]]]out[1,2,3,6,9,8,7,4,5]
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.
