Question
Given an R x C integer matrix (possibly rectangular, not necessarily square), return all of its elements in clockwise spiral order starting from the top-left corner. The matrix has at least one row and one column.
Implement
spiral_read(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.
Learn the concepts
Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.
Run or narrate your approach, then ask the coach.
