Question
Parse a single CSV line into fields, respecting RFC 4180 quoting. Fields are comma-separated. A field may be wrapped in double quotes, inside which commas are literal and a doubled quote ("") represents a single literal quote character. Return the list of field strings (quotes removed, escapes resolved). An empty input string yields a list containing one empty string.
parse_csv_line(line: str) → list[str]["\"hello, world\",x"]out["hello, world","x"]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.
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.
