Sort table rows in Rust
Rust interview exercise on Practical, difficulty 2 of 3. Solve it in the editor beside a worked example, or cold in Interview mode with the example hidden; the tests run the moment you do.
Write sort_rows(rows, key, dir) that returns a sorted copy: by name or by score, ascending or descending. Enums for the key and the direction replace the stringly-typed arguments a JS version would take.
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Interview mode hides the example: solve it from memory, without the hint or the solution, and it counts as solved cold. Progress is saved in your browser, and in your account if you sign in.
