Chunk into groups in Rust
Rust interview exercise on Vectors & Slices, 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 chunk(items, size) that splits items into consecutive groups of size; the last group may be shorter. A size of 0 returns an empty Vec (the slice method panics on 0).
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.
