Rotate right by k, in place in Rust
Rust interview exercise on Vectors & Slices, difficulty 2 of 3. Solve it in the editor beside a worked example; the tests run the moment you do.
Write rotate_right(items, k) that rotates the Vec k places to the right in place: no new Vec, nothing returned. k may be larger than the length, and the Vec may be empty.
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Progress is saved in your browser, and in your account if you sign in.
