Rotate right by k in TypeScript
TypeScript interview exercise on Arrays, difficulty 2 of 3. Solve it in the editor beside a worked example; the tests run the moment you do.
Write rotate(arr, k) that returns a new array rotated to the right by k positions. k may exceed the length.
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.
