Interview Prompt

A circular buffer implementation needs a right-rotation operation. Rotate the list to the right by k positions: elements shifted off the end wrap around to the front.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your python solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
