Interview Prompt

You're compacting a run of sensor readings where each value repeats on the wire until it changes. Collapse every stretch of identical consecutive readings down to just the first reading of the stretch, and return the compacted result.

Summary

It has a problem with repetition.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write and run your Python against test cases
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
