Interview Prompt

We're snapping a batch of sensor readings onto a fixed set of reference points. Given `keys` and `values` as lists of integers, return a dict that pairs each key with the reference value nearest to it by absolute distance.

Summary

Close enough counts. Ties go low.

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
