Interview Prompt

We're auditing a production log of integer event codes, and we need to know how often the same code recurs. Return the number of position pairs that hold the same code.

Summary

The same signals keep coming back. Count how often they meet.

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
