Interview Prompt
A reviewer auditing a number-theory quiz bank flags an integer as perfect when it equals the sum of all its positive divisors smaller than itself. Given a positive integer `n`, report whether it qualifies.
Summary
Some numbers have a rare quality that mathematicians revere.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your Python against test cases
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
