Seems straightforward but the interesting part is figuring out how you're supposed to know who was added first.
Clarify the data model: admins have an 'added timestamp' or sequence number. The function should compare the two admins' addition times and return true if the first admin was added earlier than the second. If timestamps are equal, define a tie-breaker (e.g., lexicographic order of usernames) and document it.
Pro tip: Mention that in a real system, you'd likely store admin records in a map or database and query by username, so the function should handle missing admins gracefully (e.g., return false or throw an error). Also, discuss whether the rule is transitive and if it could be simplified to a comparison of sequence numbers.
Ask if the admin list is available, how 'added first' is determined (timestamp, insertion order, ID), and what to do if an admin doesn't exist or timestamps are equal.
Explain that you'll compare the two admins' addition times (or sequence numbers) and return true if the first admin's time is earlier than the second's.
Discuss what happens if either admin is not found, if timestamps are equal, or if the input is invalid. Propose a tie-breaker or error handling.
Sketch pseudocode or actual code: retrieve both admin records, compare their addition times, and return the boolean result.
Mention time and space complexity (e.g., O(1) if records are in a hash map, O(n) if scanning a list) and discuss alternative data structures for efficiency.
