This reported Affirm coding interview problem requires you to process a continuous stream of time-bounded promotional offers and user redemption events parsed from standard input. You must validate offer validity windows against event timestamps while strictly enforcing per-user redemption limits to track state accurately. The task evaluates your ability to design clean event-driven data processing pipelines and manage temporal state constraints effectively. Access to the full problem requirements, sample event streams, and verified model solution requires an active subscription.

This algorithm design challenge, frequently encountered in interviews at Affirm, requires you to build a custom dictionary data structure that supports efficient insertion, deletion, lookup, and weighted random value retrieval. You must ensure that extracting a random value respects the frequency distribution of stored elements rather than treating every unique entry with equal probability. The task tests your mastery of combining hash maps and linear data structures to achieve optimal time complexities for all required methods.
