Answer
A poor hash function causes more collisions, degrading performance to O(n).
If a hash function distributes elements unevenly, many elements end up in the same bucket, turning HashSet's operations into linear time complexity. In a catalog, using poor hash logic for product IDs could lead to slow operations.
