WebMar 10, 2024 · The secondary hash table isn't even designed to handle collisions (e.g. chaining or open addressing). It's just a hash table. And even if it did somehow, a p<1/2 doesn't necessarily mean that you get collision-free lookups (even on avg) since it would depend on how you handle those collisions. $\endgroup$ WebApr 27, 2024 · Table of Contents.
