Overview
In open addressing, keys always reside in the hash table. Collisions are dealt with by searching for other empty buckets within the hash table.
%%ANKI Basic What does "closed" refer to in term "closed hashing"? Back: A key must reside in the hash table. Reference: “Hash Tables: Open vs Closed Addressing | Programming.Guide,” accessed June 12, 2024, https://programming.guide/hash-tables-open-vs-closed-addressing.html.
END%%
%%ANKI Basic What does "open" refer to in term "open addressing"? Back: A key is not necessarily stored in the slot it hashes to. Reference: “Hash Tables: Open vs Closed Addressing | Programming.Guide,” accessed June 12, 2024, https://programming.guide/hash-tables-open-vs-closed-addressing.html.

%%ANKI Basic Why is the theoretical maximum load factor of open addressing unbounded? Back: An open addressing hash table can only store as many entries as slots.

When is the load factor of an open addressing hash table 0?
Back: When no entries are stored in the table.
