Note that this is only possible by using some sort of open addressing strategy. This explains why "closed hashing" and "open addressing" are synonyms.

Closed hashing and open hashing

WebAn alternative to hashing with buckets is closed hashing , also known (confusingly) as open addressing . Instead of storing a set at every array index, a single element is stored there. If an element is inserted in the hash table and collides with an element already stored at that index, a second possible possible location for it is computed. WebClosed Hashing. Hash Integer. Hash Strings. Linear Probing: f (i) = i. Quadratic Probing: f (i) = i * i. Double Hashing: f (i) = i * hash2 (elem)
