This video explains the Collision Handling using the method of Separate Chaining. Occasionally different strings are mapped to the same position in the array, which is called a hash collision. A hash function converts large keys into smaller keys that are used as indices in a hash table, allowing for fast lookup of objects in O(1) time. It is a combination of both Separate chaining and Open addressing. The following image shows a chaining-based hash table after 3 add operations. , < 1)? Consider average or max size of non-empty chains? For open addressing, half-full is a good rule of thumb New table size Twice-as-big is a good idea, except, uhm, that won’t be prime!

In case of a dynamic hash table, a treshold fill factor of 70% shall not be exceeded. Separate Chaining The elements are distributed in the hash table accoring to a modulo (%) operation between an element and the table size. This is resolved by imitating the Cuckoo bird: it pushes the other eggs or young out of the nest when it hatches Hashing is a technique used to uniquely identify objects by assigning each object a key, such as a student ID or book ID number. Each index in the array is called a bucket as it is a bucket of a linked list. There are different ways for dealing with this, above you see ‘separate chaining’: under every position of the array a linked list is maintained, which contains an unordered set of hash table entries.
