A hash table is a data structure that implements an associative array abstract data type, a structure that can map keys to values. It uses a hash function to compute an index into an array of buckets or slots, from which the desired value can be found. This provides a data structure that can be searched in O(1) time. Each bucket can consists of S slots. Each bucket can hold only one record if it contains one slot. Example: Lets consider a hash table with 26 buckets and 2 slots. Lets consider a hash function F(X) which maps all identifiers X based on the first character in X. The identifiers A,A2,D,GA,G are hashed into the corresponding buckets/slots as shown below. Here are the key components and characteristics of a hash table: Hash Function: A hash function takes a key as input and produces a hash code, which is used as an index to access the corresponding value in the hash table. The hash function should be deterministic (same key should always produce the same hash code) and prov...
