Hashing: Hash Index

A hash indexA hash index is an index into the underlying array that supports a hash table. A hash index is determined by a hash function.... is an index into the underlying array that supports a hash tableA hash table (sometimes also called a hash map) is a data structure that is useful in situations when: you need very quick insertion and retrieval, you very rarely need to iterate over all your items, you don't care what order the items are stored (they don't need to be sorted, etc.), and the data you want to store has.... A hash index is determined by a hash functionA hash function exists within the context of hashing and hash tables. Data to be stored in hash tables includes a unique attribute (id number, username, etc.). Hash functions take the unique attribute and translate it into a hash index. Most algorithms take a numerical value as input, so if your unique attribute is text-based, translate your text into a....
