keys to values.
A hash table is an
data structure for storing and retrieving data.
Hash works by transforming the key using a
into a hash, which is then used to index an array
Hash tables can be
using a variety of data structures, including arrays, linked lists, and binary trees.
of hash tables is that they can suffer from collisions, which occur when two different keys are mapped to the same hash
There are various strategies for
, including separate chaining and open addressing.
Hash functions transform keys into hashes using a
operation and the size of the array.
