Hash table is one of the most important data structures that uses a special function known as a hash function that maps a given value with a key to access the elements faster. A Hash table is a data structure that stores some information, and the information has basically two main components, i.e., key and value.

WebWhen we insert a value into the hash table, we calculate its hash, modulo by 16, and use that as the array index. So with an array of size 16, we’d insert bar at index 10, bazz at 8, bob at 4, and so on. Let’s insert all the items into our hash table array (except for x – we’ll get to that below): Index. 0.
