Hash Table

A hash table also called a hash map, is a data structure that maps key-value pairs. The hash table can be used in complex systems to provide fast access and compact storage. A hash table is a structure that stores data in an abstract data type kind of associative array. It keeps data in an array format, with a distinct index value for every data value. If the index of the required data is known, then the data can be accessed very easily.

(b) Using the quadratic probe sequence from part (a), write the pseudo-code for an algorithm called HashInsert(T, k) that takes as input a hash table T[0,..., 12] and a key k to be inserted into the table. Your algorithm must insert the item k into the table, using the probe sequence h(k, i) and return true if the insertion is successful, and false otherwise. *You do not have to check for duplicates (you can assume when inserting k that it is not already in the table). You can assume that the table was initially empty and only inserts were carried out, no deletions
