Concept explainers

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.

I NEED HELP IN THIS QUESTION OF DATA STRUCUTRE AND ALGO ASAP Consider the following scenario/assumptions: A hash table can store at most 11 elements. Indices are numbered from 0 to 10. It is currently empty (no elements yet). The hashing function is defined as H(k) = k % 11 The collision resolution technique is Linear Probing. Insert the following keys in the hash table in the sequence that they appear below: 172458 282459 392458 502461 612458 722463 832458 942465 1052458 1162467 Write on a piece of paper the contents of the resulting has table after inserting these keys. The table should contain 10 elements, with only one address that is left open, i.e., it is not occupied by any key
3. (A) Show the result when putting the keys 19,12,14,13,9 into a hash table of size 7, usingHashing with Linear Probing. The hash function is hash(k) = k mod 7. Don’t resize.(B) Continuing from part A, show the result after deleting 19.
