- The hash table array has capacity of 10. Capacity is the number of slots present in the array that is used to build the hashtable. The hash function returns the absolute value of the key mod the capacity of the hash table. a) Insert these keys in the hash table: 3,23,11,21,1,7,77,8 where the hash table uses quadratic probing to resolve collisions. b) Search and Delete 3 and 11 from the table. Be careful about changing the status of the table slot to “deleted” after deleting each item. c)Search 23 and 21 from the table and print their position.Hashing is the problem of finding an appropriate mapping of keys into addresses.a) Trueb) Falsewhich instructions best apply to the following prompt Implement an open addressing hash table to store a list of integers.

- 81. The process of finding some other position when hash address is occupied is classified as a. collision resolution b. address space resolution c. multiple hashing resolution d. chaining resolutionA A hash function works like an array index. Select one: a. False b. TrueWhy is it giving me an error and what do I have to change? PYTHON # Problem 2# Implement a hashtable using an array. Your implementation should include public methods for insertion, deletion, and# search, as well as helper methods for resizing. The hash table is resized when the max chain length becomes greater# than 3 during insertion of a new item. You will be using linear chaining technique for collision resolution. Assume# the key to be an integer and use the hash function h(k) = k mod m where m is the size of the hashtable. You can use# python list methods in your implementation of the chain or you can also use your linked list implementation from# coding assignment 2, problem 1.
