A hash table is an efficient data structure to store and access data via keys. In this problem, you need to find the longest subarray of distinct elements. For example, given an array A = <milk, water, 6724, water, soda, beer, apple, grape, wine>, the longest subarray is <milk, water, 6724, soda, beer, apple, grape, wine> Hint: you need to keep track and update the positions of the elements. a) Explain how many unique subarrays are there from a given array b) Describe your ideas on how to solve the problem, especially how hash tables can be used to keep track of the important information c) Write the most efficient algorithm (pseudo code) to solve this problem with complexity analysis. You can assume that a good hash function is given.
Why 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. You can make necessary changes to __hashtable initialization in the __init__ method# if you are using your linked list implementation. The provided code uses python lists for the __hashtable variable. class HashTableChain: def __init__(self, size=10): # Initialize the hashtable with the given…
