Implement a resize function for a hash table. Resizing is the process of increasing a hash table's size when too many items have beenadded, reducing the hash table's effectiveness.To resize the hash table, increase the size of the table by some small factor (not less than 2x), remove everything from the old table, andinsert it into the new larger table. Make sure to free up memory that is no longer used after resizing.Use the following heuristics to resize the table:• When the load factor exceeds .5.If no entry is found within the probe distance.Note, you may need to change insert as well to have a fully working solution.

Write a method called inversePrint. This method gets a head of a linkedlist and Recursively print from the last item to the first one. This is a Recursive method. If Recursive is not used you will get no mark for this question Do not reverse the linkedlist, only print it in reverse example call: in the main I will call your method like: buffer = myList.head; //This is a buffer to copy the head address inversePrint(buffer); After this, the order for myList should not changed. if myList has: 1->2->3->4->5 your function should print: 5-> 4 -> 3->2->1 but if I check myList the order should still be 1->2->3->4->5 you can assume the LinkedList code for all other operations exist and if you need you can use them Do Not create a new linkedlist in inverse Hint: use recursion does this for you really easy

In this task, two hash tables should should be implemented. You can follow the followinginstructions:- In class HashTable implement a hash table and consider the following:(i) Keys are integers (therefore also negative!) and should be stored in the tableint[] data.(ii) As a hash function take h(x) = (x · 701) mod 2000. The size of the table istherefore 2000. Be careful when computing the index of a negative key. Forexample, the index of the key x = −10 ish(−10) = (−7010) mod 2000 = (2000(−4) + 990) mod 2000 = 990.Hence, indices should be non-negative integers between 0 and 1999!(iii) Implement insert, which takes an integer and inserts it into a table. Themethod returns true, if the insertion is successful. If an element is already inthe table, the function insert should return false.(iv) Implement search, which takes an integer and finds it in the table. The methodreturns true, if the search is successful and false otherwise.(v) Implement delete, which takes an integer and deletes it…
Create a new concrete class that implements MyMap using open addressing with linear probing. For simplicity, use f(key) = key % size as the hash function, where size is the hash-table size. Initially, the hash-table size is 4. The table size is doubled whenever the load factor exceeds the threshold (0.5).

Use the hashing formula to calculate the hash of all the following strings. Use the Python Shell (the bottom area of Thonny) to help you calculate these numbers, since they get very large, very fast! A with a base of (11) and a hash size of (100): AB with a base of 11 and a hash size of 100: ABC with a base of 11 and a hash size of 100: ABC with a base of 33 and a hash size of 10000: Hello with a base of 31 and a hash size of 1000000000

Create a newconcrete class that implements MyMap using open addressing with quadratic probing.For simplicity, use f(key) = key % size as the hash function, where sizeis the hash-table size. Initially, the hash-table size is 6. The table size is doubledwhenever the load factor exceeds the threshold (0.5).
assume you have a HashMap class that uses a threshold of 0.75 (75%),regardless of the collision resolution mechanism used, and has an initial array size of 13. You may assume the array is resized when the current item to be added will make the load factor greater than or equal to the threshold. Recall that the load factor is the fraction of a hash map that is full. If the array is to be resized, assume the array doubles in size and adds one (2 * size + 1).Table 1 contains a list of items and their associated hash codes that were computed with somehypothetical hash function. Assume the items are added to a newly created instance of the HashMap class in the same order in which they are listed in the table. Based on this information, show what the array of the HashMap would look like after all the items have been added using both of the followinghash collision resolution techniques.1. Separate chaining2. linear probingProvide 2 arrays(one for each problem). One that uses separate…
