write two functions: insertNode and forwardTraverse, for an XOR linked list, a.k.a, memory efficient doubly linked list (DLL) in C PL. Ordinary DLLs requires space for two addresses (one pointing to previous node and one to next node). However, XOR LLs use bitwise XOR operation to save space for one address. Consider the below ordinary DLL.

- Write a JAVA program that will maintain a phone directory using a Linked-List. The program should be able to perform the following operations: 1) Add persons details (first name, last name, phone number, city, address, sex and email) to the phone directory, where phone numbers in the directory have to be unique. (Note: each person record will store in one node in the linked-list and insert each person to the last) 2) Delete any person details by a given phone number. 3) Update telephone number by providing person first name. 4) Display all details of persons from a phone directory. 5) Search telephone number based on person first name. (Note: use sequential search to find all telephones for the given first name) 6) Sort all persons in the phone directory ascending based on person first name. (Note: use bubble or selection sort to arrange the entire phone directory) Project Outputs The output has to display a menu of choices. Then the user can select which operation want to perform.…Write a JAVA program that will maintain a phone directory using a Linked-List.

Resizing is the process of increasing a hash table's size when too many items have been added, 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, and insert 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.
- Given the following function to update a node in a standard linked list: public boolean update(Node head, int oldValue, int newValue) { if (head == null) return false; while (head != null) if (head.data == oldValue) { head.data = newValue; return true; } else head = head.next; return false; } There may be an error with the code. Answer the following: Design your own linked list of 4 nodes with different values If the code has an error, describe the issue and provide an example of calling the update function with values of your choice and show what the linked list looks like Also, show the code changes you would make to fix the error If the code does not have an error, provide an example of calling the update function with values of your choice and show what the linked list looks like For example, if your linked list was 1 -> 2 -> 3 ->…Consider a singly linked list where each node contains two fields – integerdata and node type pointer next.

- The program inserts a number of values into a priority queue and then removes them. The priority queue treats a larger unsigned integer as a higher priority than a smaller value. The priority queue object keeps a count of the basic operations performed during its lifetime to date, and that count is available via an accessor. In one or two places I have put statements such as op_count++;, but these are incomplete. We only count operations involved in inserting and removing elements, not auxiliary operations such as is_empty() or size() The class implements a priority queue with an unsorted vector. Your assignment is to re-implement the priority queue implementation using a heap built on a vector, exactly as we discussed in class. Leave the framework and public method interfaces completely unchanged. My original test program must work with your new class. You will have to write new private methods bubble_up and percolate_down in C++ language. You should not implement heapify or heapsort.…The program inserts a number of values into a priority queue and then removes them.

Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x and y coordinates. Your database should allow records to be inserted, deleted by name, and searched by name. Another operation that should be supported is to print all records within a given distance of a specified point/coordinate. The order of cities should be alphabetically by city name. Implement the database using: an array- based list implementation. By using JAVA.
