Which of the following data structure works on the "LIFO" principle? A Stacks. B Queues. Deque. D Hash tables.

Implement a part of functionality for the Netflix DVD queue. It's a service that allows a user to create a list of desired movies and then sends DVDs with movies on top of this list to the subscriber one at a a time. A subscriber should be able to create a list of desired movies and manipulate the order in a movie queue in their account. Your program will implement some of the desired functionality by storing the list of movie titles in a linked list. You are provided with the following files available in "Downloadable files" section: • MovieList.h contains a class declaration for the class that represents a list of movies. • Driver.cpp contains a main function you can use to test your implementation. You will be responsible for providing the MovieList.cpp file, including the implementation of the MovieList member functions (described below): MovieList and ~MovieList: creates an empty list, and deallocates all the nodes in the list, respectively. display(ostream& out) Print movie…

34, question is in Java, thanks

Please give a detailed answer to all of the questions below.

Description: In this project, you are required to make a java code to build a blockchain including multiple blocks. In each block, it contains a list of transactions, previous hash - the digital signature of the previous block, and the hash of the current block which is based on the list of transactions and the previous hash. If anyone would change anything with the previous block, the digital signature of the current block will change. When this changes, the digital signature of the next block will change. Detailed Requirements: 1. Define your block class which contains three private members and four public methods. a. Members: previousHash (int), transactions (String[]), and blockHash (int); b. Methods: i. Block( int previousHash, String[] transactions){} ii. getPreviousHash(){} iii. getTransaction(){} iv. getBlockHash(){} 2. Using ArrayList to design your Blockchain. 3. Your blockchain must contain genesis block and make it to be the first block. 4. You can add a block to the end of…

Consider the following linked list and pointer called temp: head 3 6 2 10 エローミー H temp + We then perform the following operations: 1. Create a variable called x, and assign it the value obtained from dereferencing temp 2. Update temp to point at next node 3. Multiply x by 4 What is the final value of x? null

Without using the built in java hash table Write a Java program to get input from the keyboard to enter an integer.Write a hash function to hash the integer.Store the integer in a DataItem object.Create a hash table to store the DataItem in the hash table at the hashed location.Write a function to search a hash function for an integer value and display it from the DataItemobject at the hashed location

Suppose a program builds and manipulates a linked list: What two special nodes would the program typically keep track of? Describe two common uses for the null reference in the node of the linked lists.
