- Write a c++ program that reads in input commands related to a queue with no more than ten elements and performs the specified operations. Note that you should create three files, one for the main, one for Queue.h, and one for Queue.cpp. Those commands are: 'E', which will be followed by a number. You should enqueue that number 'D', which will dequeue the value from the front of the queue and print it, followed by a new line 'K'. which will peek at the value at the front of the queue and print it, followed by a new line 'Q', which will quit the program You can assume that all the input is valid.You will write a C++ program to process the lines in a text file using a linked list ADT and raw pointers. Node class You will create a class “Node” with the following private data attributes: line – line from a file (string) next - (pointer to a Node) Put your class definition in a header file and the implementation of the methods in a .cpp file.Follow the style they use in the book of having a "#include" for the implementation file at the bottom of the header file. You will have the following public methods: Accessors and mutators for each attribute Constructor that initializes the attributes to nulls (empty string and nullptr) LinkedList class You will create a class “LinkedList” with the following private data attributes: headPtr – raw pointer to the head of the list numItems – number of items in the list Put your class definition in a header file and the implementation of the methods in a .cpp file.Follow the style they use in the book of having a "#include" for the…The question should be done in C++, please give explanation and running result. 1.

I should use an adjacency matrix data structure in my implementation. Write a social network program in Java. The default information for this network is stored in two files: index.txt and friend.txt. The file index.txt stores the names of the people in the network – you may assume that we only store the given names and these names are unique; and friend.txt stores who knows whom. The program must read these two files. The following section describes the format of these two files. The friend.txt takes the following format. The first line is the number of pairs of friends. Each subsequent line has two integer numbers. The first two numbers are the indices of the names. The following is an example of friend.txt:50 31 30 12 41 5 The index.txt stores the names of the people in the network. The first line is the number of people in the file; for example:60 Gromit1 Gwendolyn2 Le-Spiderman3 Wallace4 Batman5…You are to use the started code provided with QUEUE Container Adapter methods and provide the implementation of a requested functionality outlined below.

- Write a Java program that interacts with a user to process information retrieval queries. Your program should prompt the user for a data directory, then a query, then display the documents that contain the query term. The documents should be ranked in order of their TF-IDF score. There are several tasks that must be completed to complete this assignment. First, prompt for the directory containing the collection of data as with the earlier assignments. Then, you will need to build an inverted index or incidence matrix. Each entry in the inverted index should consist of a vocabulary word, the word’s document frequency, and the word’s postings. Each posting should contain a document ID and the term frequency of the word with respect to the document. Alternatively, you may build a (non-boolean) incidence matrix. This would contain a table where each row corresponds to a vocabulary word, and each column corresponds to a document. Each cell in the table contains the term frequency (which is…In this project you are to design a process queue that is responsible for handling the process requests coming from different users. You have to take into consideration that users have different levels of privileges and priorities. Each user has an identification number and a password, in addition to process priorities. One good idea is to design the queue using an array or pointers while preserving the first-in first-out concept of the queue. For every process request received, the program should check the privileges of that request and whether it can be moved forward in the queue to be served by the operating system prior to serving the other requests. Using the programming language of your choice (preferably C+), write the process queue that would handle the user request. The program must allow for requests coming from different users or from one user.sing good OOP, write a C++ program that will read an input file to manage a list of students waiting to register for a ourse using a linked list. The input file name is WaitList.txt and is located in the current directory of the project. The file layout is as follows: action student name Actions are defined as follows: 1 - add student name to the end of the linked list2 - add student name to the beginning of the linked list3 - delete the student at the beginning of the linked list4 - delete the student at the end of the linked list Actions #1 and #2 require student names. Actions #3 and #4 do not. For example, if the input file contents contained: 1 Sally Sue Student1 Peter Pupil1 Sam Scholar42 Terri Tutor1 Abby Achiever32 Bill Brain The program would display the wait list as follows: The Wait List: 1. Bill Brain2. Sally Sue Student3. Peter Pupil4. Abby Achiever End of List. Then the program will prompt the user if they wish to delete a student by name. If…
- Implement in C Programming 9.9.1: LAB: Thesaurus Given a set of text files containing synonyms for different words, complete the main program to output the synonyms for a specific word. Each text file contains synonyms for the word specified in the file’s name, and the synonyms within the file are grouped according to the synonyms' first letters, separated by an '*'. The program reads a word and a letter from the user and opens the text file associated with the input word. The program then stores the contents of the text file into a two-dimensional array of char* predefined in the program. Finally the program searches the array and outputs all the synonyms that begin with the input letter, one synonym per line, or a message if no synonyms that begin with the input letter are found. Hints: Use the malloc() function to allocate memory for each of the synonyms stored in the array. A string always ends with a null character ('\0'). Use ASCII values to map the row index of the array to the…Write code in C language. Create an integer array as input in C programming language. Create two threads. The first thread sums the even elements of the array, and the second thread sums the odd elements of the array. You can declare only one function outside the main functionPart Two: Implementing a rainbow table You are to write a program, in C/C++, Java or Python, that should run using the following instruction: $ ./Rainbow Passwords.txt where the file Passwords.txt contains a list of possible passwords. The password file contains a password per line, as in the provided words file and consists of strings of printable characters. Any password used must be taken from this file, so the only stored hash information needs to relate to those entries in the file. The program is used to find pre-images for given hash values. Rainbow tables can be used to solve pre-image problems for hash functions. At the simplest level they can simply be a list of hash values and the corresponding pre-images, often from some dictionary. This can be expensive in terms of storage space however, and a more efficient way of identifying pre-images involves the use of the hash function and reduction functions. First step The process is as follows: 1. Read in the list of possible…
