My homework was to design and implement a simple social network program in Java. 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…
Please help me with the assignment below The assignment: Make a telephone lookup program. Read a data set of 1,000 names and telephone numbers from a file that contains the numbers in random order. Handle lookups by name and also reverse lookups by phone number. Use a binary search for both lookups. This assignment needs a resource class and a driver class. The resource class and the driver class will be in two separate files. The driver class needs to have only 5 or 7 lines of code. The code needs to be written in Java. Please help me with exactly what I asked for help.
Develop a program that implements any of the indexing types. Use methods to organize your code and do not forget to follow naming conventions.
In C programming Write a function printCourseRow() which receives a course pointer and prints all its fields as a single row. Use proper formatting so that when we print 2 or more courses as rows, the same members align below each other. Test the function, but don’t include the testing code in your homework.Upload a screenshot of a sample output.

Implement the function merge_dict. The merge_dict function merges two dictionaries with the same keys together by adding up their values for the corresponding keys and returning the resulting dictionary. def merge_dict(d1, d2): """Returns a dictionary that is the result of two dictionaries being merged together. Dictionaries are merged by adding up their values. You can assume that the same keys appear in both dictionaries. >>> data8 = {"midterms":1, "projects":3} >>>data100 = {"midterms":2, "projects":3} >>> combined_exams = merge_dict (data8, data100) >>> combined_exams {'midterms': 3, 'projects': 6} >>> sunday_orders = {"pizza": 3, "hot dogs": 2, "fries": 5} >>> monday_orders = {"pizza": 1, "hot dogs": 1, "fries": 8} >>> combined_orders = merge_dict (sunday_orders, monday_orders) >>> combined_orders {'pizza': 4, 'hot dogs': 3, 'fries': 13} "*** YOUR CODE HERE ***'
In this project, you will implement a single linked list structure that represents a list of Tawjihi records and do different operations on the records within that linked list. The inputs for the project will be the two Tawjihi files (One file for West Bank and the other for Gaza records). Each line in those files contains the Tawjihi record of a student (seat number, average, and branch). You may use the code you wrote/implemented during the lectrure to create and store Tawjihi record data into your single Linked List(s). You are free to use as many linked lists as needed. YOU MAY NOT USE ARRAYS IN THIS PROJECT. For good user experience, you will need to implement a user interface. In the user interface there should be a way to select between WestBank or Gaza as well as an option to select between branchs "Literary or Science". According to the previouse selction the following functions will operate in the specfic selected data above: 1. An option to insert new Tawjihi record into the…
What is the difference between void and NULL pointers? Give specific instances to back up your response. Give the differences in TABULAR form.
This project is divided into two parts. Part 1. You will be implementing a dictionary structure (storing pairs key/value), and reading the user input to manipulate the structure. The commands implemented in that stage are put, get, and del. It will be important not to leak any memory in these functions. Part 2. You will add two more commands: clr, which clears the dictionary, and siz, which prints the size of the dictionary. Again, clr will have to make sure not to leak any memory. You will also implement a destructor for your dictionary object. The dict.c file that the problems need to be solved is in the image given
Focus on dictionary methods, use of functions, and good programming styleFor this assignment, you will create a glossary (dictionary) of technical terms and definitions. It will be set up as a Python dictionary structure. The file glossary_starter.py is a complete starter framework for the assignment. It includes some initial values for the dictionary. It is long because most of the code has already been written for you.Your task is to complete the five individual functions for adding and deleting terms, looking up terms, listing them, and printing out both the terms and definitions. These functions are all short, just a couple of lines, and use basic dictionary methods and techniques. Here is some sample output. Glossary system 1) Add a term 2) List terms 3) Get a definition 4) Delete a term 5) Print out dictionary 6) Quit Enter your choice: 2 argument dictionary hashmap list set 5 terms Glossary system 1) Add a term 2) List terms 3) Get a definition 4) Delete a term 5) Print…
