- An “inverted file” is a critical data structure for implementing applications like the index of a book, or a web search engine. Given a document D (which can be viewed as an unordered, numbered list of words), an inverted file is an ordered list of words L such that for each word W in L, we store the indices of the places in D where W appears. Write a C# program (from scratch please, written by yourself (ask instructor if you are stuck), not borrowed from any other sources) that reads in a list of words separated by spaces from a text file, then uses an efficient O(N) algorithm to create the inverted file index (hint: consider the topic of this chapter, consider using a Dictionary/hashtable to help you), and writes this index out to another file or prints it to the screen. Each line of the output file should start with the next word (the words should be listed in alphabetical order, and this sorting does not have to be part of the O(N) runtime complexity, e.g. you can use regular…Write a program in c++ and make sure it works, that reads a list of students (first names only) from a file. It is possible for the names to be in unsorted order in the file but they have to be placed in sorted order within the linked list.The program should use a doubly linked list.Each node in the doubly linked list should have the student’s name, a pointer to the next student, and a pointer to the previous student. Here is a sample visual. The head points to the beginning of the list. The tail points to the end of the list. When inserting consider all the following conditions:if(!head){ //no other nodes}else if (strcmp(data, head->name)<0){ //smaller than head}else if (strcmp(data, tail->name)>0){ //larger than tail}else{ //somewhere in the middle} When deleting a student consider all the following conditions:student may be at the head, the tail or in the middleBelow, you will find a sample of what the file looks like. Notice the names are in…You will write a C++ program to process the lines in a text file using a linked list ADT and raw pointers.

- Write a program in C++ that prints a sorted phone list from a database of names and phone numbers. The data is contained in two files named "phoneNames.txt" and "phoneNums.txt". The files may contain up to 2000 names and phone numbers. The files have one name or one phone number per line. To save paper, only print the first 50 lines of the output. Note: The first phone number in the phone number file corresponds to the first name in the name file. The second phone number in the phone number file corresponds to the second name in the name file. etc. You will find the test files in the Asn Five.zipYou will write a program to process the lines in a text file using a linked list ADT and raw pointers.

Sequence.txt file contains a sequence of relative letter positions. The initial position is at the beginning of the list which is ‘A’. The first number in the sequence is ‘3’. So the current position will move forward for three steps. Then the first letter to output is ‘D’ and now the current position is at ‘D’ as well. The second number in the sequence is ‘-3’.

- 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.

- How can I make a binary search tree of a java program that can, in theory, store objects of any class (use templates)? It will use it to store a simple data structure, a WordIndex structure, which consists of two data elements: a String and any means you wish to store a list of integers. It will then use these structures in a program that will read a text file, counting every word in the file and tracking on which line(s) each word appears, not entering duplicate values. (Hint: use readLine() to read the file one line at a time.)Write a program that maintains a personal phone book in C. The program allows to:▪ Add and Delete entries from the phone book,▪ Search the phone book for a specific entry by last name or by phone number, and▪ Print out the entire entries in the phone book.The data in the phone book is maintained by storing in memory with the use of a singly linked list, withone list node per entry. Each node contains members for storing a person’s family name, first name, address,and the phone number. Use strings to store this information. The linked list must be kept in increasingalphabetical order, sorted by family name. There are no duplicate entries with the same family nameallowed in the phone book.
