Write an application to test the HuffmanTree class for java.
a. The application will need to read a text and build a frequency table for the characters occurring in that file.
b. Once that table is built, create a Huffman code tree and then a string consisting of '0' and '1' digit characters that represents the code string for that file.
c. Then read that string back in and re‐create the contents of the original file and output it.

- In this programming exercise you will implement two functions. The first function will prompt the user for a file containing the number of vertices and entries of the adjacency matrix of a graph. It will return a two-dimensional list (a list of lists) containing the adjacency matrix. The textfile is named inputfilename.txt am trying to read for the matrix 80 1 2 3 100 100 100 1001 0 2 100 3 4 100 1002 2 0 4 4 100 5 1003 100 4 0 100 100 4 100100 3 4 100 0 3 3 3100 4 100 100 3 0 100 1100 100 5 4 3 100 0 2100 100 100 100 3 1 2 0 def readMatrix(inputfilename): ''' Returns a two-dimentional array created from the data in the given file.

Word pairs consist of a name and a phone number (both strings), separated by a comma. That list is followed by a name, and your program should output the phone number associated with that name. Output "None" if name is not found. Ex: If the input is: 3 Joe,123-5432 Linda,983-4123 Frank,867-5309 Frank the output is: 867-5309 Your program must define and call the following function. The return value of GetPhoneNumber is the phone number associated with the specific contact name.string GetPhoneNumber(vector<string> nameVec, vector<string> phoneNumberVec, string contactName) Hint: Use two vectors: One for the string names, and the other for the string phone numbers.Question-2: Write a Python program that takes a string as an input where multiple numbers are separated by hashes(#). Your first task is to create a list of numbers and print it. Your second task is to create a dictionary that will have the index of the list as key, and for the even indices, multiplication from start to that index as value, while for the odd indices, summation from start to that index as value. Finally, print the dictionary. . ================================================ Sample Input 1: 1#2#3#4 Sample Output 1: [1, 2, 3, 4] {0: 1, 1: 3, 2: 6, 3: 10} Explanation 1: key 0 → value 1 key 1 → value 1+2 = 3 key 2 → value 1x2x3 = 6 key 3 → value 1+2+3+4 = 10 ================================================ Sample Input 2: 5#6#7 Sample Output 2: [5, 6, 7] {0: 5, 1: 11, 2: 210} Explanation 2: key 0 → value 5 key 1 → value 5+6 = 11 key 2 → value 5x6x7 = 210.

- In C++, you are going to write a program that implements a doubly linked list. The data must be read from the files and you can put the file names in your program. Letters.txt contains 26 English Letters: Copy the following exactly as it is into own .txt file to test: ABCDEFGHIJKLMNOPQRSTUVWXYZ Sequence.txt contains a list of numbers. Copy the following exactly as is into another .txt file3,-3,19,-19,18,1,-2,3,-18,17,1,-3,-13,14 You need to 1. Create a doubly linked list by reading the 26 letters from Letters.txt. 2. 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’. Then the second letter to output is the third element backward from the current position which is ‘A’. You…A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes in word pairs that consist of a name and a phone number (both strings), separated by a comma. That list is followed by a name, and your program should output the phone number associated with that name. Assume the search name is always in the list. Ex: If the input is: Joe, 123-5432 Linda, 983-4123 Frank, 867-5309 Frank the output is: 867-5309 461710 3116374.qx3zqy7A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow.

Each book should have the following information: book name, author name, ISBN, and publication year. Allow the user to add a new book to the linked list. Allow the user to delete a book from the linked list based on ISBN. Allow the user to search for a book in the linked list based on book name, author name, ISBN or publication year. Display the list of all books in the library. Note: The program should use the linked list implementation for storing the books and should not use any built-in library functions for linked lists.Write a C++ program to create a queue. The size of the queue will be dependent on the user. Insert the numbers in the queue till the queue reaches the size. Create a menu and perform the following function on that queue.
