Part II: Implement text compression. In this part, use a text file as input, read through the text file, calculate the frequencies of each character, apply your Huffman Algorithm to encode the text file into a new file. You program should have the following functions, besides the above functions. Encode: takes a text file name, calls the Huffman coding algorithm, traverse the tree to get the code word, and then encode the text file into a new file. Decode: takes a prefix tree, and an encoded file, decode the file. What to turn in: Well documented source code in C++. Run your algorithm for 20 files and show the compression ratio of the size of the original file and the size of the compressed file. Show the ratios in the table. //code // C++ program for Huffman Coding #include <iostream> #include<queue> #include<vector> #include<string> #include<map> using namespace std; /*structure to represent node of huffman tree*/ struct node { // One of the…

C++ please Please complete Programming Exercise 4, from pages 1402, from chapter 19 from your textbook. Write a function, singleParent, that returns the number of nodes in abinary tree that have only one child. Add this function to the classbinaryTreeType and create a program to test this function. (Note: Firstcreate a binary search tree.)
Instructions. c++ binary search trees. 1. Implement a function that will build a binary search tree. 2. Using the function above create a binary search tree. 3. Implement a swapSubtrees() function that will take a pointer to a root node and a target value. Function will search for the target value in the tree and swap all left nodes with right nodes for all descendant nodes. 4. Pass the tree created in step 2 to test swapSubtrees() function. 5. You can use the inorder, postorder or preorder traversal implemented in class to display and confirm the logic. (trace it by hand as well) TreeNode{ int val; TreeNode* left = nullptr; TreeNode* right = nullptr; TreeNode(){} TreeNode(int val): val(val){} };

Q#4. Construct Binary Trees from given Mathematical Expressions i. T-P/Y^ (R + G)
Distance between two mile stones (20pts + 5pts) The city map has a binary tree to show distances based on the milestone markings. Starting with milestone 1 at the "city center", all other major destinations are shown as follows, Main street 2 Perth street City center King corner City grounds University ave Meridian Ave Museum Street Given two locations, write a function that returns the distance between these two locations where the distance between two nodes is the number of edges along the shortest path. Give the runtime of this algorithm.
write a c++ code using binary search tree to store ten names of cities, search city names in tree, remove three cities name, beside the used cities in code add two new names of cities and search those newly added cities (code consist of all of above tasks)

DeleteAll() deletes all the nodes in the binary tree recurively. findNode(int item) //finds the node in the tree ITERATIVELY. countNonLeaves() takes a binary tree and counts the number of nodes that are not leaves in the given Binary Tree. OneChild() Calculate the number of nodes that have only one child in a given Binary Tree. findRange() return the range value of a Binary Search Tree. [ max(BST), min(BST) ] where max is the maximum value of the BST and min is theminimum value of the given BST. All of these functions should be called in the main and tested. Thank you.
*Please using JAVA only* Objective Program 3: Binary Search Tree Program The primary objective of this program is to learn to implement binary search trees and to combine their functionalities with linked lists. Program Description In a multiplayer game, players' avatars are placed in a large game scene, and each avatar has its information in the game. Write a program to manage players' information in a multiplayer game using a Binary Search (BS) tree for a multiplayer game. A node in the BS tree represents each player. Each player should have an ID number, avatar name, and stamina level. The players will be arranged in the BS tree based on their ID numbers. If there is only one player in the game scene, it is represented by one node (root) in the tree. Once another player enters the game scene, a new node will be created and inserted in the BS tree based on the player ID number. Players during the gameplay will receive hits that reduce their stamina. If the players lose…
