- The level of a node in the tree is the number of nodes in the path from the root to the node (including itself). For example, the node 15 in the example tree above has a level of 2. Write a function prune-tree that will take a tree representation as well as an integer level. It will return a new tree containing only nodes that have level not exceeding level. The order of the nodes in the result list should be the same as the original order in the tree. You may assume that level is a non-negative integer. write the program in racketHelp in C++ please: Write a program (in main.cpp) that: Prompts the user for a filename containing node data. Outputs the minimal spanning tree for a given graph. You will need to implement the createSpanningGraph method in minimalSpanTreeType.h to create the graph and the weight matrix. There are a few tabs: main.cpp, graphType.h, linkedList.h, linkedQueue.h, queueADT.h, minimalSpanTreeType.h, and then two data files labeled: CH20_Ex21Data.txt, CH20Ex4Data.txtC++ DATA STRUCTURES Implement the TNode and Tree classes. The TNode class will include a data item name of type string,which will represent a person’s name. Yes, you got it right, we are going to implement a family tree!Please note that this is not a Binary Tree. Write the methods for inserting nodes into the tree,searching for a node in the tree, and performing pre-order and post-order traversals.The insert method should take two strings as input. The second string will be added as a child node tothe parent node represented by the first string. Hint: The TNode class will need to have two TNode pointers in addition to the name data member:TNode *sibling will point to the next sibling of this node, and TNode *child will represent the first child ofthis node. You see two linked lists here??? Yes! You’ll need to use the linked lists
- True/False Select true or false for the statements below. Explain your answers if you like to receive partial credit. 3) Which of the following is true about the insertBeforeCurrent function for a CircularLinked List (CLL) like you did in programming exercise 1?a. If the CLL is empty, you need to create the new node, set it to current, andhave its next pointer refer to itselfb. The worst case performance of the function is O(n)c. If you insert a new element with the same data value as the current node, theperformance improves to O(log n)I have an assignment that requires me to read strings from a text file and insert them into a binary search tree. I am having a hard time reading the data from the file and passing it through a function. This is the code I have right now: struct tree_node {char *data;tree_node *left;tree_node *right;}; char **Read();tree_node *create_node(char **val); int main(){tree_node *root= NULL, *temp_node;char **val = (char**)malloc(sizeof(char*)*17);for (int i = 0; i < 17; i++) {val[i] = (char*)malloc(sizeof(char)*strlen(*val));}temp_node = create_node(val);root = insert(root, temp_node);printf("In Order: ");inorder(root);printf("\n");return 0;} char **Read() {int size;FILE *fp = fopen("in.txt", "r");fscanf(fp, "%d", &size);char** value = (char**)malloc(sizeof(char*));for(int i = 0; i < size; i++) {fscanf(fp, "%s", &value[i]);} fclose(fp);return value;} tree_node *create_node(char **val) {tree_node* temp = (tree_node*)malloc(sizeof(tree_node));for(int i = 0; i < 17; i++)for(int…8-Write a procedure that takes a tree (represented as a list) and returns a list whose elements are all the leaves of the tree arranged in right to left order or left to right. For example, ( leaves '((1 2) ((3 4) 5 )) returns (1 2 3 4 5) or (5 4 3 2 1). Then, Manually trace your procedure with the provided example.
- Write a C++ class called BSTArray with five basic functions for the BST: insert, search, findmin, findmax, and print: 1. int search(x): Find and return the index that stores element x using binary search tree mechanism. Print out all the elements in the search path. You must use the binary tree search algorithm. In other words, do NOT just do a linear search of the array. If the x value is not found, report an error and return -1. 2. int findmax( ): Find and return maximum value in BST. You must use the binary tree search algorithm. In other words, do NOT just perform a linear search of the array. If the tree is empty, return -1. 3. int findmin( ): Find and return minimum value in BST. In other words, do NOT just perform a linear search of the array. If the tree is empty, return -1. 4. void print( ): Print out the BST structure in the form of an array with index. Specifically, print the index of the array and the value stored at that index starting at zero and ending at the capacity of…Computer Science In c++ (There should be three different files, "main.cpp", "sourcefile.cpp" and "header.cpp" your solution must have those three different files): Write a function that checks if the nodes in a linked list is sorted in ascending order. The function should return true if the values are sorted, otherwise false. Take user input. Call the funciton in the main function to show it is working.Data Structure and algorithms ( in Java ) Please solve it urgent basis: Make a programe in Java with complete comments detail and attach outputs image: Question is inside the image also: a). Write a function to insert elements in the sorted manner in the linked list. This means that the elements of the list will always be in ascending order, whenever you insert the data. For example, After calling insert method with the given data your list should be as follows: Insert 50 List:- 50 Insert 40 List:- 40 50 Insert 25 List:- 25 40 50 Insert 35 List:- 25 35 40 50 Insert 40 List:- 25 35 40 40 50 Insert 70 List:- 25 35 40 50 70 b).

- In this task you will work with the linked list of digits we have created in the lessons up to this point. As before you are provided with some code that you should not modify: A structure definition for the storage of each digit's information. A main() function to test your code. The functions createDigit(), append(), printNumber(), freeNumber(), readNumber() and divisibleByThree() (although you may not need to use all of these). Your task is to write a new function changeThrees() which takes as input a pointer that holds the address of the start of a linked list of digits. Your function should change all of those digits in this linked list that equal 3 to the digit 9, and count how many replacements were made. The function should return this number of replacements. Provided codeMake sure the program run smooth and perfectly, make sure no error encounter. compatible for python software.
