- 3) Implement the if __name__ == "__main__" : block at the bottom of this file to do the following: 3a) The if main block at the bottom should get the name of the highway graph file from the command line arguments. See the video in Python that explains how to get command line arguments. 3b) Call your parse_highway_graph_file function to parse that file, and to construct a WeightedGraph object from it. 3c) Write some code that outputs (with print statements) the degree of each vertex. You can have one vertex per line, indicating its id (just its 0-based index) followed by its degree. IMPORTANT: Your parse_highway_graph_file function should NOT produce any output. You will have code in your if main block that will have the print statements. The WeightedGraph class has a degree method, inherited from Graph that will return to you the degree of a vertex.14.12 NVCC Lab: Count number of subsets of a graph A graph is made up of a set of nodes called vertices and a set of lines called edges that connect the nodes. Informally, a connected component of a graph is a subset in which each pair of nodes is connected with each other via a path. For example, the following graph consists of two connected components (subsets). For this assignment, you are required to find out the number of connected components in a graph as specified below: implement the following method: public static int countConnectedComponents(String fileName): where fileName is the input data file representing a graph: each line in the data file contains two numbers representing a pair of vertices that are connected (an edge between these two nodes exists). For example, given the following data file: 1 2 1 3 2 3 4 5 6 8 6 7 *Code must be written in JAVAQ.2. Implement a single linked list. Elements of this linked list should be of integer type, user would provide values as input for elements of this linked list. Which does not allow insertion of duplicate value to the list.
- Object is name(age,time) For example : apple (1,11) the Binary tree order depend on age Write a java code that would add a new node to the tree in the leaf position where binary search determines a node for d should be inserted. To build fix the trees so that the properties of the max heap are maintained (i.e. the parent node must have higher adoption priority than its children). This means that we need to perform upheap if needed. Note that since this is also a binary search tree, we need to make sure that when performing upheap we don’t break the properties of the binary search tree. To ensure this, instead of performing upheap as seen in class, we will need to implement a tree rotation that reverses the parent-child relationship whenever necessary. Depending if the child that has to be swap in the parent position is the left or the right child, we will need to perform a right rotation or a left rotation8) Implement bucket sort with an array of lists data structure to sort i) a list of strings, ii) a list of floating point numbers and iii) a list of integers, which are uniformly distributed over a range, for an appropriate choice of the number of bucketsQuestion 1:Convert a decimal to binary and binary to decimal using recursionTest your implementation with following examples:● (1947)10 = (11110011011)2● (1992)10 = (11111001000)2● (2021)10 = (11111100101)2Question 2:Implement a member function that prints a singly linked list in reverse order without creating acopy or changing the original List.void printBackwards() constQuestion 3:Implement a recursive member function “isSorted” which recursively checks whether the linked listis sorted (ascendingly).bool isSorted() constQuestion 4:You will implement a function bool Equalize_Occurrences (char key, int maxcount) of theclass list, that will take a character key and maximum count for the consecutive occurrences of thekey inparameters. It will then traverse the list, verify and update the consecutive occurrences of the keyaccordingto maximum count and returns true. It returns false if no occurrence of key is found.Note: You can traverse the list only once for this task.
- 3. Consider a hospital information system using which patients can take appointment with a doctor on first come first serve basis and their appointments are maintained in a queue. a. Discuss by giving reasons on which of the following data structures is most suitable for implementing such appointment queue, when considering that there is no limit on how many patients a doctor can see in any given day. *One dimensional array Linked list b. Write and execute a java program to create an object of class appointment queue, and perform operations such as insert, remove, and display. Give your reflection on each of these operationIn C++, Implement a Priority Queue(PQ) using an UNSORTED LIST. Use an array size of 20 elements. Use a circular array: Next index after last index is 0. Add the new node to next available index in the array. When you add an element, add 1 to index (hit max index, go to index 0). Test if array in full before you add. When you remove an element, from the list, move the following elements to the left to fill in the blank, etc ( Like prior program done with LISTS ) Create a class called Node: Have a Name and Priority. Data set - 1 is the highest priority, 10 is lowest priority. Enqueue and dequeue in the following order. Function Name, Priority Enqueue Joe, 3 Enqueue Fred, 1 Enqueue Tuyet, 9 Enqueue Jose, 6 Dequeue Enqueue Jing, 2 Enqueue Xi, 5 Enqueue Moe, 3 Dequeue Enqueue Miko, 7 Enqueue Vlady, 8 Enqueue Frank, 9 Enqueue Anny, 3 Dequeue Enqueue Xi, 2 Enqueue Wali, 2 Enqueue Laschec, 6 Enqueue Xerrax, 8 Dequeue Dequeue Dequeue Dequeue Dequeue Dequeue Dequeue Dequeue Dequeue Dequeue…6.Need ri Write a JAVA program that will maintain a phone directory using a Linked-List. The program should be able to perform the following operations: Add persons details (first name, last name, phone number, city, address, sex and email) to the phone directory, where phone numbers in the directory have to be unique. (Note: each person record will store in one node in the linked-list and insert each person to the last) Delete any person details by a given phone number. Update telephone number by providing person first name. Display all details of persons from a phone directory. Search telephone number based on person first name. (Note: use sequential search to find all telephones for the given first name) Sort all persons in the phone directory ascending based on person first name. (Note: use bubble or selection sort to arrange the entire phone directory.
- S and Q are integer stacks and priority queues, respectively. C mod 3 is the priority of an element C joining the priority queue Q. In other words, the elements' priority numbers are either 0 or 1 or 2. What is the output of the following code if A, B, and C are integer variables?

Only head of the list will be given as parameter where you may assume every node can contain only integer as its element.Note: you’ll need a Singly Node class for this code. c) Implement a recursive algorithm which will print all the elements of a non-dummy headed singly linked linear list in reversed order. Example: if the linked list contains 10, 20, 30 and 40, the method will print 40 30 20 10 Note: you’ll need a Singly Node class for this code. complete the code by using python 3. Please do not use any Built-In function. Do not copy-paste from other sources.In a workspace array, a double linked list may be implemented by utilising just one index next. To locate the backward linkages, we do not need to maintain a distinct field back in the nodes that make up the workspace array. The goal is to insert a member workspace[current] rather than the index of the next item on the list into workspace[current]. difference equals the index of the entry after the current entry less the index of the item before it. We must additionally keep two pointers to subsequent nodes in the list, the current index and the prior index of the node right before current in the linked list.To find the next entry of the list, we calculate workspace[current].difference + previous; Similarly, to find the entry preceding previous, we calculate current − workspace[previous].difference;
