- Topic: Singly Linked ListImplement the following functions in C++ program. Read the question carefully. (See attached photo for reference) void isEmpty() This method will return true if the linked list is empty, otherwise return false. void clear() This method will empty your linked list. Effectively, this should and already has been called in your destructor (i.e., the ~LinkedList() method) so that it will deallocate the nodes created first before deallocating the linked list itself.HELP Write C code that implements a soccer team as a linked list. 1. Each node in the linkedlist should be a member of the team and should contain the following information: What position they play whether they are the captain or not Their pay 2. Write a function that adds a new members to this linkedlist at the end of the list.In C++ Plz LAB: Grocery shopping list (linked list: inserting at the end of a list) Given main(), define an InsertAtEnd() member function in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts ItemNode.h Default Code: #include <iostream>#include <string>using namespace std; class ItemNode {private: string item; ItemNode* nextNodeRef; public: // Constructor ItemNode() { item = ""; nextNodeRef = NULL; } // Constructor ItemNode(string itemInit) { this->item = itemInit; this->nextNodeRef = NULL; } // ConstructorItemNode(string itemInit, ItemNode *nextLoc) {this->item = itemInit;this->nextNodeRef = nextLoc;} // Insert node after this…
- Topic: Singly Linked ListImplement the following functions in C++ program. Read the question carefully. (See attached photo for reference) int removeAt(int pos) Removes the number in the posth position of the list and returns the element removed. Performing removeAt(3) in the example list will remove the 3rd element of the linked list and the updated list will be: 10 -> 30 -> 50 When the value of pos is greater than the size or less than one, return -1. int removeAll(int num) Removes all instances of num in the linked list and returns the number of instances removed. In this list 10 -> 10 -> 20 -> 30 -> 10, performing removeAll(10) will remove all three 10's and the list will look like this: 20 -> 30. Then, it will return the number of instances removed, in this case, 3. int contains(int num) This will return the position of the first instance of the element num in the list. If num is not found, return 0. In the example, having the method contains(30) will…linked_list_stack_shopping_list_manager.py This is a file that includes the class of linked list based shopping list manager. This class contains such methods as init, insert_item, is_list_empty, print_item_recursive_from_top, print_items_from_top, print_item_recursive_from_bottom, print_items_from_bottom, getLastItem, removeLastItem. In addition, this class requires the inner class to hold onto data as a linked list based on Stack. DO NOT use standard python library, such as deque from the collections module. Please keep in mind the following notes for each method during implementation: Init(): initializes linked list based on Stack object to be used throughout object life. insert_item(item): inserts item at the front of the linked list based on Stack. Parameters: item name. is_list_empty (): checks if the current Stack object is empty (ex. check if head is None). print_item_recursive_from_top(currentNode): a helper method to print linked list based on Stack item recursively. Note:…Programming in C: Challenge 1: Create and Print a Doubly Linked List In class, I briefly mentioned how to create a doubly linked list (a linked list with two directions: forward and backwards). This task challenges you to create a doubly linked list of 5 nodes. If your nodes were called n1, n2, n3, n4 and n5 (which they shouldn’t, please give them original names), your list should be linked as follows: We discussed what "start" and "end" should be. Then, also in main, you will have to print the list forwards by taking advantage of the arrows pointing to the right. You will also have to print it backwards taking advantage of the arrows pointing to the left. Again, everything must be done in main. Hint: look at the way in which I printed the singly linked list in class. In other words, if your nodes had the values: n1=1, n2=2, n3=3, n4=4 and n5=5; your program should print:1 3 5 2 4 (forwards) and 4 2 5 3 1 (backwards). Please give different values to your nodes, they should not have…
- Max Absolute In List Function Lab Description Implement function max_abs_val(lst), which returns the maximum absolutevalue of the elements in list.For example, given a list lst: [-19, -3, 20, -1, 0, -25], the functionshould return 25. The name of the method should be max_abs_val and the method should take one parameter which is the list of values to test. Here is an example call to the function print(max_abs_val([-19, -3, 20, -1, 0, -25])) File Name maxabsinlst.py Score There are three tests each worth 2 points Note: You do not need any other code including the main method or any print statements. ONLY the max_abs_val method is required. Otherwise, the autograder will fail and be unable to grade your code. (I.e., do not include the above example in your code.) The above example should be used be test your code but deleted or comment out upon submission. PYTHON LABC++ The List class represents a linked list of dynamically allocated elements. The list has only one member variable head which is a pointer that leads to the first element. See the following code for the destructor to List. ~ List () { for (int i = 0; i <size (); i ++) { pop_back (); } } What problems does the destructor have? Select one or more options: 1. There are no parameters for the destructor. 2. The return value from pop_back (if any) is nerver handled. 3. The destructor will create a stack overflow. 4. The destructor will create dangling pointers. 5.The destructor will create memory leaks. 6.The destructor will create undefined behavior (equivalent to zero pointer exception). 7.The condition must be: i <size () - 1 8. There is at least one problem with the destructor, but none of the above.(Circular linked lists) This chapter defined and identified various operations on a circular linked list.a. Write the definitions of the class circularLinkedList and its member functions. (You may assume that the elements of the circular linked list are in ascending order.)b. Write a program to test various operations of the class defined in (a).
- C++The List class represents a linked list of dynamically allocated elements. The list has only one member variable head which is a pointer that leads to the first element. See the following code for the copy constructor to List. List (const List & list) { for (int i = 0; i <list.size (); i ++) { push_back (list [i]); } } What problems does the copy constructor have? Select one or more options: 1. List (const List & list) {} does not define a copy constructor. 2. The list parameter should not be constant. 3. The new elements will be added to the wrong list. 4. Copy becomes shallow rather than deep. 5. The copy will create dangling pointers. 6. Copying will create memory leaks. 7. The condition must be: i <size () 8. head is never initialized.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.def normal (L): '' '(list of int) -> list Precondition: len (L)> = 1 This function must return a new list R which has the same contents of L except where there is a sequence of consecutive zeros, the list R must have only one zero such that in the examples: >>> normal ([1,2,0,0,0,3,0]) [1, 2, 0, 3, 0] >>> normal ([1,2,0,0,0,3,0,0,0,0]) [1, 2, 0, 3, 0] >>> normal ([0,0,1,0,2,0,0,0,3,0,0,0,0,0]) [0, 1, 0, 2, 0, 3, 0] >>> normal ([1,2,2,0,3,3,3,0]) [1, 2, 2, 0, 3, 3, 3, 0] '' ' [1, 2, 0, 3, 0] >>> tanganyika([1,2,0,0,0,3,0,0,0,0]) [1, 2, 0, 3, 0] >>> tanganyika([0,0,1,0,2,0,0,0,3,0,0,0,0]) [0, 1, 0, 2, 0, 3, 0] >>> tanganyika([1,2,2,0,3,3,3,0]) [1, 2, 2, 0, 3, 3, 3, 0] ''' Please: Do not use dictionaries.- Do not use sets- Do not use 'break'.- You cannot import a library or other module
