in c++ Write a function that takes a queue with 20 integer values and deletes the elements that are between 15 and 20. In other words, only the elements less than 15 or greater than 20 remain in the queue. This means that you need to have an auxiliary queue to store the elements between 15 and 20 and restore them back to the original queue.

Use C++ Programming language: Design and implement your own linked list class to hold a sorted list of integers in ascending order. The class should have member functions for inserting an item in the list (in ascending order), deleting an item from the list, and searching the list for an item. Note: the search function should return the position of the item in the list (first item at position 0) and -1 if not found. In addition, it should have member functions to display the list, check if the list is empty, and return the length of the list. Be sure to have a class constructor a class destructor, and a class copy constructor for deep copy. Demonstrate your class with a driver program (be sure to include the following cases: insertion at the beginning, end (note that the list should alway insert in ascending order. However, in your test include a case where the inserted item goes at the beginning of the list), and inside the list, deletion of first item, last item, and an item...

Write a function, to be included in an unsorted linked list class, called replace_item, that will receive two parameters, one called olditem, the other called newitem. The function will replace all occurrences of olditem with newitem ( if olditem exists !! ) and it will return the number of replacements done.

Use C++

Write a function that accepts two lists as it's only arguments. The function should return a new list containing all the elements of the two list arguments. For example, if the function was passed the lists [1, 2, 3] and [4, 5, 6], it would return a new list containing [1, 2, 3, 4, 5, 6]

5. The following function indexCounter aims to find and return all the indices of the element x in a list L. if x is not in the list L, return an empty list. However, the implementation has a flaw, so that many times it will return error message. Can you fix the flaw? def indexCounter(L, x): indexList [] startIndex = 0 while startIndex < len(L): indexList.append (L.index (x, startIndex)) startIndex = L.index (x, startIndex) + 1 return indexList

for c++ please thank you please type the code so i can copy and paste easily thanks. 4, List search Modify the linked listv class you created in the previous programming challange to include a member function named search that returns the position of a specific value, x, in the lined list. the first node in the list is at position 0, the second node is at position 1, and so on. if x is not found on the list, the search should return -1 test the new member function using an approprate driver program. here is my previous programming challange. #include <iostream> using namespace std; struct node { int data; node *next; }; class list { private: node *head,*tail; public: list() { head = NULL; tail = NULL; } ~list() { } void append() { int value; cout<<"Enter the value to append: "; cin>>value; node *temp=new node; node *s; temp->data = value; temp->next = NULL; s = head; if(head==NULL) head=temp; else { while (s->next != NULL) s = s->next; s->next =...

in haskell: Write a function sumNums that adds the items in a list and returns a list of the running totals. For example: sumNums [2,3,4,5] returns [2,5,9,14].

In c++ please

Every time you write a non-const member function for a linked list, you should always think about if that function is preserving your class invariants. Group of answer choices A. True B. False
