- C++ Consider the following function as a property of a LinkedBag that contains a Doubly Linked List. Assume a Node has pointers prev and next, which can be read and changed with the standard get and set methods. Assume that the doubly linked list is: 1 <--> 2 <--> 3 <--> 4 <--> 5 <-->6 If you are uncertain what the above diagram depicts, it is a doubly linked list such that: The head of this doubly linked list is the node that contains the value 1. The tail of this doubly linked list is the node that contains the value 6. The 3rd node in this list contains the value 3. The contents of this list are the values 1 through 6 in sequential order. The following questions are regarding the linked list after after the test_function is run. A. The head of the list after the test_function is run contains the value: B. The tail of the list after the test_function is run contains the value: C. The 3rd node in the list after the test_function is run…Data Structure Using C++ (Queue) C++ code (NOT JAVA C++ JUST) C++ PROGRAMMING LANGUAGE PLEASE :: We can use a queue to simulate the flow of customers through a check-out line in a store. In this simulation we will have the following details: one check-out line the expected service time for each customer is one minute (However, they may have to wait in line before being serviced) between zero and two customers join the line every minute We can simulate the flow of customers through the line during a time period n minutes long using the following algorithm: Initialize the queue to empty. for ( minute = 0 ; minute < n ; ++minute ) { if the queue is not empty, then remove the customer at the front of the queue. Compute a random number k between 0 and 3. If k is 1, then add one customer to the line. If k is 2, then add two customers to the line. Otherwise (if k is 0 or 3), do not add any customers to the line. } In addition, the algorithm will keep track…C++ Binary Search Tree program Create a class "Person" with three member variables string first name, string last name, int age. The primary key will be the last name. User will be prompted with a menu with two options: 1, "Enter person", where they will enter the persons first name, last name and age, or 2, "View person list" where the person may view the information previously added.

In other words, only the elements less than 15 or greater than 20remain in the queue. This means that you need to have an auxiliary queue to store theelements between 15 and 20 and restore them back to the original queue.
- Topic: Doubly Linked List Deque Implement the following problem in the main case 0 (see attached photo) Your algorithm for the hierarchy problem should follow this: Evaluate the final set of operations first given the set of rules. Then, do the remove operations. Finally, do the add operations. DO NOT MIND THE #include "dlldeque.h" it is already implemented only the case 0 needs to be solved #include <iostream> #include <cstring> #include "dlldeque.h" using namespace std; int main(int argc, char** argv) { DLLDeque* deque = new DLLDeque(); int test; cin >> test; switch (test) { case 0: // perform your Hierarchy implementation here // utilize the deque initialized, // initialize variables you need before switch // you can use the print() method to debug, but not the final_print() // do not modify from this point onwards deque->final_print();…struct remove_from_front_of_dll { // Function takes no parameters, removes the book at the front of a doubly // linked list, and returns nothing. void operator()(const Book& unused) { //// TO-DO (13) |||| // Write the lines of code to remove the book at the front of "my_dll", // // Remember, attempting to remove an element from an empty data structure is // a logic error.

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.
- C++ Code for a QueueThe program should features a Queue class with insert(), remove(), peek(),isFull(), isEmpty(), and size() member functions.The main() program creates a queue of five cells, inserts four items, removes threeitems, and inserts four more. The sixth insertion invokes the wraparound feature. All the items are then removed and displayed. The output looks like this:40 50 60 70 80Language/Type: C++ binary trees pointers recursion Write a function named hasPath that interacts with a tree of BinaryTreeNode structures representing an unordered binary tree. The function accepts three parameters: a pointer to the root of the tree, and two integers start and end, and returns true if a path can be found in the tree from start down to end. In other words, both start and end must be element data values that are found in the tree, and end must be below start, in one of start's subtrees; otherwise the function returns false. If start and end are the same, you are simply checking whether a single node exists in the tree with that data value. If the tree is empty, your function should return false. For example, suppose a BinaryTreeNode pointer named tree points to the root of a tree storing the following elements. The table below shows the results of several various calls to your function: 67 88 52 1 21 16 99 45 Call Result Reason hasPath(tree, 67, 99) true path exists…Multiple choice in data structures Assume the function: void F(stack<T> &S){ } and we send a stack S to the function F, as a result of it Select one: a.
