Question
Transcribed Image Text:Here is the transcription of the code snippet found in the image:
---
Assume class `LinkedQueue` has been defined using the implementation in your textbook that `myQueue` has been initialized so it is empty. Type the EXACT output of the following code segment. You may assume that the code compiles and executes without errors.
```cpp
LinkedQueue<int> myQueue;
int i = 1;
int j = 2;
int k = 3;
int n = 4;
myQueue.enqueue(n);
myQueue.enqueue(j);
i = myQueue.peekFront();
myQueue.dequeue();
myQueue.enqueue(k);
n = myQueue.peekFront();
myQueue.dequeue();
myQueue.enqueue(j);
myQueue.enqueue(n);
while (!myQueue.isEmpty())
{
i = myQueue.peekFront();
myQueue.dequeue();
cout << i << " ";
}
cout << endl;
```
---
This code snippet demonstrates basic operations on a `LinkedQueue`, such as `enqueue`, `dequeue`, and `peekFront`. The sequence of operations modifies the queue's state by adding and removing elements and outputs each element as it is dequeued.
The code initializes four integers `i`, `j`, `k`, and `n` with values 1, 2, 3, and 4, respectively. It then performs a series of operations on `myQueue`. The queue's contents change throughout the code segment based on these operations.
The exact order of elements processed can be determined by simulating the queue’s behavior given the operations that manipulate it.

- JAVA CODE Learning Objectives: Detailed understanding of the linked list and its implementation. Practice with inorder sorting. Practice with use of Java exceptions. Practice use of generics. You have been provided with java code for SomeList<T> class. This code is for a general linked list implementation where the elements are not ordered. For this assignment you will modify the code provided to create a SortedList<T> class that will maintain elements in a linked list in ascending order and allow the removal of objects from both the front and back. You will be required to add methods for inserting an object in order (InsertInorder) and removing an object from the front or back. You will write a test program, ListTest, that inserts 25 random integers, between 0 and 100, into the linked list resulting in an in-order list. Your code to remove an object must include the exception NoSuchElementException. Demonstrate your code by displaying the ordered linked list and…arrow_forwardIn C++, can I get a code example for a function that will return the intersection items for two sets.

I am looking for an actual function preferably for a set class, comparing one instance of a set class with another, but definitely NOT a STL keyword. Thank you.arrow_forwardTrue/False 6.

- in c++ Write a function that takes a queue with 20 integer values and deletes the elements thatare between 15 and 20. 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.arrow_forwardCan you help me with a C++ programming task I am trying to complete for myself 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.txtarrow_forwardIn C++ I need to write a recursive function insertEnd that will call a recursive method insertEnd(const ItemType& newEntry, Node<ItemType>* node), to insert newEntry at the end of the linked list I completely stuck and can't figure out where the error is coming from. main #include <iostream> #include "LinkedList.cpp" int main() { Node<int>* first = new Node(1); Node<int>* second = new Node(2); Node<int>* third = new Node(3); first->next = second; second->next = third; cout<<first->data<<endl; cout<<first->next->data<<endl; cout<<first->next->next->data<<endl; LinkedList<int> list; //an empty linked list for(int i =0; i<10; i++){ list.inserEnd(i); list.display(); } return 0; } linkedlist.cpp #include "LinkedList.h" #include "iostream" using namespace std; template <class T> LinkedList<T>::LinkedList(){ head = nullptr; } template <class…arrow_forward
