Explanation of Solution
Queue:
A queue is a linear data structure used to store a set of data and is the collection of data that uses FIFO (first-in-first-out) order for performing operations.
- Queue is opened at both its ends. One end is for inserting items to the queue called “rear” end and the other end is for removing the items from the queue called “front” end.
- Two basic operations done on queue are,
- enqueue() – add an item to queue.
- dequeue() – remove an item from the queue.
- When the “enqueue()” method is invoked, it checks whether the queue is full or not.
- If the queue is full, it throws an exception.
- If the queue has slots available, then element is added at the “rear” end...

- Don't copy from anywhere... please fast... typed answer Assignment: Linked List of Students You have been tasked with implementing a program in Java that uses a linked list to store and manage a list of students in a class. Each student should have a name and a grade. Your program should include the following classes: Student: Represents a student in the class. Each student should have a name and a grade. Node: Represents a node in the linked list. Each node should store a reference to a student and a reference to the next node in the list. LinkedList: Represents the linked list itself. Each linked list should have a reference to the first node in the list. Your task is to implement these classes using a linked list and demonstrate their functionality by creating a console-based interface for users to interact with the system. Your program should allow users to: Add a new student to the class at the end of the list. View information about a student, including their name and grade.…arrow_forwardEXPLAIN Collection through Enumeratorsarrow_forwardWhat are the advantages of a linked list versus an array?arrow_forward

- You need to implement a class named "Queue" that simulates a basic queue data structure. The class should have the following methods: Enqueue(int value) - adds a new element to the end of the queue Dequeue() - removes the element from the front of the queue and returns it Peek() - returns the element from the front of the queue without removing it Count() - returns the number of elements in the queue The class should also have a property named "IsEmpty" that returns a boolean indicating whether the queue is empty or not. Constraints: The queue should be implemented using an array and the array should automatically resize when needed. All methods and properties should have a time complexity of O(1) You can write the program in C# and use the test cases to check if your implementation is correct. An example of how the class should be used: Queue myQueue = new Queue(); myQueue.Enqueue(1); myQueue.Enqueue(2); myQueue.Enqueue(3); Console.WriteLine(myQueue.Peek()); // 1…arrow_forward6. Suppose that we have defined a singly linked list class that contains a list of unique integers in ascending order. Create a method that merges the integers into a new list. Note the additional requirements listed below. Notes: ● . Neither this list nor other list should change. The input lists will contain id's in sorted order. However, they may contain duplicate values. For example, other list might contain id's . You should not create duplicate id's in the list. Important: this list may contain duplicate id's, and other list may also contain duplicate id's. You must ensure that the resulting list does not contain duplicates, even if the input lists do contain duplicates.arrow_forwardC++ Question You need to write a class called LinkedList that implements the following List operations: public void add(int index, Object item); // adds an item to the list at the given index, that index may be at start, end or after or before the // specific element 2.public void remove(int index); // removes the item from the list that has the given index 3.public void remove(Object item); // finds the item from list and removes that item from the list 4.public List duplicate(); // creates a duplicate of the list // postcondition: returns a copy of the linked list 5.public List duplicateReversed(); // creates a duplicate of the list with the nodes in reverse order // postcondition: returns a copy of the linked list with the nodes in 6.public List ReverseDisplay(); //print list in reverse order 7.public Delete_Smallest(); // Delete smallest element from linked list 8.public List Delete_duplicate(); // Delete duplicate elements from a given linked list.Retain the…arrow_forward
