How to use Tabs in ASP.NET CORE

I want to show Components in a tabs , so first of all create few components. In this project we have three components, First View Component  public class AllViewComponent : ViewComponent     {         private readonly UserManager<ApplicationUser> _userManager;         public AllViewComponent(UserManager<ApplicationUser> userManager)         {             _userManager = userManager;         }         public async Task<IViewComponentResult> InvokeAsync()         {             List<StudentViewModel> allUsers = new List<StudentViewModel>();             var items = await _userManager.Users.ToListAsync();             foreach (var item in items)             {                 allUsers.Add(new StudentViewModel {Id=item.Id, EnrollmentNo = item.EnrollmentNo, FatherName = item.FatherName, Name = item.Name, Age = item.Age, Birthdate = item.Birthdate, Address = item.Address, Gender = item.Gender, Email = item.Email });             }            

Implementation of Circular Queue using 1-d array

Implementation of Circular Queue using 1-d array: 

  The Circular QUEUE can be represented graphically as consecutive blocks when it is implemented using one-dimensional circular array. N the maximum number of elements can be added into the QUEUE is called as size of QUEUE. To represent a QUEUE an array of size N can be used:

 In the above representation the size of QUEUE is 8. FORNT and REAR index variables can be used to do the DELETE and ADD operations respectively. Initially when the QUEUE is empty FORNT and REAR are assigned with a value 0, because of Lower Bound 1 of the array. When both are equal to 0, then the 
QUEUE is said to be empty.
              When first element is added into QUEUE, REAR and FRONT are both incremented by 1 and the element to be added is placed at REAR index of QUEUE, QUEUE is the name of the array i.e. FORNT<--1, REAR<--1 and QUEUE [REAR]<--ITEM. ITEM is the element to be added to QUEUE. In the further addition operations, the REAR is incremented by 1 and the ITEM is copied at REAR index. When the REAR=N, then REAR is set equal to 1 and addition is done at REAR index. When the REAR is equal to N and FRONT=1 OR FORNT=REAR+1, QUEUE is    said to be full. If any addition is done when the QUEUE is full, ‘overflow’ occurs.
             When the element is to be deleted from the QUEUE, the element stored in the QUEUE with FRONT index is deleted by copying it in ITEM and the incrementing FRONT by 1. When FRONT=N then FORNT is set equal to 1. When FRONT is equal to 0, the QUEUE is empty. When the QUEUE is empty and if the deletion operation is done ‘underflow’, occurs.
Example: Consider a QUEUE of size 8. It is initially represented as follows:



        In order to implement the Circular QUEUE using one-dimensional array, an array of size N is used with name QUEUE and FRONT and REAR as the indices to represent the deletion end and addition end respectively. Following algorithms are used for the purpose.

Polynomial representation using Linked List for Data Structure in 'C'

Polynomial representation using Linked List The linked list can be used to represent a polynomial of any degree. Simply the information field is changed according to the number of variables used in the polynomial. If a single variable is used in the polynomial the information field of the node contains two parts: one for coefficient of variable and the other for degree of variable. Let us consider an example to represent a polynomial using linked list as follows: Polynomial:      3x 3 -4x 2 +2x-9 Linked List: In the above linked list, the external pointer ‘ROOT’ point to the first node of the linked list. The first node of the linked list contains the information about the variable with the highest degree. The first node points to the next node with next lowest degree of the variable. Representation of a polynomial using the linked list is beneficial when the operations on the polynomial like addition and subtractions are performed. The resulting polynomial can also

Memory representation of Linked List Data Structures in C Language

                                 Memory representation of Linked List              In memory the linked list is stored in scattered cells (locations).The memory for each node is allocated dynamically means as and when required. So the Linked List can increase as per the user wish and the size is not fixed, it can vary.                Suppose first node of linked list is allocated with an address 1008. Its graphical representation looks like the figure shown below:       Suppose next node is allocated at an address 506, so the list becomes,   Suppose next node is allocated with an address with an address 10,s the list become, The other way to represent the linked list is as shown below:  In the above representation the data stored in the linked list is “INDIA”, the information part of each node contains one character. The external pointer root points to first node’s address 1005. The link part of the node containing information I contains 1007, the address of
