What is insertion and deletion in stack?

Insertion and deletion in stacks takes place only from one end of the list called the top. Insertion and deletion in queues takes place from the opposite ends of the list. The insertion takes place at the rear of the list and the deletion takes place from the front of the list.

The principal benefit of a linked list over a conventional array is that the list elements can be easily inserted or removed without reallocation or reorganization of the entire structure because the data items need not be stored contiguously in memory or on disk, while restructuring an array at run-time is a much more …

From a memory allocation point of view, linked lists are more efficient than arrays. Unlike arrays, the size for a linked list is not pre-defined, allowing the linked list to increase or decrease in size as the program runs.

It’s an efficiency question. LinkedList is fast for adding and deleting elements, but slow to access a specific element. ArrayList is fast for accessing a specific element but can be slow to add to either end, and especially slow to delete in the middle.

Advantages of Linked List

• The linked list is a dynamic data structure.
• You can also decrease and increase the linked list at run-time.
• In this, you can easily do insertion and deletion functions.
• Memory is well utilized in the linked list.

Stack is a data structure to which a data can be added using the push () method and data can be removed from it using the pop () method. With Linked list, the push operation can be replaced by the addAtFront () method of linked list and pop operation can be replaced by a function which deletes the front node of the linked list.

The output of this program will be: You can add elements to either the beginning, middle or end of the linked list. 1. Insert at the beginning 2. Insert at the End 3. Insert at the Middle You can delete either from the beginning, end or from a particular position. 1. Delete from beginning 2. Delete from end 3. Delete from middle

Delete from a Linked List 1 Delete from beginning Point head to the second node head = head->next; 2 Delete from end Traverse to second last element Change its next pointer to null struct node* temp = head; while(temp->next->next!=NULL) { temp = temp->next; } temp->next = NULL; 3 Delete from middle

A stack data structure can be implemented by using a linked list data structure. The stack implemented using linked list can work for an unlimited number of values. That means, stack implemented using linked list works for the variable size of data.
