Stack Stack is an Abstract Data Type (ADT) in which items are only inserted on or removed from the top of a stack. The stack push operation inserts an item on the top of the stack. The stack pop operation removes and returns the item at the top of the stack.  A stack is referred to as a Last-In First-Out (LIFO) ADT. A stack can be implemented using a linked list, an array, or a vector.    Suppos..

Array–Based List An array-based list is a list ADT implemented using an array. An array-based list supports the common list ADT operations, such as append, prepend, insert after, remove, and search.In many programming languages, arrays have a fixed size. An array-based list implementation will dynamically allocate the array as needed as the number of elements changes. Initially, the array-based ..

Doubly-Linked List A doubly-linked list is a data structure for implementing a list ADT, where each node has data, a pointer to the next node, and a pointer to the previous node. The list structure typically points to the first node and the last node. The doubly-linked list's first node is called the head, and the last node the tail. (same as singly–linked lists)Same as the singly–linked list, d..

Singly-Linked List Singly-Linked List is a data structure for implementing a list ADT, where each node has data and a pointer to the next node. The list structure typically has pointers to the list's first node and last node, called the head and tail, respectively.A singly-linked list is a type of positional list: A list where elements contain pointers to the next and/or previous elements in the..
