What is a stack data structure?

A stack data structure allows elements to be added and removed from both ends.

A stack data structure supports operations such as insert and delete at any position.

A stack data structure is a Last In First Out (LIFO) data structure where elements are added and removed from the same end, called the top. It supports two main operations: push (adds an element to the top of the stack) and pop (removes the top element from the stack).

A stack data structure is a First In First Out (FIFO) data structure.

How is a stack different from a queue?

Stacks are typically implemented using a linked list, while queues are implemented using arrays.

In a stack, elements are added and removed from the same end following the Last In First Out (LIFO) principle. In a queue, elements are added at the rear and removed from the front following the First In First Out (FIFO) principle.

In a stack, elements are removed from the front, while in a queue, elements are removed from the rear.

Stacks allow random access to elements, while queues only allow sequential access.
