Question:

Which of the following data structures operates on a Last In, First Out (LIFO) basis?

Options:

    
• A) Queue
    
• B) Stack
    
• C) Linked List
    
• D) Array

Correct Answer: B) Stack

Explanation:

A Stack is a linear data structure that follows the LIFO (Last In, First Out) principle, meaning the last element added is the first one to be removed. Standard operations on a stack include push (to add an element) and pop (to remove the most recently added element).

Why the other options are incorrect:

    
• Queue: Follows the FIFO (First In, First Out) principle, where elements are inserted at the rear and removed from the front.
    
• Linked List: A dynamic data structure where elements can be accessed, inserted, or removed at any position, not strictly following LIFO.
    
• Array: An indexed collection of elements that allows random access based on index positions.
