MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A stack follows the LIFO (Last In First Out) principle, i.e., the element inserted at the last is the first element to come out. The insertion of an element into the stack is called push operation, and the deletion of an element from the stack is called pop operation.

Detailed explanation-2: -The primary difference between Stack and Queue Data Structures is that Stack follows LIFO while Queue follows FIFO data structure type. LIFO refers to Last In First Out. It means that when we put data in a Stack, it processes the last entry first.

Detailed explanation-3: -Last-In-First-Out In a LIFO data structure, the newest element added to the container will be processed first. Sometimes this will be called a stack and is usually pictured as below. The new element is always added at the end of the stack.

Detailed explanation-4: -Stack is a linear data structure that follows a particular order in which the operations are performed. The order may be LIFO(Last In First Out) or FILO(First In Last Out).

Detailed explanation-5: -Since the element at the top of the stack is the most recently inserted element using the insert operation, and it is also the one to be removed first by the delete operation, the stack is called a Last In First Out (LIFO) list.
