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: -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.
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 container of objects that are inserted and removed according to the last-in first-out (LIFO) principle. Queue is a container of objects (a linear collection) that are inserted and removed according to the first-in first-out (FIFO) principle.
