Detailed explanation-1: -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-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: -The data structure that implements LIFO is Stack.
Detailed explanation-4: -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. Conversely, FIFO refers to First In First Out.
Detailed explanation-5: -Calling this structure a stack is by analogy to a set of physical items stacked one atop another, such as a stack of plates. The order in which an element added to or removed from a stack is described as last in, first out, referred to by the acronym LIFO.
