LIFO stands for Last-In-First-Out. It is a data structure concept and a method of organizing data in a queue. In a LIFO data structure, the last item to be added to the queue is the first one to be removed. This is in contrast to a FIFO (First-In-First-Out) data structure, in which the first item to be added to the queue is the first one to be removed.
LIFO is commonly used in computer science and programming, especially in the implementation of stacks, which are a type of data structure used to store and manage data. Stacks in computer science follow the LIFO principle, with the most recently added item being the first one to be removed, similar to how a stack of plates works
