Which data structure uses Last-In, First-Out ordering?

Last-In, First-Out ordering is a property of a stack. Think of a stack of plates: you add new plates on top and you take from the top. The most recently added item is the first one to be removed, which is why it’s LIFO. Stacks support push (add to the top) and pop (remove from the top), enforcing this order. This is different from a queue, which removes items in the order they were added (FIFO). A graph is a network of nodes and edges, not about the order of removal, and an array is just a fixed sequence of elements—no inherent rule that dictates removal order unless you implement stack-like operations on it.
