What is Last In, First Out (LIFO)?

Last In, First Out (LIFO) means the last thing you put in is the first thing you take out.

Imagine you have a stack of plates in the kitchen. You add one plate on top of another, that’s like putting things into a pile. When it's time to use a plate, you grab the top one, the last one you added. That’s LIFO in action!

Like a Toy Box

Think about a toy box. If you put your toys in one by one, first a car, then a doll, then a ball, and you want to take something out, you’ll probably grab the ball first because it's on top. The last toy you added is the first one you use. That’s LIFO!

A Real-Life Example

Imagine you’re eating sandwiches at lunchtime. You eat one sandwich, then another, and another, stacking them up like a tower. When you're done, you start with the top sandwich, the last one you ate. That's how LIFO works in real life.

LIFO is just like that toy box or your stack of plates, simple, fun, and easy to understand!
