AI overview
A stack is a way of organizing data where items are added and removed from the same end, following a "last in, first out" principle—like a stack of plates where you take the top plate off first. This simple organizational method matters because it's useful for many computing tasks, such as undoing actions in software or managing how a computer processes nested instructions.

堆疊（stack）又稱為棧或堆叠，是计算机科學中的一種抽象資料型別，只允許在有序的線性資料集合的一端（稱為堆疊頂端，top）進行加入数据（push）和移除数据（pop）的運算。因而按照後進先出（LIFO, Last In First Out）的原理運作，堆疊常用一維数组或連結串列來實現。常與另一種有序的線性資料集合佇列相提並論。
