编程中的FIFO与LIFO方法

先决条件–编程中的FIFO(先进先出)方法
FIFO是先入先出的缩写。这是一种用于处理数据结构的方法，其中首先处理第一个元素，最后处理最新的元素。

现实生活中的例子：

LIFO是“后进先出”的缩写，与“拳头后进” (FILO)相同。它是一种处理数据结构的方法，其中最后一个元素首先被处理，而第一个元素最后被处理。

现实生活中的例子：

以下是FIFO与LIFO的比较：

FIFO	LIFO
It stands for First-In-First-Out approach in programming.	It stands for Last-In-First-Out approach in programming.
In this, the new element is inserted below the existing element, So that the oldest element can be at the top and taken out first.	In this, the new element is inserted above the existing element, So that the newest element can be at the top and taken out first.
Therefore, the First element to be entered in this approach, gets out First.	Therefore, the First element to be entered in this approach, gets out Last.
In computing, FIFO approach is used as an operating system algorithm, which gives every process CPU time in the order they arrive.	In computing, LIFO approach is used as a queuing theory that refers to the way items are stored in types of data structures.
The data structure that implements FIFO is Queue.	The data structure that implements LIFO is Stack.
