FIFO vs LIFO approach in Programming Last Updated : 27 Jul, 2022 Comments Improve Suggest changes Like Article Like Report FIFO is an abbreviation for first in, first out. It is a method for handling data structures where the first element is processed first and the newest element is processed last. Prerequisite - FIFO (First-In-First-Out) approach in Programming Real-life example: LIFO is an abbreviation for Last in, first out is the same as first in, last out (FILO). It is a method for handling data structures where the last element is processed first and the first element is processed last. A real-life example is shown below as follows: Below is a comparison of FIFO vs. LIFO: FIFOLIFOIt 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.Time complexity of inserting element in FIFO is O(1).Time complexity of inserting element in LIFO is O(1).The data structure that implements FIFO is Queue.The data structure that implements LIFO is Stack.

This type of programming is mainly used when solutions are easily expressed in function and hav 3 min read LIFO Principle in Stack LIFO stands for "Last In, First Out". This principle dictates that the last element added to the stack is the first one to be removed. In other words, the most recently added element is always at the top, and any operations on the stack will affect this top element. Use of LIFO principle in Stack:Pu 3 min read Print "GeeksforGeeks" in 10 different programming languages The most elementary part of learning any computer programming language is the ability to print a desired text on the screen or console.
