![]() ![]() What is Big O Notation, and why does it matter “Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. Best, Average, Worst, Expected Complexity.Complexity Comparison Between Typical Big Os.What is Big O notation, and why does it matter.In the end, we will discuss some of the limitations of Big O in a practical scenario. After that we will go over some common variations of Big O notation. Then, we will go into the mathematics a little bit to have a formal understanding. We will start with an example algorithm to open up our understanding. In this article, we will have an in-depth discussion about Big O notation. Also, some in-depth material also requires high-school math fundamentals, and therefore can be a bit less comfortable to total beginners. This article is written with the assumption that you have already tackled some code. It is a good practice for software engineers to understand in-depth as well. If you haven’t, we will go over it here, and then get a deeper understanding of what it really is.īig O notation is one of the most fundamental tools for computer scientists to analyze the cost of an algorithm. ![]() If you have taken some algorithm related courses, you’ve probably heard of the term Big O notation. If not, don’t worry - come and join us for some endeavors in computer science. Do you really understand Big O? If so, then this will refresh your understanding before an interview. ![]()
