To understand what Big O notation is, we can take a look at a typical example, O(n²), which is usually pronounced “Big O squared”. In plain words, Big O notation describes the complexity of your code using algebraic terms. Wikipedia’s definition of Big O notation It is a member of a family of notations invented by Paul Bachmann, Edmund Landau, and others, collectively called Bachmann–Landau notation or asymptotic notation.” 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.
