The phrase order of is denoted by O, which is where we obtain the term Big-O. When we read Big-O notation, we say that an algorithm is of order x, where x is the function used to assess a certain algorithm's running time.įor example, when measuring a searching algorithm, we might say that this search algorithm is of order n. With this in mind, let us consider how exactly Big-O is used and the different functions used to assess the running time. Thus, why learn Big-O notation? Big-O notation is useful, if one wishes to abstract away and assess the running time by utilizing the code, which is being considered, rather than by always having to write benchmarks every single time the algorithm is being assessed.īig-O notation gives us a more practical, general manner by which one can evaluate the performance of an algorithm at the code level, using any programming language, any computer and any operating system. An Intel processor may take fourteen milliseconds to add two integers, while an AMD processor may take fifteen to accomplish the same goal. If one wishes to know the exact running time of an algorithm running on a particular processor, he or she must write benchmarks to obtain such information. Note that this is a theoretical tool to measure the running time. These functions were chosen based on how long a particular operation takes to accomplish its goal(s).
There are a few popular mathematical functions, which are used to measure the running time of a C# method, for example. Simply stated, Big-O notation is a mathematical tool, which computer scientists and software developers use to assess the running time of an algorithm. From: Introduction to Data Structures & Algorithms in Java. We are given an array and a set of query ranges, we are required to find the sum of every query range. Let us consider the following problem to understand MO’s Algorithm.
