O NOTATION Meaning and
Definition
-
O notation, also known as Big O notation, is a mathematical tool used to describe the time complexity of an algorithm or the efficiency of a computational process. It is widely used in computer science and mathematics to analyze and compare the efficiency of different algorithms based on their input size.
In simple terms, O notation provides an upper bound for the growth rate of an algorithm's time or space requirements as the input size increases. It expresses the worst-case scenario of how an algorithm's performance scales. The O notation is represented using the letter "O" followed by a mathematical function that describes the algorithm's time complexity.
For example, if an algorithm is said to have O(n) time complexity, it means that the time required to run the algorithm increases linearly with the size of the input. Similarly, O(n^2) denotes a quadratic time complexity, indicating that the time required increases with the square of the input size.
O notation is useful for comparing algorithms and determining their scalability as the input grows. It allows developers and researchers to analyze the efficiency of different algorithms and make informed decisions about which solution may be more suitable for a given problem.
Overall, O notation serves as a standardized and concise way to describe the time complexity and efficiency of algorithms, helping to understand their performance characteristics and make informed decisions in the field of computer science and beyond.

Etymology of O NOTATION
The term "O notation" is derived from the mathematical symbol "Big O", which represents a particular type of notation used to describe the growth rate or complexity of algorithms. It was introduced by the Danish mathematician Paul Bachmann in the late 19th century, and later popularized and formalized by the Russian mathematician Ivan Vinogradov in 1927.
The "O" in Big O stands for "order", signifying the order of magnitude of a function. It is used to analyze the efficiency of algorithms and describe how the algorithm's performance grows relative to the input size. The notation is often used in computer science and algorithm analysis to provide a standardized way of expressing the worst-case scenario of an algorithm's time or space complexity.
