Big O Notation
SaveBig O Notation is a mathematical notation used to describe the efficiency of an algorithm. In other words, it describes how the running time or space requirements of an algorithm grow as the input size grows. Understanding Big O Notation is essential for computer scientists, programmers, and anyone interested in understanding the performance of algorithms.
Why Learn Big O Notation?
There are several reasons why you should learn Big O Notation:
-
It helps you understand the performance of algorithms.
Big O Notation allows you to compare different algorithms and choose the most efficient one for a given problem. By understanding the time and space complexity of an algorithm, you can make informed decisions about which algorithm to use in a particular situation. -
It helps you optimize your code.
Once you understand the performance characteristics of your code, you can identify areas for improvement. You can then optimize your code to make it more efficient and to reduce its running time and space requirements. -
It is a valuable skill for job interviews.
Many employers ask questions about Big O Notation in job interviews for software engineering positions. Being able to answer these questions shows that you have a strong understanding of computer science fundamentals.
