Understand the Problem
The question is asking about the main objective of Big O notation in the context of algorithms, specifically which of the provided options best describes its primary purpose.
Answer
To provide an upper bound on the running time of an algorithm.
The primary purpose of Big O notation is to provide an upper bound on the running time of an algorithm.
Answer for screen readers
The primary purpose of Big O notation is to provide an upper bound on the running time of an algorithm.
More Information
Big O notation is a mathematical representation used in computer science to assess the performance of an algorithm as the input size approaches infinity. Its primary role is to depict how the running time or space requirements increase with larger input sizes, which helps in understanding the efficiency of algorithms.
Tips
A common mistake is confusing Big O notation with measuring actual execution time or memory usage. It's important to note that Big O provides a growth perspective rather than concrete measures.
